C17510 Beryllium Copper RWMA Class 3 has high thermal conductivity combined with good hardness and high-temperature strength. This alloy is being chosen with increasing frequency for applications requiring a combination of high electrical conductivity and mechanical strength, and for applications requiring wear and corrosion resistance. Alloy C17510 Class III beryllium copper is specifically recommended for projection welding dies, flash and butt welding dies, current carrying shafts and bushings. Class III alloy (having higher strength than class II), is recommended for highly stressed welder structural current carrying members and heavy-duty offset electrode holders. Class III alloy is generally recommended for spot welding and seam welding wheels having high electrical resistance, such as stainless steels. C17510 Beryllium Copper conforms to specifications ASTM B441 (ROD), ASTM B534 (PLATE) , RWMA Class III
