Lork Black Finish Monel 400 Nickel Alloy Round Bar for Frames

MONEL nickel alloy is a solid solution alloy that can be hardened by the process of cold working.

MONEL is a trademark of Special Metals Corporation under which a series of nickel-copper alloys are grouped. Commercially there are many types of MONEL available, such as alloy 400, alloy 401, alloy R-405, Alloy K-500 and Monel 404.

The Monel 400 alloy is also known as super alloy monel. This alloy is available in some standard shapes such as hexagon, round, tube, pipe, plate, strip, sheet and wire.

The proportions of copper and nickel used to make monel are the same as that found in the nickel ore found in Ontario mines. This alloy exhibits good corrosion resistance. This datasheet will look into the chemical composition, properties and applications of MONEL 400 alloy.

The chemical composition of MONEL 400 alloy is given in the following table.

The following table discusses the physical properties of MONEL 400 alloy.

The mechanical properties of MONEL 400 alloy are tabulated below.

Some of the other designations that are used to denote MONEL 400 alloy are as below:
