Brass rod: Tin Tin bronze is the tinned metal alloy with the lowest compression ratio. It is used to produce castings with large shape, outer and airtightness. Tin bronze is in the atmosphere, fresh water, fresh water and steam. Abnormal corrosion resistance, commonly used in steam boilers and sea-going vessels. Phosphorus-containing tin bronze has excellent mechanical properties and can be used as a wear-resistant machine and elastic machine for high-precision working machines. Lead-containing tin bronze is used as a wear-resistant machine and sliding bearing. Zinc-containing tin bronze can be used as a high-airtight casting. [2] Molecular formula: CAS No.: Tin bronze tube copper is a non-ferrous metal that is closely related to human beings. It is used in various fields such as electric, light industry, machine making, building property, national defense property, etc. The cost is second only to aluminum. Tin bronze is the most widely used and used in electrical and electronic property, accounting for more than half of the total cost. Used in a variety of cables and wires, electromechanical and transformers, switches and printed circuit boards in the manufacture of machinery and transportation vehicles for the production of property valves and fittings, gauges, plain bearings, molds, heat exchangers and pumps. It is widely used in chemical property to make vacuums, distillation pots, brewing pots, etc. At the top of the national defense property, it is used to make bullets, shells, and guns. For every 3 million bullets produced, 130-140 tons of copper is needed. In the construction of property, it is used as various pipes, pipe fittings, decorating devices, etc.
