C65100 Low Silicon Bronze "B"
Short Description:
C65100 is an engineering alloy at least as resistant to corrosion as copper itself, but much stronger, and with good fatigue endurance. 651 Bronze is an alloy noted for its brazeability, strength, corrosion resistance, and electrical properties. C65100 is one of the most weldable copper alloys. It is readily joined by all types of resistance welding. Joining by soldering or brazing is excellent. Joining by gas shielded arc welding and spot welding is also excellent, and by oxyacetylene welding, good.
