Copper base alloy with 3.5 10 % of tin to which phosphorus has been added in a molten state in varying amounts of less than 1% for deoxidizing and strengthening purposes.

a corrosion-resistant bronze containing phosphorus; used in bearings and gears

This strong and relatively hard alloy is used to fabricate metal parts and springs. Phosphor bronze is resistant to corrosion.

An exotic alloy sometimes used in making springs.

A copper-tin phosphorous alloy, hard and strong.

See Copper Alloy.

Phosphor bronze is an alloy of copper with 3.5 to 10% of tin and a significant phosphorus content of up to 1%. The phosphorus is added as deoxidizing agent during melting. These alloys are notable for their toughness, strength, low coefficient of friction, and fine grain.
