Product Description

C932 Bronze | SAE 660 | C93200 (SAE 660) High Lead Tin Bearing Bronze is our most popular alloy.

C93200 Bronze is a general purpose bearing alloy possessing good anti-friction properties, ample strength and hardness, adequate ductility and excellent machinability. It is used as bearings, bushings, light duty gears and sprockets, impellers, wear strips, plates, automotive fittings and washers. It is used extensively in pumps, cylinders, machine tools, earth moving machinery and a myriad of general purpose applications.

Other terms for this alloy are: Bronze Bar, C 932, C932 Bronze, Bearing Bronze , SAE 660, SAE660, 932 Bronze Rounds, 932 Bronze Tubes, 932 Bronze Rectangles, Leaded Bronze, UNS 93200, Ingot # 315, Asarcon 773, CDA 93200, SAE J461; SAE J462, ASTM B-271 Alloy C93200, ASTM B-505 Alloy C93200, QQC-390 Alloy E7, Mil B-11553-12, 83-7-7-3.

Notice: The weights listed are the best estimates of the actual weights we will ship. They are a combination of the calculated theoretical weights and an average of actual weights. Our weights are conservative to the heavier side but there may be slight variations in weight from bar to bar.

The Physical, Fabrication and Thermal Properties shown here represent reasonable approximations suitable for general engineering use. Due to commercial variations in compositions and to manufacturing limitations, they should not be used for specification purposes.
