C90700/CuSn10

Characteristic
This alloy is recommended for high static loads. The high tin content and the phosphorus addition impart to the alloy excellent wear resistance, fatigue strength, and bearing properties. The most commonly used wrought forms are strip and wire. The other areas of usage are bearing, gearboxes, valve bodies, and worm gears.
