Description:

bronze with tin as the main alloy element. Tin content is generally between 3 ~ 14%, mainly used to make elastic components and wear-resistant parts. Wrought tin bronze contains no more than 8% tin, sometimes with phosphorus, lead, zinc, etc. Phosphorus is a good deoxidizer and can improve fluidity and wear resistance. Lead in tin bronze can improve machinability and wear resistance, and zinc can improve casting property. The alloy has high mechanical properties, antiwear and corrosion resistance, easy cutting, good brazing and welding properties, low shrinkage coefficient and no magnetism. Wire flame spraying and arc spraying can be used to prepare bronze bushing, shaft sleeve, magnetic resistance elements and other coatings. Size specifications are 1. 6 mm, 2. 3 mm. With high strength, corrosion resistance and excellent casting properties, it has been widely used in various industrial sectors for a long time.

Features:

light weight, good thermal conductivity, high low temperature strength. Often used in the manufacture of copper tubes for heat transfer equipment (eg condensers, etc). It is also used to assemble low temperature pipeline in oxygen making equipment. Copper pipes with small diameters are often used for conveying pressurized liquids (such as lubricating systems, oil pressure systems, etc.) and for measuring pressure pipes used as instruments.

Role:

phosphor bronze has higher corrosion resistance, wear resistance, no sparks during impact. For medium speed, heavy load bearing, working temperature 250 ℃. It has the characteristics of automatic centering, insensitivity to deflection, high uniform bearing capacity, radial load and self-lubricating without maintenance. Tin phosphor bronze is a kind of alloy copper, which has good electrical conductivity and is not easy to heat up, so it is safe and has strong fatigue resistance at the same time.
