We all know that tin phosphor bronze plate can be used as anti-wear parts and plastic parts of precision machining high-tech products, lead content tin phosphor bronze plate is generally used as anti-wear parts and roller bearings, iron element tin phosphor bronze plate can be used for high airtight Sexual iron castings.
The solidification range of the tin phosphor bronze plate is large, and the twinning casting defects are more serious; it is not easy to cause concentrated casting defects during solidification, and the capacity shrinkage is not large; the reverse shrinkage of tin is easy to occur in the casting of the phosphor bronze plate, and when it is more serious White and black spots can be seen on the casting surface, and even tin-rich particles, commonly called tin sweat, can be seen. Improving the forging method and production process specifications can reduce the level of reverse shrinkage; in liquid aluminum alloy profiles, tin is easily converted into hard and brittle ginseng. SnO2, the smelter should have sufficient ammonia removal to prevent the reduction of theoretical mechanical properties of aluminum alloy profiles due to ginseng dirt; the sensitivity to ultra-soft gas is not large, and it can be well welded and brazed; destructive No sparks, no magnetism, low temperature resistance, and very high wear resistance.
Tin phosphor bronze plate is a phosphor bronze plate with tin as an important aluminum alloy element. The tin content is generally in the middle of 3 to 14%, and it is mainly used to make elastic components and anti-wear parts. The tin content of the deformed tin phosphor bronze plate does not exceed 8%, and sometimes elements such as phosphorus, lead, and zinc are added. Phosphorus is an excellent oxygen scavenger and also improves flow and abrasion resistance. Putting lead in the tin phosphor bronze plate can improve the drillability and wear resistance, and adding zinc can improve the forging characteristics. This type of aluminum alloy profile has high structural and physical properties, anti-wear properties and corrosion resistance, easy to cut and manufacture, good brazing and electric welding properties, small shrinkage index value, and no magnetism. Coatings such as phosphor bronze plate couplings, couplings, diamagnetic electronic devices can be prepared by cable spark spraying and arc spraying. Specifications Model specifications are Ф1.6mm, Ф2.3mm. With high tensile strength, corrosion resistance and excellent forging properties, it has been widely used in various industries.
