Material with CDA numbers less than C80000 are considered either a wrought brass or bronze alloy. Wrought alloys are first cast, then physically worked to obtain their shape, usually by the extrusion process. Due to the reduction in area of the material, wrought alloys typically have increased strength, hardness and stiffness as compared to their cast equivalents. Wrought products include: rods, bars, tubes, sheets, plates and wires.
C64200 is an engineering alloy at least as resistant to corrosion as copper itself, but much stronger. It is considered to be of the best valve stem alloys.
C31400 Leaded Commercial Bronze is a free machining alloy with excellent electrical and thermal conductivity. Corrosion resistant. Typical applications include door knobs, electrical connectors, nuts, screws, pickling crates and fixtures.
C63000 Aluminum Bronze is a high strength copper aluminum alloy, containing 81% copper, 10% aluminum, 5% nickel, 4% iron, and an excellent choice for applications involving heavy loads, abrasive wear resistant, friction, abrasive wear and corrosion. The addition of nickel increases the alloys strength without diminishing its excellent ductility, toughness and corrosion resistance.
C51000 Phosphor Bronze, is the most widely used of the phosphor bronze alloys. C51000 offers high strength and ductility, superior fatigue and spring characteristics, excellent corrosion resistance, durability for severe service, good bearing qualities with low friction and higher wear resistance, superior forming and spinning, resistance to stress relaxation and good joining properties.
C54400 Phosphor Bronze is an excellent bearing alloy, and exhibits very good machinability due to its lead content. The alloy has excellent spring properties, and is used for electrical contacts, and can be work-hardened. When annealed, this metal can be bent, formed, blanked, and stamped.
