Silicon aluminum bronze combines the self lubricity of the silicon with the

higher mechanical properties of aluminum bronze and is sometimes used

in place of C63000 where specifications permit. C64200 is free-machining

and has good anti-galling and anti-seizing properties. Typical applications

involve valve stems, gears, marine and pole line hardware, wing pylons,

bolts, nuts, bushings and valve body components.

Landing Gear Parts, Strut Bushings

Rock Bit Bearing Bushings, Blowout Preventer Parts,

Wellhead Components

Valve Guides, Automobile Engine Cam Parts, Safety Belt
