Phosphor Bronze
OVERVIEW
Phosphor bronze combines good strength with high fatigue resistance without having to compromise on its machinability. Phosphor Bronze can resist pounding very well and has good corrosion resistance especially against seawater. Phosphor Bronze has the lowest coefficient of friction among bronze alloys therefore runs cooler against hard steel shafts and has good resistance to wear and abrasion
