We will also highlight the advantages of choosing our product and why it is the ideal choice for your business needs.
Composition
Our C90300 Tin Bronze is a copper alloy that contains up to 10% tin, 1% zinc, and 0.5% phosphorus. This alloy has a nominal composition of 88% copper, 10% tin, and 2% zinc, which gives it excellent strength, corrosion resistance, and wear resistance. The high tin content provides added strength and reduces the risk of stress corrosion cracking, while the phosphorus content improves its machinability.
Physical Properties
The C90300 Tin Bronze is a non-ferrous metal alloy that has excellent physical properties, such as high melting point, thermal conductivity, and electrical conductivity. Its melting point is 883°C - 923°C, which makes it suitable for high-temperature applications. It has a thermal conductivity of 55 W/m K and an electrical conductivity of 8.5% IACS, which makes it a good electrical conductor.
Mechanical Properties
One of the significant advantages of the C90300 Tin Bronze is its outstanding mechanical properties. It has a high tensile strength of 600 MPa, a yield strength of 300 MPa, and an elongation of 10%. Its hardness is 150 Brinell, which makes it highly wear-resistant and suitable for heavy-duty applications.
