Tin bronze is actually a metal material with tin as the main alloying element, and its tin content is generally between 3-14%. This material is mainly used to make elastic components and wear-resistant parts, deformed tin bronze The content of tin does not exceed 8%, and sometimes lead, phosphorus, zinc and other elements are added.
Different from tin bronze, beryllium bronze is a kind of tin-free bronze with beryllium as the main alloy component. It contains 1.7 to 2.5% beryllium metal and a small amount of nickel, chromium, titanium and other elements. After quenching and aging treatment, The strength limit can reach 1250 to 1500Mpa, which is close to the level of medium strength steel. It is well shaped in the quenched state and can be processed into various semi-finished products. Beryllium bronze has high hardness, elastic limit, fatigue limit and wear resistance, as well as good corrosion resistance, thermal conductivity and electrical conductivity. There is no spark when impacted, so it is widely used in elastic components, wear-resistant parts and explosion-proof tools.
Industry insiders said that adding lead to tin bronze can improve the machinability and wear resistance of the material, and adding zinc can improve the performance of casting. This alloy has high mechanical properties, wear reduction and corrosion resistance. , and easy cutting, brazing and welding performance, the shrinkage coefficient is relatively small, no magnetism, can use wire flame spraying and arc spraying to prepare bronze bushings, bushings, diamagnetic components and other coatings, used in industry tin bronze, the tin content is mostly between 3 and 14%, and this material with a tin content of less than 5% is very suitable for cold working. 10% of this material, suitable for casting.
