Tin-phosphor bronze rod production and manufacturing because the vast majority of the application of residual materials, a small amount of residue will accumulate in the charge, tin-phosphor bronze will produce some reflection with the residue, many metal oxides will accumulate in copper water, thereby endangering the quality of the commodity, the vast majority of bronze is found that copper liquid surface will appear a layer of similar copper oil items, And the general factory with wood carbon, or rice bran cover to remove the end, but did not think of the copper slag will be accompanied by the inside of the copper liquid. Cold-worked materials are annealed for 1-2h at 200-260°C to produce an annealing hardening effect, which can further improve the strength, plasticity, elastic limit and elastic modulus of the product, and increase the elastic stability.

The slag with refining agent is too loose, and the slag with the same volume is too heavy before application; The initial slag is the slag sample without refining agent, the copper content is higher, and the slag is more inseparable. And it can be seen from the slag fracture surface that the copper content in the slag after refining is very low. There is a lot of copper oil on the surface of the unrefined copper water and copper liquid, which is very sticky when taken out. The copper content in the slag is more than 80%, and it is not easy to solve. Alloys are mainly used in the paper, chemical and food industries to make metal mesh as well as wear-resistant parts and spring parts. Bright red chemicals are often found on high purity graphite continuous casting molds in unrefined furnaces.

1. Good ductility: the tin-phosphous bronze rod has good ductility and a longer service life. After tens of thousands of plug tests, it can maintain stable biting force continuously.

2. No flash arc: long-term application can also maintain stable working characteristics. It is not easy to cause spark discharge, prevent sexual objects from igniting, and then prevent fire accidents.
