LEAD-FREE | LOW-LEAD
Tin bronze alloys, such as C90800, are typically found in gear, high-strength bushing and bearing
applications where low speeds and heavy loads are present. Other high-strength applications for these
alloys include pump impellers, piston rings, steam fittings and valve bodies. C908 tin bronze castings are
utilized in movable bridge components, turntables for bridges and other structures for fixed and expansion
bearings with slow or intermittent movement with heavy loads.
