C17510 Beryllium Copper CL3 Rectangle Bar
In addition to being conductive, these 17510 beryllium copper bars are non-sparking and non-magnetic, so they’re used in mines and oil rigs, as well as for navigational tools. The beryllium and nickel in this alloy make it stronger and more rigid than pure copper, but not as conductive. These bars are conductive enough for electrical relays, probe pins, and test-socket and modular-jack contacts, while being strong enough for welding dies, plunger tips, and injection-mold nozzles. Even after collisions and frequent use, they maintain their shape, so they’re used for molds and cavities. Meeting RWMA Class 3, they’re recommended when seam and spot welding electrically-resistant material, such as stainless steel. They also withstand extreme temperatures and won’t rust outdoors. This material is produced to ASTM B441.

CDA/UNS
C17510 Beryllium Copper is specifically recommended for projection welding dies, flash and butt welding dies, current carrying shafts and bushings. Class 3 castings are recommended for welder components that carry current, and are under heavy load, including heavy duty offset electrode holders. Class 3 copper is generally recommended for spot welding and seam welding steels having high electrical resistance, such as stainless steels.
Typical Uses
Electrical Instrument parts, connectors, heavy duty relay parts, conductors, switch parts, fuse clips. Industrial Welding equipment parts, die casting plunger tips, high flux electromagnets, thermal transfer plates.
