C93200 Tin Bronze Casting
C93200 Tin Bronze Casting (UNS C93200), commonly known as SAE 660 Bearing Bronze, contains nominally 83% copper, 7% tin, 7% lead, and 3% zinc. It is the most widely used bearing bronze in the world, offering excellent anti-friction properties, good machinability, and moderate strength. Indicative price: US$ 9.00/kilogram (subject to quantity and specification).
