What is CC491K?
CC491K bronze is a bronze formulated for casting. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition. CC491K is the EN numeric designation for this material. CuSn5Zn5Pb5-C is the EN chemical designation. It has a fairly high electrical conductivity among cast bronzes.
What is naval bronze?
Naval Bronze is a copper alloy comprised of 85% copper, 5% Tin, 5% Lead, 5% Zinc (85-5-5-5) and a trace of other alloys. In addition, Tin gives the alloy a high resistance to corrosion and weakness. The higher tensile strength and resistance to cavitation make it an appropriate selection for seawater applications.
What is ASTM B62?
ASTM B62, 2017 Edition, April 1, 2017 – Standard Specification for Composition Bronze or Ounce Metal Castings. This specification2 establishes requirements for an alloy having a composition of copper, tin, lead, and zinc, used for component castings of valves, flanges, and fittings.
What is BS1400 LG2?
A British continuous cast leaded gunmetal to BS1400 LG2 CuSn5Zn5Pb5, which also meets the European norm BS EN 1982-2008 CC491K. This alloy has higher strength than CC490K and can be used under low mechanical loads and non-critical engineering applications.
Is gunmetal and bronze same?
Gun metal, also known as red brass in the United States, is a type of bronze; an alloy of copper, tin and zinc. Proportions vary but 88% copper, 8–10% tin, and 2–4% zinc is an approximation. Originally used chiefly for making guns, it has largely been replaced by steel for that purpose.
