Project Description

6J8

Manganese copper is a resistance alloy with copper, manganese and nickel as its main components. It has high resistivity, small temperature coefficient of resistance, low thermoelectric potential of copper and excellent long-term stability of resistance. It is a kind of superior precise resistance material. It is mainly used to make standard resistors, shunts, precise or ordinary resistors, etc.
