An American continuous cast low alloy aluminium bronze containing an addition of iron CuAl9Fe3 (9A). The iron acts as a grain refiner and gives added strength. The alloy is medium strength and has good corrosion resistance in sea water. The alloy can be manufactured to several Internation specifications, SAE J461/ J462, SAE 68a, QQ-C-390B G6, QQ-B-671 Class 1, Mil-B-16033 Cl 1, Mil-C-22229, BS 1400 AB1, JIS H 5121 CAC 701C Class1, EN 1982-2008 CC331G, DIN 1714 W Nr 2.0940.03, AS 1565 C95210, GB 1176 ZCuAl10Fe-La, NF A53-709 CuAl10Fe3 Y70, SIS 145710 and GOST 493 BrA9Z3L-Ka.
