Alloy 937 Bearing Bronze

Sequoia Brass & Copper sells alloy 937 bearing tin bronze. The high leaded tin bronzes contain the most widely used bearing bronze alloy C932 (also known as SAE 660). Lead weakens these alloys but imparts the ability to tolerate interrupted lubrication. It also combines favorable antifriction properties with good load-carrying capacities and will conform to slight shaft misalignment's.

This cast bronze has excellent machining properties and good corrosion resistance. Common fabrication processes include casting, soldering, and brazing with excellent wear resistance. 937 tin bronze can withstand mild acids in mine water, making it ideal for marine and industrial projects. 937 tin bronze comes in sand cast plate, solid bar, and cored bar and is cut to order with your specifications.
