常见问题

When should I choose CCS-40% over CCS-30%?

Choose CCS-40% when higher conductivity is critical, such as in power connectors, high-current applications, or when lower resistance is required. CCS-40% provides better current-carrying capacity while still maintaining the strength advantages of the steel core.

What applications benefit most from CCS-40%?

CCS-40% is ideal for electrical connectors requiring both strength and conductivity, spring contacts, specialty cables with higher current requirements, and applications where the balance between conductivity and mechanical properties is critical.

How does CCS-40% compare to copper alloys?

CCS-40% offers similar or better strength than many copper alloys at lower cost. It provides 40% IACS conductivity with 400-600 MPa tensile strength, making it competitive with bronze and brass alloys while offering better cost-performance ratio.

Does higher copper content affect the strength?

Yes, CCS-40% has slightly lower tensile strength (400-600 MPa) compared to CCS-30% (500-700 MPa) due to higher copper content. However, it still significantly exceeds solid copper (~200 MPa) and provides adequate strength for most applications.
