Copper Casting Methods Used
We use advanced casting techniques to produce high-quality copper components with excellent density, conductivity, and mechanical properties.
1. Permanent Mold Casting (Gravity Die Casting)
- Produces dense, high-precision copper castings.
- Ideal for complex shapes and repeatable production.
- Best for electrical and industrial applications.
2. Sand Casting of Copper
- Used for larger components and custom-shaped parts.
- Cost-effective for low to medium production runs.
- Best for busbars, transformer components, and industrial fittings.
3. Copper Centrifugal Casting
- Ideal for cylindrical components such as bushings, sleeves, and motor rotors.
- Ensures high mechanical strength and defect-free surfaces.
4. Investment Casting (Lost Wax Casting) of Copper
- Used for intricate and precision components.
- Produces fine details with minimal machining required.
We recommend the best casting method based on component design, conductivity requirements, and cost-effectiveness.
Typical Conductivity of Our Copper Castings
- Oxygen-Free Copper (OFHC β C10100): 101% IACS (Highest electrical conductivity available).
- ETP Copper (C11000): 98-101% IACS (Most commonly used for electrical applications).
