An American continuous cast low alloy aluminium bronze CuAl11Fe4 (9C) containing an addition of 4% iron with the option of adding up to 1.5% of Nickel. This is a higher strength alloy that C95300/C95200 and has greater wear resistance with the higher level of iron. This alloy is one of the most popular general purpose bearing alloys of the aluminum bronzes family in the USA which can also be heat treated to enhance the properties (C94500HT). It also conforms to additional specifications SAE 68A, SAE J461/ J462, AMS 4870, AMS 4871, AMS 4635, QQ-C-390B G5 ,QQ-B-671 class 2, Mil-B-16033 class1, Mil-C-15345-13, BS1400 AB1, EN 1982-2008 CC331G,SFS 2211 GC CuAl10Fe3, DIN 1714 W Nr 2.0940.03, NS 16575, GB 1176 ZCuAl10Fe3-La and SIS 145710.
