Abstract:
An alloy of copper with other elements like Tin & Phosphours is called phosphor bronzes generally phosphor
bronze contains Tin up to 10-12% and Phosphorus up to 0.3% apart from copper & other elements. Addition of
Phisohorus improves foundry properties raises hardness, strength elastic properties & specially corrosion
resistance and anti friction properties which makes it suitable & making bushes where antifriction properties
alongwith strength are required. Phosphor Bronze Bushes have wide applications in engineering marine &
automobile industries.
