UNS C90700 Tin Bronze Chemical Composition, Grade, Chart and Document

C90700 UNS is a tin bronze alloy famed for its unusually high machinability and corrosion resistance. Copper was the main component of alloy, with tin being the additional metal of the mixture. Some trace amounts of other elements are also added to further improve its properties. This alloy is composed of 88% of copper, 10% of tin, and about 2% of zinc and hence this alloy is resistant to wear, has got a high strength and an excellent castability which makes it to be used for applications like bearings, bushings, gears, and fittings. The chemical composition services for near perfect thermal and electrical conductivity as is the case with corrosion, tarnishing and dezincification. Manufacturers follows the standardized charts and documentations to provide the consistency and quality of production process through the abidance of the standard requirements of the tin bronze grade material.

UNS C90700 Tin Bronze Chemical Composition And Grade Table

UNS C90700, a variety of copper alloy often called Tin Bronze, is recognized for its outstanding anticorrosion capacity and processing features. This chemical composition usually has copper (Cu) as the basis with tin (Sn) being the major alloying element present. Besides, these compounds can also include amounts of elements such as zinc (Zn), lead (Pb), and phosphorus (P) in some minor form. Along with them, these compounds produce properties that are unique. Tin Bronze formulates to different qualities primarily through its tailored compositions, thus proving its availability in various applications. Its formulation complies with the industry standards, which sustains its performance and durability in the involving engineering or manufacturing processes.
