Application

UNS.C17500 Beryllium Copper Alloy 3

Beryllium copper alloy C17500 is heat-treatable with moderate electrical and thermal conductivity and high tensile strength. 
It is recommended for projection welding dies, flash and butt welding dies, current-carrying members, and heavy-duty offset electrode holders. It is also generally recommended for spot and steam welding steels with high electrical resistance, such as stainless steel.
It provide a good strength with even better thermal conductivity than C17200.This alloy offers conductivity of 45 to 60 percent of pure copper while providing significant strength and hardness properties.
