Manganin is a Copper-Manganese-Nickel Resistance alloy; it combines all the properties required of a precision electrical resistance alloy such as high resistivity, low temperature coefficient of resistance, very low thermal effect against copper and good performance of electrical resistance over long periods of time. 

We mainly manufacture 6J13, 6J8, 6J12 .
