Product Description
Copper Alloy Wire
Products:
Constantan-type
Constantan-type:
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 500ºC). It has good properties on mechanical working, high resistance of corrosion. It is used for variable and strain resistance elements in alternative instruments
