The silicon bronzes are the most popular of the basic bronze families. These alloys have good strength and toughness. Coupled with their corrosion resistance and non-magnetic properties, these alloys are ideally suited for naval construction, particularly mine sweepers. Cold formed silicon bronze fasteners should be stress relieved to reduce the risk of stress corrosion failure.
- Silicon Bronze Alloy No. 651 (98.5% Cu, 1.5% Si) is best for cold headed parts
- Silicon Bronze Alloy No. 655 (97% Cu, 3% Si) for fasteners which must be made hot
- Silicon Bronze Alloy 661 (95% Cu, 3% Si, 0.5% Pb) for parts requiring machining
Industries we serve that use Silicon Bronze:
- Marine & Naval Construction
- Power & Energy
