COPPER ALLOY
DATA SHEET
C65500 and C66100
Everdur C65500 and C66100 are high strength, engineering alloys which have excellent resistance to a wide range of corrosives, including fresh and salt water, most acids, alkalies, salts, and organic chemicals. However, they are not suitable for use with sulfides, nitric acid, acid chromates, or oxidizing salts such as ferric chloride. Both alloys have 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, while C66100 is nominally composed of 95.4% copper, 3.1% silicon, 1.0% manganese, and 0.50% lead. The addition of lead to C66100 makes it more suitable for machining and for applications where machining is the primary fabrication process. It also makes C66100 less weldable than C65500.
Hot Working: C65500 has excellent hot workability and can be readily hot formed and pressed. The alloy is basically known for its hot working properties. Due to its lead content, hot working is not recommended for C66100.
Cold Working: C65500 and C66100 have excellent cold workability. However, they work-harden rapidly and should not be subjected to severe deformation in operations such as cold heading unless they are subsequently relief annealed to avoid the possibility of stress corrosion cracking.
Joining: C65500 is one of the most weldable copper alloys. It is readily joined by all types of resistance welding. Joining by soldering is good, while excellent by brazing. Joining by gas shielded arc welding and spot welding is excellent, and by oxyacetylene welding, good. The requirements of the ASME Boiler and Pressure Vessel Code for Unfired Pressure Vessels are readily met by inert-gas arc welding with filler metal of C65600. C66100 is not as weldable as C65500 due to its lead content.
Applications: 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 applications of C66100 include bushings and bearings.
Applicable Specifications: When so specified, C65500 and C66100 will be manufactured to the latest revision of the following specifications: ASTM B98 and B124 (C65500 only) for rod, bar, and shapes, and B99 (C65500) for wire.
Standard Forms Available: Rod, bar, wire (C65500 only), and extruded shapes.
