Manganin contains in its composition copper, Nickel, manganese. Can be alloyed with 2.5 and 3.5 per cent cobalt to Nickel (Co+Ni) of 11.5−13.5% Mn. Copper is the basis of its content — about 85%. Brand manganin Mnmc3−12 is small in thermal EMF in a pair with copper, minimum thermal expansion coefficient and high electrical resistance.
The basic qualities
Thermo-EMF in a pair of copper (0,9−1 µv/°C. manganin Operates at a maximum temperature of up to +300°C. unlike Constantan, manganin sensitive to changes in humidity and are susceptible to corrosion in an atmosphere of ammonia vapors and acids. Manganin has the properties to change over time, its resistance. The reason for this are the mechanical stresses generated during winding of the wire, which subsequently leads to a change in the structure of the alloy and some rearrangement of the molecules.
Brand Mnmag 3−12−0,3−0,3−12, and 3 Kg, are made in the form of a wire in accordance with GOST 492−2006 (Nickel, Nickel-copper, Nickel alloys treated under pressure). The alloy is subjected to heat treatment in a vacuum to stabilize the electrical characteristics. While stabiliziruemost all of the properties and increases the homogeneity of the structure. The maximum operating temperature for stabilized grades of alloy of 60−80°C and stable to +200°C.
Alloy actual instrumentation in the manufacture of sensors, shunts, bridge circuits, exemplary resistances. He also serves as the basis of auxiliary devices a high level of accuracy (resistors) due to the small resistance in the room temperature range. The alloy used in the manufacture of hard magnetic (PMT) and magnetic (PMM) wires, Ø 0,02 — 6 mm and the tape width up to 270 mm and thickness up to 0.08 mm. Are also produced in the winding wire enamel insulation (PMMT and PAVM); and insulated wire insulation made of natural silk (PSTMT and PSDM) and wire with one layer of natural silk and enamel insulation (PASAT and PASAM).
