CC333G
A cast nickel aluminium bronze with 10% aluminium and 5% of nickel and iron. The alloy conforms to BS EN 1982-2008 CC333G CuAl10Fe5Ni5-C and can be specified to BS 1400 AB2 CuAl10Fe5Ni5. Alloy CC333G has excellent wear and anti-galling properties when running against stainless steels and most other grades of nickel and iron based alloys. CC333G has also outstanding corrosion/erosion/impingement resistance in flowing sea water up to 4.5m/sec and can used for boiler water handling systems or sea water cooling systems. The alloys can tolerate high loads but as this is a cast alloy, and therefore of low integrity, is generally restricted to slow moving parts with good lubrication. For engineers interested in high-integrity material, for more critical applications, it is suggested that the hot worked version of this alloy is considered - CW307G.
