C19010

Standard

JIS DIN EN ASTM/UNS/CDA GB/T
C1901 CuNiSiP / C19010 /

Merit

C19010 is a precipitation-hardened copper alloy combining high electrical and thermal conductivity with elevated strength and good stress relaxation resistance.Due to the NiSi-precipitations the relaxation properties, even at temperatures up to 150 °C are excellent. Welding, soldering and brazing properties are good too.

 

Applications

Fisheye terminals, switches and relays, contacts, connectors, semiconductor components, junction boxes.
