bronze

Bronze metal is available in a wide range of alloys for purposes varying from bearings to architecture and marine applications. In general bronze is a great choice for strength, corrosion resistance and electrical conductivity. Bronze is primarily an alloy of copper and tin, but can also be made with other additives, such as aluminum.

Our bronze materials are available in various shapes and alloys, which can be custom-cut in just the amount you need.

bronze in various shapes and sizes:

C932 / SAE 660 - Bearing Bronze	(available in HollowBar, Round)
C954 - Aluminum Bronze	(available in HollowBar, Rectangle, Round, Square)
C655 - Silicon Bronze	(available in Round)
C863 - Manganese Bronze	(available in HollowBar, Round)

 

Bearing Bronze As the name implies, this is the most commonly used bronze in bushing and bearing applications. It is comparably easy to machine, and provides long life in applications where wear is a consideration.

 

Bearing Bronze (C932), a/k/a SAE 660
Minimum Properties	Ultimate Tensile Strength, psi	35,000
	Yield Strength, psi	20,000
	Elongation in 2"	10%
	Brinell Hardness	65
Chemistry	Copper (Cu)	81.0 - 85.0%
	Tin (Sn)	6.3 - 7.5%
	Lead	6.0 - 8.0%
	Zinc	2.0 - 4.0%

 

Aluminum Bronze Aluminum bronzes are most valued for their higher strength and corrosion resistance as compared to other bronze alloys. These alloys are tarnish-resistant and show low rates of corrosion in atmospheric conditions, low oxidation rates at high temperatures, and low reactivity with sulfurous compounds and other exhaust products of combustion. They are also resistant to corrosion in sea water. Finally, they prevent colonization by marine organisms including algae, barnacles, and mussels.

Aluminum bronzes are most commonly used in applications where their resistance to corrosion makes them preferable to other engineering materials.

Aluminum Bronze, C954
Minimum Properties	Ultimate Tensile Strength, psi	85,000
	Yield Strength, psi	32,000
	Elongation in 2"	12%
	Brinell Hardness	170
Chemistry	Copper (Cu)	83.0% min
	Iron (Fe)	3.0 - 5.0%
	Aluminum (Al)	10.0 - 11.5%

 

Silicon Bronze Silicon Bronze is a high-strength, highly corrosion resistant material with nonmagnetic properties. It is generally as strong as steel. Because of its composition, it is more difficult to machine. However, it is excellent for use in general marine applications, as well as pumps and boilers.
