CuSi3Mn-UNS. C65500 Silicon Bronze Alloys, which is high strength, engineering alloys have excellent resistance to a wide range of corrosives, including fresh and salt water, most acids, alkalis, salts, and organic chemicals. However, thery are not suitable for use with sulfides, nitric and acid chromates, or oxidizing salts such as ferric chloride. It has a combination of corrosion resistance, strength, resilience, and formability that makes them among the most widely used copper alloys. They are also noted to be non-sparking, galling resistant, and fatigue resistant. C65500 is nominally composed of 95.8% copper, 3.3% silicon, and 0.9% manganese, so the typical applications of C66550 include electrical conduit, pump shafts, valve stems, tie rods, fasteners, marine and pole-line hardware, nuts, bolts, srews, rivets, nails, bushings, screen cloth and wire.

Typical Application for C65500 Silicon Bronze Alloys:

Aircraft: Hydraulic Pressure Lines

Electrical: Pole Line Hardware, Motors, Rotor Bar

Fasteners: Scerws Cloth, Wear Plates, Screen Plates, Shafting, Wire, Welded Pressure Vessels, Oil Refinery Plumbing Tube, Bearing Plates, Butts, Bushings, Cable, Channels, Chemical Equipment, Heat Exchanger Tubes, Kettles, Hydraulic Pressure Lines, Tanks, Piston Rings, Doctor Blades, Paper Industry, Pressure Vessels, Welded Tanks

Marine: Propeller Shafts
