UNS C90300 Tin Bronze Chemical Composition & Properties, Grades, Chart and PDF Online

UNS C90300, holding the name in even contests with Tin Bronze, is the copper alloy mostly known for its excellent corrosion resistance and machinability potential. Its chemical structure includes copper (Cu) as a major component, with tin (Sn) being the most significant alloying element. In addition, these items contain other elements that are present merely in a minute amount to improve specific characteristics. Specifically, tin bronze has advantages in mechanical property, which has resulted in wide range of applications such as bearings, bushings, pump components, valve fittings and others. Generally, it is grade separated according to the tin content, with the higher tin content grades providing more strength and wear resistance. Comprehensive charts and PDF resources that manufacturers can easily access online are relied on by engineers to obtain highly detailed information about the composition, properties, and grades of Tin Bronze for informed decision-making while selecting materials and application.

UNS C90300 Tin Bronze Chemical Composition And Grade Table

UNS C90300 specified as Tin Bronze is popular for its high machinability, great corrosion resistance, and good wear resistance. Comprised of copper that has tin as the main alloying part, it usually contains around a 88% – 91% amount of copper with a 7% to 9% portion of tin and with traces of lead, phosphorus, and zinc. Composition of such materials is highly remarkable when it comes to mechanical properties that led to its suitability for uses like bearings, bushings, gears, and valves. Its specifications and grade are totally subject to its quality table which assures the same degree of consistency and reliability for its performance in various industrial applications.
