Separator Manganese copper strip/6J12/6J8 for Electrical Purposes

1.Manganin alloy is one kind of electric resistance alloy which is mainly made of copper,manganese and

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.
