Properties of 70 30 CuNi alloy

70 30 Copper-Nickel Cold Forming and Hot Forming

With good hot and cold working properties, copper nickel alloy responds well to most fabrication processes. Due to properties inherited from Copper, Copper-Nickel alloy is can be easily drawn and spin.

70 30 Copper-Nickel Machining

Copper-nickels can be cut using most conventional cutting processes. Plasma-arc cutting is fast, accurate and economical. Laser and abrasive water jet cutting are also possible The machinability rating of 70 30 copper-nickel alloy is 20%.

70 30 CuNi Welding

Copper Nickel Alloys can be easily joined by soldering, brazing and a variety of welding methods such as gas shielded arc welding, spot welding, coated metal arc welding, butt welding, seam welding, brazing, soldering and oxyacetylene welding processes.

70 30 CuNi Corrosion Resistance

Copper-nickel Alloys have good resistance to chloride pitting and crevice corrosion. They have excellent corrosion resistance against moisture, non-oxidising acids, alkalis and salt solutions, organic acids and to gases such as oxygen, chlorine, hydrogen chloride, hydrogen fluoride, sulphur dioxide and carbon dioxide. It is found that the corrosion rates of CuNi alloys are 0.02-0.002mm/year in sea-water.
