C63600
The C63600 Silicon Aluminum Bronze possess good hot and cold workability, forging ability. The alloy is fabricated by bending, coining, drawing and upsetting, hot forging and pressing, knurling, roll threading, shearing, spinning, swaging, and stamping.
Typical Uses :
- Electrical : Cold Headed Nuts, Cable Connectors, Components for Pole Line Hardware
- Fasteners : Screw Machine Products, Bolts
- Industrial : Valve Components, Nuclear Power Service
