Customer Questions and Answers

Q1: What is the difference between CDA 360 Brass and other Brass alloys, and how does this affect component performance?

A1: CDA 360 Brass (C36000) differs from other Brass alloys primarily in its balanced composition of approximately 61.5% Copper, 35.5% Zinc, and 3% Lead. This specific formulation provides several advantages compared to alternative Brass alloys:

Compared to higher-copper Brasses like C27000 (Yellow Brass with 65% Copper), CDA 360 offers superior machinability while sacrificing some corrosion resistance and ductility. Compared to higher-zinc Brasses like C35300 (Low-Lead Brass), CDA 360 provides better machinability thanks to its lead content but offers slightly lower strength.

The 3% lead content in CDA 360 acts as an internal lubricant during machining, resulting in excellent chip breaking, reduced tool wear, and superior surface finish compared to low-lead alternatives. This translates to components with exceptional dimensional precision, surface quality, and cost-effectiveness. However, for applications requiring direct food contact or subject to stringent lead restrictions, lead-free alternatives like C69300 might be necessary, although they typically result in higher machining costs and potentially lower precision.

Q2: Are your CDA 360 Brass components compliant with RoHS and other environmental regulations?

A2: Our standard CDA 360 Brass (C36000) components contain approximately 3% lead, which exceeds the 0.1% threshold established by RoHS (Restriction of Hazardous Substances) directives. However, we offer multiple solutions for environmentally regulated applications:

For applications requiring RoHS compliance, we manufacture components using alternative alloys such as C69300 (ECO BRASS®), which maintains excellent machinability while eliminating lead content. These lead-free alternatives typically result in a 15-25% cost premium due to higher material costs, increased tool wear, and longer cycle times.

For components requiring partial RoHS compliance with exemptions (such as those covered under Annex III exemption 6c for copper alloys containing up to 4% lead by weight), we provide proper documentation verifying applicable exemption status.

All our manufacturing processes comply with environmental regulations regarding waste management, recycling, and sustainable practices. We maintain detailed material certification and traceability documentation to support compliance verification for regulated applications.

Q3: What tolerances can you maintain on CDA 360 Brass components, and how do these compare to other materials?

A3: CDA 360 Brass enables exceptionally tight tolerances compared to many other materials due to its superior machinability, minimal tool deflection during cutting, and excellent dimensional stability. Our standard manufacturing capabilities for CDA 360 Brass include:

External diameter tolerances of ±0.025mm (±0.001″) for dimensions up to 50mm, with capability for precision tolerances to ±0.010mm (±0.0004″) for critical features. Internal diameter tolerances of ±0.038mm (±0.0015″) for holes up to 25mm diameter, with capability for precision tolerances to ±0.015mm (±0.0006″) when required.

These tolerances are significantly tighter than what is typically achievable with materials like aluminum (usually requiring ±0.050mm or looser) or stainless steel (typically ±0.075mm) at comparable production costs. The excellent chip formation characteristics of CDA 360 Brass allow for better surface finishes as well, typically 1.6μm Ra or better without additional finishing operations.

The material’s stability and minimal internal stress result in excellent geometric tolerances, including roundness and straightness values typically within 0.025mm even for longer components, without secondary stress-relief treatments that might be necessary for other materials.

Q4: How does the lead content in CDA 360 Brass affect its applications, particularly for components used in water systems?

A4: The 3% lead content in CDA 360 Brass (C36000) provides significant manufacturing advantages, particularly regarding machinability, but does create limitations for certain applications:

For potable water applications in many jurisdictions, components must comply with regulations like the U.S. Safe Drinking Water Act, which limits lead content to a weighted average of 0.25% in surfaces that contact drinking water. Standard CDA 360 Brass exceeds this limit, making it unsuitable for such applications without secondary treatments or coatings.

For water system components that do not have direct drinking water contact or are used in industrial/non-potable systems, CDA 360 Brass remains an excellent material choice due to its combination of corrosion resistance, strength, and precision manufacturing capabilities.

For applications requiring both excellent machinability and potable water compliance, we offer alternative solutions including machining from low-lead alloys like C69300 (ECO BRASS®), utilizing bismuth-containing alloys like C89833, or applying compliant barrier coatings to CDA 360 Brass components where permitted by regulations.

It’s important to note that while the lead content limits CDA 360 Brass in direct drinking water applications, it does not affect its performance in most other fluid handling systems, including closed-loop water systems, industrial fluids, oils, and fuel systems.

Q5: What is the corrosion resistance of CDA 360 Brass, and how does it perform in different environments?

A5: CDA 360 Brass demonstrates good overall corrosion resistance, though its performance varies significantly across different environments:

In standard indoor atmospheric conditions, CDA 360 Brass shows excellent corrosion resistance with minimal surface degradation over many years of service. The material typically forms a thin, protective oxide layer that inhibits further corrosion.

In outdoor atmospheric exposure, the material develops a natural patina that provides additional protection, though the appearance will gradually darken from bright gold to a deeper brown. This patination process does not significantly compromise structural integrity for most applications.

In freshwater exposure, CDA 360 Brass performs well with corrosion rates typically less than 0.025mm/year (1 mil/year). However, in waters with high chloride content or acidic pH, dezincification may occur over time, particularly in stagnant conditions.

The material shows moderate resistance to many chemicals, performing well with aliphatic hydrocarbons, alcohols, and neutral solutions, but may experience accelerated corrosion in strong acids, ammonia compounds, and certain sulfur-containing environments.

For marine environments with saltwater exposure, standard CDA 360 Brass is generally not recommended without protective coatings due to susceptibility to dezincification. For such applications, we typically recommend alternative alloys like C44300 (Admiralty Brass) or C46400 (Naval Brass) which offer enhanced seawater resistance.

Q6: What is your standard lead time for CDA 360 Brass components, and what options are available for expedited production?

A6: Our standard manufacturing lead times for CDA 360 Brass components vary based on complexity, quantity, and current production schedules:

For standard catalog components, we typically maintain 2-3 week lead times from order confirmation to shipment. For custom components requiring new programming and tooling, standard lead time is 4-6 weeks, which includes design review, program development, tooling preparation, and production.

We offer several expedited production options for time-critical requirements. Our Quick Response Manufacturing (QRM) program can reduce lead times to 1-2 weeks for qualifying components with a 25% expediting premium. For emergency requirements, our Rapid Response program offers lead times as short as 3-5 business days for simple components or small quantities, subject to a 50% expediting premium.

For customers with recurring requirements, we offer Just-In-Time (JIT) delivery programs and blanket order arrangements that maintain inventory at our facility for release as needed, effectively reducing lead time to 24-48 hours for scheduled deliveries.

Lead time efficiency is achieved through our vertical integration, including in-house material inventory, tooling fabrication capabilities, and comprehensive machining and finishing operations, eliminating dependencies on external suppliers for most production steps.

Q7: What quality control measures do you employ for CDA 360 Brass components, and what documentation is provided?

A7: Our comprehensive quality control system for CDA 360 Brass components incorporates multiple verification stages:

Raw material verification includes spectrographic analysis to confirm alloy composition, hardness testing to verify mechanical properties, and dimensional inspection of incoming bar stock. During production, we implement Statistical Process Control (SPC) with scheduled in-process inspections, tool wear monitoring, and first-article inspection before production runs.

Final inspection includes dimensional verification using precision measuring equipment (CMM, micrometers, gauges), surface finish assessment using calibrated roughness testers, visual inspection under controlled lighting, and specialized testing for threaded features, geometric tolerances, and functional attributes.

Standard quality documentation provided with shipments includes Certificate of Conformance confirming specification compliance, material certification with chemical composition and mechanical properties, and inspection reports for critical dimensions. For customers with specific requirements, we offer enhanced documentation including PPAP (Production Part Approval Process) packages, ISIR (Initial Sample Inspection Report), material traceability documentation, and specialized test reports.

Our quality management system is certified to ISO 9001:2015 standards, with additional capabilities for industry-specific requirements including aerospace, automotive, and medical component traceability.

Q8: How do your CDA 360 Brass components compare to those made from alternative materials like stainless steel or aluminum?

A8: CDA 360 Brass components offer several distinct advantages and limitations compared to alternative materials like stainless steel or aluminum:

Compared to stainless steel, CDA 360 Brass offers superior machinability (typically 5-7 times faster machining speeds), resulting in significantly lower production costs for complex components. Brass provides better thermal and electrical conductivity than stainless steel, though with lower corrosion resistance in certain environments and approximately 20-30% lower tensile strength.

Compared to aluminum, CDA 360 Brass provides greater hardness and wear resistance, better thread strength, and superior stability for precision components. While aluminum is approximately one-third the weight of brass and offers better corrosion resistance in certain environments, brass components typically provide better long-term dimensional stability and are less susceptible to galling or thread damage.

For electrical applications, CDA 360 Brass offers electrical conductivity approximately 70% better than stainless steel but only about 40% that of pure aluminum. However, the superior machining characteristics of brass often allow for thinner wall sections and more complex geometries that can partially offset this difference for some applications.

The material selection ultimately depends on specific application requirements, with CDA 360 Brass typically being the preferred choice when machinability, dimensional precision, moderate strength, and good electrical properties are prioritized over weight or maximum corrosion resistance.

Q9: Do you offer secondary operations like plating, heat treatment, or surface finishing for CDA 360 Brass components?

A9: Yes, we provide comprehensive secondary operations for CDA 360 Brass components to enhance performance, appearance, and functionality:

Surface finishes include natural machined finish, uniform matte finish through media blasting or tumbling, and high-polish mirror finish through multi-stage polishing processes. For enhanced appearance and corrosion protection, we offer nickel plating in various thicknesses, decorative chrome plating, gold plating, and clear protective lacquer coatings.

Surface treatments include chemical passivation for enhanced corrosion resistance, black oxide for a darkened appearance, and anti-tarnish treatments for long-term appearance stability. Heat treatment options for Brass components include stress relief treatments to enhance dimensional stability for precision components and annealing for improved ductility when required.

Special surface enhancements available include laser marking for permanent identification, custom color anodizing over nickel plating for decorative applications, and specialized coatings for enhanced lubricity, wear resistance, or chemical resistance.

All secondary operations are performed either in-house or through our network of qualified and audited specialty processors, with comprehensive quality verification to ensure consistent results. We maintain detailed process specifications and quality requirements for all secondary operations, ensuring consistent performance across production lots.

Q10: What options are available for prototype development and small-quantity production of CDA 360 Brass components?

A10: We offer specialized services for prototype development and small-quantity production to support new product development, validation testing, and low-volume applications:

Our Rapid Prototype service provides quick-turn manufacturing of sample components in quantities of 1-25 pieces, with typical lead times of 5-10 business days depending on complexity. This service includes expedited programming, dedicated machine time, and comprehensive inspection reports.

For design validation, we offer Design Iteration packages that include multiple prototype versions with systematic design variations to evaluate performance characteristics and optimize final designs. This approach is particularly valuable for components with critical tolerances, specialized features, or challenging performance requirements.

Our technical team collaborates with customers to refine designs for optimal performance, manufacturability, and economic production.

Q11: How do you ensure consistent quality across large production runs of CDA 360 Brass components?

A11: Maintaining consistent quality across large production runs involves several integrated approaches:

Our Statistical Process Control (SPC) system monitors critical dimensions throughout production, utilizing automated measurement systems and control charts to detect trends before they result in out-of-specification components. Process capability studies (Cp/Cpk analysis) are conducted for critical features to ensure processes are centered and capable of maintaining specifications throughout production.

Tool management protocols include scheduled tool replacement based on wear monitoring, offset adjustments to compensate for tool wear, and duplicate tooling with identical geometries to maintain consistency during tool changes. Machine capability verification ensures that equipment maintains required precision, with regular calibration and preventive maintenance to prevent drift or capability degradation.

Material consistency is ensured through batch testing of raw materials, dedicated material allotments for large productions, and material traceability throughout the manufacturing process. Environmental controls in the production facility maintain stable temperature and humidity conditions to minimize thermal expansion effects and other environmental variables.

Comprehensive operator training and standardized work instructions ensure consistent execution of all production steps, while automated processes minimize operator-to-operator variation. For very large production runs, we implement dedicated production cells with equipment and tooling reserved exclusively for the specific component to eliminate setup variations.
