Alpha Overseas(AOS) is a supplier of Cu-Ni 70 / 30 Flanges, which provides tighter controls on mechanical properties and impurities along with a mandatory impact value. Although developed for seawater corrosion resistance, Cupro-nickel 70 / 30 Flanges was soon recognised that the alloys also had inherent resistance to macrofouling. Copper Nickel 70 / 30 Slip On Flanges is readily fabricated, welded and cold worked without any special material considerations. Cu-Ni 70 / 30 Blind Flanges is a copper-nickel alloy with an alpha phase structure, which can be utilized up to 700 Degree F for ASME code heat exchangers and unfired pressure vessels. Cupro-nickel 70 / 30 Weld Neck Flanges is often used in Pump Impellers, Evaporator Tubes, Heat Exchanger Tubes, Distiller Tubes, Refrigerators, Condenser Plates, Process Equipment, etc. The small iron content gives Copper Nickel 70 / 30 Socket Weld Flanges an extraordinary resistance to general corrosion and stress corrosion cracking, making it very suitable and ideal for the marine or industrial industries.
