Monel 400, K-500
Monel 400 is a large amount, versatile, good performance, high corrosion resistance of nickel-copper alloy. Chemical composition is mainly Cu30% Ni65% and about, plus a small amount of Fe ( 1-2% ) of the composition, also known as MCu-28-1.5-1.8. Organizational structure for the single phase austenite.

The corrosion resistance of Monel capacity generally superior than the nickel and copper, pure nickel is more resistant than reducing the corrosion medium, medium oxidation resistance than the copper corrosion of the sulfuric acid, phosphoric acid, carbon corrosion resistance is very good, in particular, hydrochloric acid corrosion resistance of hot concentrated alkali also have excellent corrosion resistance.
