ZQSN6-6-3 bronze tube high wear spot bronze tube bronze casting shrinkage is the smallest non-ferrous alloys, used for consumption complex shape, contour clarity, tightness request is not high, castings, bronze in the atmosphere, water, fresh water and steam is very corrosion resistance, widely used for steam boilers and ship parts. Phosphorus-bronze has good mechanical properties, can be used as high-precision machine tools and wear parts elastic parts. Bronze with tin used as wear parts and bearings. Zinc, tin bronze castings can be used for high air tightness. Molecular formula: CAS: Copper is a very intimate relationship with human non-ferrous metal, is used in electrical, light industry, machinery manufacturing, construction industry, defense industry and other areas of common ground, second only to the aluminum consumption in China's nonferrous metal materials. Bronze in the electrical and electronic industry, the most widely used, the largest amount of the total consumption of more than half. For a variety of cables and wires, motors and transformers such, switches and printed circuit boards in the manufacture of machinery and transport vehicles, used in the manufacture of industrial valves and fittings, instrumentation, sliding bearings, such as mold, heat exchange and pump. In the chemical industry is widely used in the manufacture of vacuum distillation pot, brewing pot.

Copper alloy calculated copper weight (kg) = density × thickness × width × length x1 / 1000000 bronze properties containing 3% to 14% tin bronze, also often participate in phosphorus, zinc, lead elements. Is the first human application alloy, has been using about 4,000 years of history. It is corrosion, wear, has good mechanical properties and process performance, and good welding and brazing, when the shock does not produce sparks. Processing of tin bronze and cast into bronze. Bronze pressure processing for tin content of less than 6% to 7%, casting bronze tin content was 10% to 14%. Common brands are QSn4-3, QSn4.4-2.5, QSn7-O.2, ZQSn10, ZQSn5-2-5, ZQSN6-6-3 so on. Bronze casting shrinkage is the smallest non-ferrous alloys, can be used to consume complex shape, contour clarity, tightness request is not high castings. Bronze in the atmosphere, water, fresh water and steam is very corrosion resistance, widely used for steam boilers and ship parts. Phosphorus-bronze has good mechanical properties, can be used as high-precision machine tools and wear parts elastic parts. Bronze with tin used as wear parts and bearings. Zinc, tin bronze castings can be used for high air tightness. Phosphorus is a good deoxidizer copper alloy, alloy increase mobility and improve the process and the mechanical properties of tin bronze, but to increase the degree of inverse segregation. Tin-bronze phosphorus solubility limit is 0.15%, the formation of too large a + δ + Cu3P ternary eutectic melting point of 628 ℃, easy to produce hot shortness during hot rolling, cold working only. Therefore, the deformation amount of phosphorus bronze should not exceed 0.5%, while thermal processing, phosphorus should be less than 0.25%. Phosphorus bronze is well-known elastic material, at the time of low-temperature annealing process, controlling the grain size prior to cold working and post-processing is necessary. Fine grain processing material strength, elastic modulus and fatigue strength higher than the coarse grain processing material, but lower ductility. Cold material at 200 ~ 260 ℃ 1 ~ 2h after low temperature annealing to produce annealed hardening effect can be further improved strength, ductility, elastic modulus and elastic limit articles, and increase the stability of elasticity. Now included in the Chinese national standard total phosphorous bronze four grades. Tin (Sn) × QSn6.5-0.1 alloy which mainly produce elastic element particularly good conductivity spring contact piece, instruments of wear parts and anti-magnetic components such as; Qsn6.5-0.4 alloy is mainly used in papermaking, chemical and food industries for producing a metal mesh, and also for the manufacture of wear-resistant spring parts; QSn7-0.2 alloy to withstand friction under moderate load and sliding velocity parts, such as bearings, bushings, turbines, etc., can also be manufactured elastic components and other mechanical and electrical parts; QSn4-0.3 alloy used in the production of various pipe pressure gauge, as the sensing element, there is a pressure gauge known bronze
