ASTM C95520 / C95520HT

An American continuous cast nickel aluminum bronze CuAl11Fe5Ni5 primarily used for aerospace applications. This alloy has high strength which is produced by a quench and temper anneal which promotes excellent wear resistance and anti galling properties. This makes it an excellent choice for commercial and military landing gear bushings and bearings. The alloy also meets alternative International specifications, AMS 4881, EN 1982-2008 CC334G, AS 1565 C95810, JIS H 5120 CAC 703 Class 3, SFS 2212 GC CuAl10Fe5Ni5, NF A 53-709 CuAl10Fe5Ni5 Y70, DIN 1714 W Nr 2.0975.04 and GOST 493 BrA10Z4N4L-K.
