C83600 is tin bronze, American brand, close to the Japanese national standard ZCuSn5Pb5Zn5, close to the Japanese standard BC6, close to the British standard LG2. It is a copper-based alloy with tin as the main alloy element. It is widely used in shipbuilding, chemical industry, machinery, instrumentation and other industries. It is mainly used to manufacture wear-resistant parts such as bearings and bushings, elastic components such as springs, and elastic components such as corrosion-resistant and anti-magnetic components, with high strength, wear resistance and anti-magnetic properties, Good pressure workability under hot and cold conditions, high flame resistance to electric spark, weldability, fiber welding and good processing performance.

Application of Tin bronze
Tin bronze is a nonferrous metal alloy with the smallest casting shrinkage. It is used to produce castings with complex shape, clear outline and low requirements for air tightness. Tin bronze is very corrosion resistant in the atmosphere, sea water, fresh water and steam, and is widely used in steam boilers and marine ship parts. Phosphorus-containing tin bronze has good mechanical properties and can be used as wear-resistant parts and elastic parts of high-precision working machine. Lead-tin bronze is often used as wear-resistant parts and sliding bearings. Zinc-containing tin bronze can be used as high air-tight casting.
Tin bronze is the most widely used and used in the electrical and electronic industries, accounting for more than half of the total consumption. The switches and printed circuit boards used in various cables and wires, motors and transformers are used in the manufacturing of machinery and transport vehicles, and in the manufacturing of industrial valves and accessories, instruments, sliding bearings, molds, heat exchangers and pumps.
It is widely used in the chemical industry to manufacture vacuum vessels, distillation pots, brewing pots, etc.
It is used to manufacture bullets, shells, gun parts, etc. in the national defense industry. 130-140 tons of copper are needed for every 3 million bullets produced.
In the construction industry, it is used for various pipes, pipe fittings, decorative devices, etc.
