A family of different bronze alloys that account for most of the nonferrous gear materials, mainly because of their "wear resistance" characteristics for withstanding a high sliding velocity with a steel worm gear. High Tin bronze alloys are typically found in gear, high strength bushing and bearing applications where high strength and low speeds and heavy loads are present. Other high strength applications for these alloys are pump impellers, piston rings, steam fittings, valve bodies. High tin bronze castings utilized in movable bridge components, turntables for bridges and other structures for fixed and expansion bearings with slow or intermittent movement with heavy loads.

Hard, strong alloy with good corrosion resistance, especially against seawater. As bearings, they are wear resistant and resist pounding well. They possess excellent rubbing characteristics and wear resistance which permits use in gears and worm wheels for severe wear applications.
Offers good mechanical and corrosion resistance; it's often used in castings for liquid and gas, not to mention valves and pumps. In addition to the many qualities C903 possesses, it offers a high wear resistance making it an ideal candidate to many jobs.
Hard strong alloy with good corrosion resistant properties. Ideal for applications with heavy loads and low speeds. Material is wear and impact resistant. It is difficult to broach, but can be reamed or bored.
