Merit
C17200 provides the highest strength of any copper alloy,with electrical conductivity considerably greater than other high-strength copper alloys. Since it is heat treated after forming, it provides excellent formability and ductility. This alloy features good stress relaxation resistance and high fatigue strength.
Applications
connectors, burn-in sockets, test sockets,switch part, relay parts, motors, thermostats, EMI shielding shrapnel.
