Tin bronze contains 3% to 14% tin, in addition to phosphorus, zinc, lead and other elements often added. It is the earliest alloy used by mankind, and has been used for about 4000 years. It is corrosion-resistant, wear-resistant has good mechanical properties and process properties, can be well welded and brazed, and does not produce sparks when impacted. It is divided into processed tin bronze and cast tin bronze. Tin bronze used for pressure processing contains less than 6% to 7% tin, and the tin content of cast tin bronze is 10% to 14%. Commonly used grades include QSn4-3, QSn4.4-2.5, QSn7-O.2, ZQSn10, ZQSn5-2-5, ZQSN6-6-3, etc. Tin bronze is a non-ferrous alloy with the smallest casting shrinkage, and can be used to produce castings with complex shapes, clear contours and low airtightness requirements. Tin bronze is very resistant to corrosion in the atmosphere, seawater, fresh water, and steam.
Bronze bushings, also known as copper bushings, are divided into various types, including machine bronze rollers and bronze bearings. It is used in various light, large and heavy machinery, and is an important component part of the machinery. The product has the traditional function of tin bronze bearing, with electrolytic copper as the raw material with a variety of trace metal elements, sintered at high temperature and processed by pneumatic centrifugal casting. High hardness, excellent wear resistance, not easy to produce bite phenomenon, good casting performance and cutting performance, good corrosion resistance in the atmosphere and fresh water. In the lack of lubricant and with water lubricant conditions, good sliding and self-lubricating properties, easy to cut, poor casting performance, good corrosion resistance to dilute sulfuric acid. General-purpose structural parts, ships, instruments and other simple castings, such as sleeves, bushings, shaft tiles, sliding blocks, etc.
Bronze with tin as the main alloy element. The tin content is generally between 3 and 14%, mainly used for making elastic components and wear-resistant parts. The tin content of deformed tin bronze does not exceed 8%, and sometimes phosphorus, lead, zinc, and other elements are added. Phosphorus is a good deoxidizer and also improves fluidity and wear resistance. The addition of lead to tin bronze improves machinability and wear resistance, and the addition of zinc improves casting properties. This alloy has high mechanical properties, wear reduction and corrosion resistance, easy cutting and processing, good brazing and welding performance, small shrinkage coefficient, non-magnetic. Available wire flame spraying and arc spraying preparation of bronze bushings, bushings, anti-magnetic components and other coatings. Size specifications Ф1.6mm, Ф2.3mm. with high strength, corrosion resistance and excellent casting properties, has long been widely used in various industrial sectors
In the absence of lubricants and with water lubricant conditions, sliding and self-lubricating properties, easy cutting, casting performance is poor, good corrosion resistance to dilute sulfuric acid.

A plain bearing is a kind of sliding bearing with a special structure, which is mainly composed of an inner ring with an outer sphere and an outer ring with an inner sphere. It can swing and rotate in any direction. Generally, it can bear a large load and has the characteristics of high load-bearing, impact resistance, wear resistance, self-aligning and good lubrication.Because the outer sphere of the inner ring is usually inlaid with composite materials, the joint bearing can produce self-lubrication in operation. Generally used for low-speed swing motion and low-speed rotation, but also in a certain Angle range of tilt motion, when the supporting shaft and shaft shell hole concentricity is large, it can still work normally. Widely used in low-speed swing motion, tilt motion, and rotary motion, such as nuclear power, aerospace, engineering hydraulic cylinder, forging machine tools, construction machinery, automation equipment, automotive shock absorber, hydraulic machinery, and many other industries and fields, is the core components to determine the host operation performance.
