Abstract
1527993 Copper alloy TOYO VALVE CO Ltd 1 Oct 1975 [6 May 1975] 40120/75 Heading C7A A high strength, easily castable corrosion resistant copper alloy, suitable for use as valves, cocks or other accessories in highly corrosive industrial fluids, in which dezincification and Al-removal by corrosion is significantly reduced contains: – Al 5 – 6À5 Si 0À2 – 0À5 Sn 0À2 – 0À5 Zn 0À2 – 4À0 Pb 1À0 – 1À5 Fe 1À0-3À0 Cu balance plus impurities. An addition of up to 0À17 Be may be made to improve the fluidity and reduce the oxide film tenacity during casting.
