UNS C93800 Tin Bronze Chemical Composition & Properties, Grades, Table and Document

UNS C93800 Tin Bronze is a high performance material which has been the first choice among the designers and engineers due to its overall alloy characteristics such as strength, corrosion resistance and machinability. Often you encounter a mixture consisting of copper, tin and tiny specks of other ingredients; those might be phosphorus and zinc. Alloy bronze is commonly employed for services needing exceptional wear resistance, good casting qualities, and burring arrests to varying degrees: as bushings, bearings, gears, and valves. The UNS C93800 designation may include grades with compositions that vary slightly to meet different specifications. The features that the metal UNS C93800 Tin Bronze possesses is that it has high level of tensile strength, excellent machinability and at the same time its corrosion resistant in a variety of condition. Engineers and manufacturers commonly make use of specialized tables and chart with specified material and composition lists that provide detailed information for accurate application purposes.

UNS C93800 Tin Bronze Chemical Composition And Grade Table

UNS C93800, known as Tin Bronze, and which is one of the alloy family preferred for its best machinability and corrosion resistance. Consisting of copper and tin, with traces of lead, zinc and phosphorus, its chemical composition gives the material increased mechanical properties and improved heat conductivity. This alloy is widely used under sea water, in electrical devices, and in machine parts parts, largely because of its corrosion resistance and low friction. This grading system has been materialized and any user can see the variations in the composition and performance. Thus, it has a broad range of applications in industries that require durable materials.
