Description
SAE660 Round Bar
SAE660 Round Bar is Leaded Bronze Grade which 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. C932 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 C93200 is strictly controlled as are the casting conditions.
SAE660 leaded bronze is suitable for various engineering applications performed under medium loads whilst using adequate lubrication.
The alloy is a continuously cast leaded copper-based material known as leaded bronze. It is highly suited to pump and valve component manufacture due to the alloy’s resistance to brine. SAE660 offers good sliding and dry-running properties and is not subject to dezincification. Our product also boasts excellent machinability characteristics.
