What's the difference between aluminum bronze tin bronze?
1. Contain different elements
Aluminum bronze is a kind of copper base alloy with aluminum as the main alloying element. It is a kind of aluminum bronze containing iron manganese, which belongs to high strength heat-resistant bronze.
Tin bronze with tin as the main alloy element, sometimes added phosphorus, lead, zinc other elements.
2. Different corrosion resistance strength
Aluminum bronze has high strength good wear resistance. It is used for high strength screw, nut, copper sleeve, sealing ring, etc., as well as wear-resistant components. Aluminum bronze can be strengthened by heat treatment, its strength is higher than that of tin bronze
Tin bronze has corrosion resistance wear resistance, good mechanical properties processing properties, can be well welded brazed without spark when it is impacted. Tin bronze has strong corrosion resistance in atmosphere, seawater, fresh water steam. It is widely used in steam boiler ship parts.
Uses of tin bronze aluminum bronze:
Tin bronze is widely used in the electrical electronic industry, accounting for more than half of the total consumption. It is used for all kinds of cables wires, motors transformers, switches printed circuit boards. In the manufacture of machinery transport vehicles, it is used to manufacture industrial valves accessories, instruments, sliding bearings, molds, heat exchangers pumps.
Some domestic brands of aluminum bronze: qal7 is used to manufacture elastic components that need corrosion resistance in the spring case, qal9-4 is used for high strength wear-resistant parts, such as bearings, shaft sleeves, gears, turbines, etc. It can also make nozzle, flange, rocker bracket.
Zhejiang Hongxin Copper Co., Ltd. is an enterprise specialized in the production sales of military copper tubes (rods), precision instrument bourdon tubes, electronic communication capillaries other copper profile products. Through horizontal continuous casting extrusion drawing process, various specifications of tin bronze tubes bars are produced. The grades are qsn8-0.3, qsn7-0.2, qsn6.5-0.4, Qsn6.5-0.1, qsn4-0.3, etc., which are used in instrument industry, communication equipment industry, industrial sewing machine industry, new energy automobile industry, motorcycle industry other industries. The products are produced according to the national standard European Union RoHS organization, SGS test report is provided.
The company was established in Suzhou in 1996 moved to Shanghai in 2003. In 2017, Zhejiang Hongxin Copper Co., Ltd. was established put into production in Lincheng town industrial concentration area of Changxing County. After more than 20 years of development, has become the domestic industry, R & D production of comprehensive strength, a large number of patents, full product specifications of the backbone of the production enterprises, products are widely sold around
