Copper Nickel Alloys

In principle, a cupronickel can contain between 1% and 49% nickel, such that copper remains the main element.

Cupronickels have a very low magnetic permeability <1.01.

There is negligible difference in the composition of Alloy K500 versus Alloy 400, but Alloy K500 is appreciably stronger.

Copper has excellent thermal conductivity, explaining its widespread use in household implements such as pots and pans.

Bronzes are copper-based alloys typically with additions of tin, aluminium and silicon.

There are perhaps 400 or more different copper-based alloys.

Monel is a trademark belonging to Special Metal Inc and applied to a family of nickel – copper alloys.

Nickel is added to copper in order to greatly improve its strength and corrosion resistance.
