Tin bronze is generally between 3 and 14% tin, and is mainly used to make elastic components and wear parts. The tin content of the deformed tin bronze does not exceed 8%, and elements such as phosphorus, lead, and zinc are sometimes added. Phosphorus is a good deoxidizer and improves flow and wear resistance. Lead in tin bronze improves machinability and wear resistance, and zinc addition improves casting performance. The alloy has high mechanical properties, anti-wear performance and corrosion resistance, easy cutting, good brazing and welding performance, small shrinkage coefficient and no magnetism. Bronze bushings, bushings, diamagnetic components, etc. can be prepared by wire flame spraying and arc spraying. Dimensions are Ф1.6mm and Ф2.3mm.
Tin bronze is the non-ferrous metal alloy with the smallest casting shrinkage. It is used to produce castings with complex shapes, clear outlines and low air tightness. Tin bronze is very resistant to corrosion in the atmosphere, sea water, fresh water and steam. It is widely used in steam boilers. And sea boat parts. Phosphorus-containing tin bronze has good mechanical properties and can be used as a wear-resistant part and elastic part of a high-precision working machine. Lead-containing tin bronze is often used as wear parts and plain bearings. Zinc-containing tin bronze can be used as a high-airtight casting.
Bronze containing 3% to 14% tin, in addition to phosphorus, zinc, lead and other elements. It is the earliest alloy for human application and has a history of about 4,000 years. It is corrosion resistant, wear resistant, has good mechanical properties and process properties, and is well welded and brazed without sparking during impact. Divided into processed tin bronze and cast tin bronze. The tin bronze used for press working has a tin content of less than 6% to 7%, and the tin content of the cast tin bronze is 10% to 14%. Commonly used grades are QSn4-3, QSn4.4-2.5, QSn7-O.2, ZQSn10, ZQSn5-2-5, ZQSN6-6-3 and so on. Tin bronze is the non-ferrous metal alloy with the smallest casting shrinkage and can be used to produce castings with complex shapes, clear outlines and low air tightness requirements. Tin bronze is very resistant to corrosion in the atmosphere, sea water, fresh water and steam, and is widely used in steam boilers and marine parts. Phosphorus-containing tin bronze has good mechanical properties and can be used as a wear-resistant part and elastic part of a high-precision working machine. Lead-containing tin bronze is often used as wear parts and plain bearings. Zinc-containing tin bronze can be used as a high-airtight casting.
