Tin Bronze

At Saru Copper, we manufacture and supply a comprehensive range of tin bronze alloys, including PB1, PB2, and CT1, conforming to international standards like BS 1400, ASTM B505, and DIN 1705. Backed by advanced continuous casting technology and decades of metallurgical expertise, our tin bronze products are known for their excellent corrosion resistance, superior wear resistance, and low friction coefficient against steel.

Our tin bronze rods, bars, castings, and components are manufactured in compliance with global quality norms and are widely used across marine, automotive, engineering, and heavy machinery industries.
