UNS C93700 Tin Bronze Chemical Composition And Grade Table

UNS C93700, also known as Tin Bronze, is the combination of copper, tin and some other minor ingredients which is a type of bronze alloy. With a chemical composition that is 88-90% copper and 8-10% tin and minute amounts of phosphorus and other elements, it is the most widely used type of bronze. Such a structure results in good mechanical properties (high strength, wear resistance, corrosion resistance) and, thus, allows the manufacture of different kinds of components (bushings, bearings, gears, valve components, etc.) It complies with ASTM B505 standards and is specified under Grade 93700, a recognised mark for the reliable use in engineering systems.
