C95900 Aluminum Bronze

C95900 Aluminum Bronze is characterized by its high strength and excellent corrosion resistance. Uses for the alloy include a variety of heavy duty mechanical and structural products including gears, worm drives, valve guides and seats. C95900 is an excellent heavy duty bearing alloy, but does not tolerate misalignment or dirty lubricants and generally should be used against hardened steel shafts, with both shaft and bearing machined to fine surface finishes.

Typical Applications


Gears, worm drives
