C17410 (Alloy 174)
UNS.C17410 (CDA 174) Alloy 174 Copper Beryllium strip is a mill hardened alloy designed for use in the automotive, appliance and telecommunication markets.
It provides high yield and fatigue strength with high electrical conductivity and good resistance to stress relaxation.
In addition, it is also suitable for high temperature applications. C17410 copper beryllium strips features twice the electrical conductivity of normal brass, and it has a higher repetitive cycle life, and it can be easily formed into complex shapes, and it is also available with tin coatings or precious metal inlays.
