Monel 400

Monel is a group of nickel alloys, primarily composed of nickel and copper, with small amounts of iron, manganese, carbon, and silicon. Monel have a good ability on anti-corrssion, especially can be used in seawater. Also the Monel is easy to be fabricated, it can be hot- and cold-working, machining as well as good welding ability.
OHMALLOY can make the monel 400 wire from dia 0.05mm to 8mm. The rod diameter from 8mm to 200mm.

Monel 400 alloy is a multi-purpose material in many industrial applications:

1. Seamless water pipe in the power factory

2. Sea-water exchanger and evaporator

3. Sulfuric acid and hydrochloric acid environment

4. Crude distillation

5. Sea-water in the use of equipment and propeller shaft

6. Nuclear industry and used in the manufacture of uranium enrichment isotope separation equipment

7. Manufacturing hydrochloric acid equipment used in the production of pump and valve.
