C70600 Copper Nickel "90/10"ASTM B151, MIL C15726F, SAE J461, SAE J463C70600 (C706) & C71500 (C715), Copper nickel offers excellent corrosion resistance, especially in marine salt water environments. The main, wrought copper-nickel alloys chosen for sea water service contain 10 or 30 percent nickel. They also have important additions of iron and manganese which are necessary to maintain good corrosion resistance.Typical Uses for C706 Copper Nickel "90/10":AUTOMOTIVE: Power Steering Tube, Brake Lines
CONSUMER: Screw Lamp bases
INDUSTRIAL: Condenser Plates, Condensers, Weld Torch Tips, Heat Exchanger Tubes, Valve Bodies, Evaporator Tubes, Pressure Vessels, Distiller Tubes, Pump Impellers for Oil Refining, Ferrules, Evaporators
