SAE660 932 Leaded Bronze
SAE 660 / C93200 Leaded Bronze is a general purpose leaded tin bronze bearing and bushing material. It has excellent machining properties, good hardness, strength and wear resistance with excellent anti-frictional qualities. The alloy is not subject to dezincification and has reasonable corrosion resistance to sea water and brine making it suitable for pump and valve components. 932 is suitable for bearings having medium loads and speeds with adequate lubrications. SAE 660 has very similar components to LG2 bronze albeit with slightly different proportions. This means that both metals can be used interchangeably in most cases.
The composition of 932 is strictly controlled as are the casting conditions. All Kormax bronze is manufactured using finely controlled continuous or centrifugal casting techniques to ensure that hardness and strength is superior to sand-casting methods. This also means that the material has a fine grain structure and is free from porosity.
