Product description | HSn70-1 tin brass is a copper zinc tin containing trace arsenic in the a single phase brass, the Chinese national standard (GB5232 - 85) classification of the column as brass. Trace arsenic can inhibit the corrosion of zinc and further improve the corrosion resistance of the alloy. In recent years, the research has proved that adding trace boron, nickel and other elements to HSn70-1 can improve the corrosion resistance of the alloy. HSn70-1 has the tendency of stress corrosion cracking, and it must be carried out to eliminate stress and low temperature annealing. HSn70-1 is easy to crack, to strictly control the content of impurities. |
| Product performance | HSn70-1 has good mechanical properties, for the production of heat exchanger and contact corrosive liquid. |
| Applicable scope | It is widely used in the production of high strength and corrosion resistance of the heat exchanger tubes. |
