Constantan is a type of resistance alloy, which is made up of copper and nickel as the main components. It has a low temperature coefficient of resistance (TCR), and a wide operating temperature range (below 500 ℃ ). It has good properties on mechanical working, high resistance of corrosion. It is used for variable and strain resistance elements in alternative instruments.

Karm alloy have common name Nikrothal L/Evanohm/Alloy 800, Karm alloy is made up of nickel,chrome, Aluminum and Iron as the main components. The resistivity is 2~3 times higher than manganin. It has lower temperature coefficient of resistance（TCR）, lower thermal EMF versus copper, good permanence of resistance for a long period of time and strong anti-oxidation. Its working temperature range is wider than manganin (-60~300℃). It is suitable for making fine precision resistance elements and strain.

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.
