HAl77-2 Corrosion Resistance Aluminum Brass Tube For Sea Water Heat Exchanger
1. Description
HAl77-2, a typical aluminum brass, has high strength, hardness and good plasticity. It can be processed by pressure in cold and hot state. It has good corrosion resistance to seawater and brine, and impact corrosion resistance, but it has the tendency of dezincification and corrosion cracking. It is used for condensing tube and other corrosion resistant parts of ships
Our company's brass tube grades mainly include HAl77-2,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.
