Product Description

Copper nickel alloy,which has low electric resistance,good heat-resistant and corrosion-resistant, easy to be processed and lead welded.It is used to make the key components in the thermal overload relay,low resistance thermal circuit breaker, and the electrical appliances.It is also an important material for electrical heating cable.It's similar as s type cupronickel.

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.
