1.Manganin alloy is one kind of electric resistance alloy which is
mainly made of copper,manganese and
nickel.
It has character of small resistance temperature coefficient,low
thermal EMF vs copper E,outstanding long-term stability,good
weldability and workability,which makes it to be superior precision
surveying instrument.such as resistor measure
voltage/current/resistance and more.
It is also high-quality electric heating wire for low-temperature
heating element,such as heater of air-conditioning system,household
heating appliances.

Application of Manganin
Manganin foil and wire is used in the manufacture of resistor,
Particularly ammeter shunt, because of its virtually zero
temperature coefficient of resistance value and long term
stability.
