Corrosion Resistance Monel 400 CuNi Copper Nickel Wire

Monel400 Copper Nickel Alloy Wire/ Strip Good Corrosion Resistance

Monel400 is copper nickel alloy, a kind of corrosion resistant alloy with the largest dosage, the most extensive use and the

best comprehensive performance.This alloy has excellent corrosion resistance in hydrofluoric acid and

fluorine gas medium and good corrosion resistance to hot concentrated alkali liquor.It is also resistant to

corrosion of neutral solutions, water, sea water, atmosphere and organic compounds.One of the important

characteristics of the alloy is that it generally does not produce stress corrosion cracks and has good

cutting performance.

It has good corrosion resistance. In salty water or seawater has excellent resistance to pitting corrosion, stress corrosion ability. Especially hydrofluoric acid resistance and resistance to the hydrochloric acid. Widely used in the chemical, oil, Marine industry.

It is widely used on many aspects,like valve and pump parts, electronic components, chemical processing equipment, gasoline and freshwater tanks, petroleum processing equipment, propeller shafts, marine fixtures and fasteners,boiler feedwater heaters and other heat exchangers.
