Monel® Alloys

Monel® Alloys

A nickel-cooper range, Monel® alloys exhibits outstanding corrosion resistance in a wide range of
media including seawater, hydrofluoric acid, sulphuric acid and alkaline.

Monel® 400

Monel® 400 is a pure nickel alloy that not only resists corrosion, but also offers the pliability required in extreme conditions. Ductile, easy to weld and resistant to caustic alkalis, Monel® alloy 400 has a proven track record when utilised in power plants, brine heaters, salt production equipment and more.

ALLOY K500

Monel® K500 goes one step further. Also referred to as K- Monel® K500 offers the same level of corrosion resistance as alloy 400, with the added advantage of a titanium and aluminium blend. This sophisticated composition allows this nickel alloy to be heat treated to give higher strength and durability, alongside resistance from sub-zero temperatures right up to 480°C. As a result, K500 is often used in pump and valve components, springs and chains.
