HSn70-1 Brass Tube For Corrosive Liquids In High Strength And Corrosion Resistant Condenser

1. Description

HSn70-1 tin brass is a single-phase brass of Cu Zn Sn ternary system containing micro-arsenic. The micro arsenic in the copper tube can inhibit the dezincification corrosion and further improve the corrosion resistance of the alloy copper tube. HSn70-1 copper tube has good mechanical properties and is generally used to make heat exchanger and tube contacting corrosive liquid. Especially, it is widely used in inland thermal power plant to make high-strength and corrosion-resistant condenser tube of heat exchanger. In recent years, it has been proved that adding trace elements such as boron and nickel to HSn70-1 can improve the corrosion resistance of the alloy.

Our company's brass tube grades mainly include HAi77-2,HSn70-1, HSn70-1B, HSn70-1AB, H68A copper tube, fin tube and U-tube. The products are produced in strict accordance with the standard, and the finished products can be tested by the third party according to the customer's requirements. These copper tubes are mainly used in power plants, desalination, petrochemical, mechanical ships and automotive heat exchangers. We have rich production experience, professional technology, excellent equipment, superior quality, reasonable price, high-quality service, so that our products sell well all over the world, well received by customers.
