The diameter can be customized from 20mm to 2000mm according to customer requirements, which is suitable for the production of various precision industrial components.

High-Performance Copper Grade Selection

The product is made of C1100, C1220, C11000, C12200, C10100, C10200 and C14500 high-purity copper grades. These materials have excellent electrical conductivity, thermal conductivity and machinability. C10200 features ultra-high purity and is suitable for precision electronic components; C14500 has good wear resistance and is applicable to mechanical processing parts, fully meeting the differentiated material needs of corporate clients.

Stable Temper & Strong Adaptability

Temper grades include O, 1/4H, 1/2H, 3/4H and H, which can be selected according to the processing technology (such as stamping, bending, welding) and application scenarios of copper circle. The stable temper ensures consistent product performance and reduces the defective rate of corporate production lines.

FAQ

What is the diameter customization range of your copper disc and how to confirm the mold parameters?

The diameter range is 20~2000mm, and customers only need to provide detailed technical drawings or mold parameters (such as inner diameter, outer diameter, thickness tolerance), and our professional technical team will confirm the production feasibility and provide optimization suggestions.

How is the copper circle packaged for international transportation and how to ensure product safety?

We use export wooden pallets for packaging, with anti-collision and anti-rust treatment inside the package, which can effectively prevent product damage and oxidation during long-distance transportation. For bulk orders, we can also customize packaging solutions according to customer requirements.

Can I choose different copper grades for the same size of precision copper disc for circuit breakers?

Yes, the same size of copper disc can be produced with different copper grades (such as C1100, C1220, C10200) according to your application needs (such as conductivity, high temperature resistance, machinability), and we will provide the corresponding material performance parameters for your reference.
