Manganin МНМЦАЖ 3-12-0.3-0.3

The basis of the manganin alloy is copper, the proportion of which can reach from 81.7 to 85.2%. In addition, the material contains from 11.5 to 13.5% manganese, 2.5-3.5% nickel, up to 0.5% iron and up to 0.4% aluminum. The remaining impurities account for less than 0.4%.

Special properties

Manganin wire, rods, tape, foil and sheets stand out for their superior thermal stability. This ensures extremely small changes in electrical resistance at room temperature, which is especially important in the manufacture of highly accurate measuring instruments.

Has good ductility and good weldability. Depending on the special characteristics of the alloy, it can be welded with or without preheating, with subsequent heat treatment and without heat treatment.

Applications

You can buy bars, sheets, foils or manganin wires to make shunts, electrical resistances, resistors, elements household appliances and high-precision measuring instruments, compensating wires.

Manganin wire can be produced with natural silk or enamel insulation , as well as with combined insulation, from these materials.
