CDA651 (C65100)	Low-silicon bronze B			CDA651 standards and properties

CDA651 (C65100) Low-silicon bronze B is an engineering alloy at least as resistant to corrosion as copper itself,
but much stronger, and with good fatigue endurance. It is an alloy noted for its brazeability, strength, corrosion resistance, and electrical properties. CDA651 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.




CDA651 finds its broadest use as rod and wire for cold headed and roll threaded bolts, wood screws and lag screws. CDA651 wood screws and lag screws have unusually high strength and toughness, freedom from embrittlement, and a high degree of corrosion resistance to all types of water, saline fogs, and a wide variety of other corrosives.



CDA651 hull and deck fastenings are the standard materials with yacht designers and the majority of builders of stock power boats. The alloy is also used for cable connectors, mast tangs, deck and pilot house hardware and equipment, welded fuel and water tanks for pleasure and commercial crafts. It is also one of the best copper alloys for pole line hardware.




CDA651 nails are also widely used in boat construction and for nailing slate, heavy tile, and other materials where strength and corrosion resistance are essential
