UNS C93700 Tin Bronze Chemical Composition, Grades, Tables and PDF Online

UNS C93700 Tin Bronze is an alloy commonly used it contains copper, tin and some other minor quantities. Chemical composition of this ore material averagely contains about 85% copper and 10% tin, with the remaining limitation from small quantities of their zinc, phosphorus and lead. The present alloy provides remarkable machinability, wear-resistance as well as corrosion-resistance, what makes the alloy suitable for all kinds of applications such as bearings, bushings, gears, and valve components. The constituents of UNS C93700 may vary slightly according to the corresponding grades to match up the needs for the applications. Comprehensive charts showing chemical composition of different grades and mechanical properties for reference by engineers, manufacturers, and grade specifiers can be found online. A PDF document with complete details on the alloy UNS C93700 Tin Bronze is available for users who can look it up and use to their advantage.

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.
