C932 SAE 660 Leaded-Tin Bronze (Bearing Bronze)
ASTM B505, ASTM B271, SAE 660
Leaded Tin C932 Bearing Bronze is available from Farmer’s Copper Ltd. in rod form. Known as bearing bronze, C93200 has excellent machining properties, good hardness, as well as strength and wear resistance with excellent antifriction qualities. SAE 660 bronze has a long life span, making it an ideal alloy for bushing and bearing applications. C932 brings a machinability rating of 70, giving it a vast number of potential applications. Copper Alloy 932 is not subject to dezincification.
The bearing applications for Farmers’ Copper C932 Leaded Tin Bronze stretch across a range of industries, including aerospace, marine, and oil & gas.
Bearing components for aerospace applications require metals and alloys that are lightweight and have excellent corrosion resistance and the ability to maintain performance across a broad temperature range. C932 is a high strength alloy that will meet stringent wear resistance requirements.
C932’s high corrosion resistance also makes it a suitable alloy for marine applications. Farmers’ Copper C932 is the best choice for marine bearings capable of withstanding prolonged exposure to saltwater and pressurized environments.
Similarly, C932 can be utilized for high-pressure applications common to the oil & gas industry. C932 can be relied upon for bearings used for drilling equipment, pumps, and valves, resisting the high temperatures.
