4mm Copper Nickel Silicon Alloy C7025 Copper Strip


Standard: JIS C7025, UNS C70250

Alloy C7025 is a High Performance Alloy that combines strength, conductivity, formability and stress relaxation resistance into a unique set of properties. 

C7025 has the qualities of some of the Beryllium Coppers without containing any Beryllium. The alloy is a thermally aged material. It achieves it’s properties 

by combinations of cold work and heat treatments, all of which is done at the mill. The alloy’s high strength and conductivity combined with its formability 

and stress relaxation properties make C7025 an excellent electronic alloy, particularly in high temperature environments.
