CuSi3Mn1 – UNS.C65500 Higher Silicon Bronze Alloys
C65500 Details & Applications:
C65500 Higher Silicon Bronze
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, they are not suitable for use with sulfides, nitric acid, 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 C65500 include electrical conduit, pump shafts, valve stems, tie rods, fasteners, marine and pole-line hardware, nuts, bolts, screws, rivets, nails, bushings, screen cloth and wire.
Typical Application for C65500 Silicon Bronze Alloys:
Aircraft: Hydraulic Pressure Lines
