C65100 Low Silicon Bronze "B"
C65100 Low Silicon Bronze “B” is an engineering alloy resistant to corrosion as copper itself, but much stronger, and with good fatigue endurance. The alloy is appreciated for its brazing ability, strength, corrosion resistance and electrical properties and serves as one of the most weldable copper alloys. The alloy can be joined by using resistance welding, soldering or brazing. The alloy is joined by gas shield arc welding, spot welding and also by oxyacetylene welding.
