C17510 Class 3 Beryllium Copper

Beryllium Copper Alloy

Class 3 C17510 is specifically recommended for projection welding dies, flash and butt welding dies, current carrying shafts, and bushings. Since they have higher strength than Class 2, C17510 is recommended for highly stressed welder structural current carrying members and heavy duty offset electrode holders.

Class 3 C17510 is generally recommended for spot welding and seam welding steels, such as stainless steel, since it has high electrical resistance. The C17510 Alloy is heat treatable.

The most common uses for C17510 are in those applications that need a lot of conductivity of temperature or electricity. Its ultimate tensile strength is 140 ksi while its hardness is RB 100. The conductivity of C17510 is about 45-60% of regular copper.
