Mainly made using copper, manganese and nickel components, the manganin type heat resistant wire offers all the properties required for precision resistance material. For instance, it provides low temperature coefficient of resistance, low thermal EMF against copper, and great long-term stability of resistance. Today, the alloy wire is widely used in making resistance elements and shunt resistors for precision instruments.

In order to suit customers' various needs, we supply many types of manganin type heat resistant wire, such as 6J13, 6J8, and 6J12.
