Phosphor Bronze Washers

Phosphor Bronzes, or tin bronzes, are alloys containing copper, tin and phosphorous. Phosphorous Bronze Fasteners, contain between 0.5 and 11% tin and 0.01 to 0.35 % phosphorous. Phosphorous Bronze Stud Bolts have superb spring qualities, high fatigue resistance, excellent formability and solderability, and high corrosion resistance. Phosphorous Bronze Fasteners  primarily used for electrical products, other uses include corrosion resistant bellows, diaphragms, and spring washers. 

Phosphorous Bronze Fasteners combine good strength and fatigue resistance with good machinability, high wear resistance and corrosion resistance. Phosphorous Bronze Fasteners have a wide freezing range and extensive segregation of the alloying occurs on cooling. Phosphor bronze which is often referred to as tin bronze or phos bronze is an alloy of copper, tin and phosphorous.
