Melchior (alloy)

The term melchior sometimes refers not only to the copper-nickel alloys, but also ternary alloys of copper with nickel and zinc ("nickel silver") and even a silvered brass.

Melchior is easily deformable by application of pressure, both in the hot and cold state.

The most valuable property of melchior is its high resistance to corrosion in air, freshwater and seawater.

The alloy of 30% Ni, 0.8% Fe, 1% Mn and 68.2% Cu is used in maritime shipping, in particular for the manufacture of condenser tubes.

Nickel gives melchior, unlike brass and bronze, a silver color, and that property, combined with its high corrosion resistance, made it popular for the manufacture of household utensils in the Soviet Union.
