CuNi44 Resistance wire used for variable and strain resisitance elements in alternative instruments.
Copper nickel alloy constantan wire, which has low electric resisitance, 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.
It has a low temperature coefficient of resistance (TCR), and a wide operating temperature range (below 500°C). It has good properities on mechanical working, high resistance of corrosion. It is used for variable and strain resistance of corrosion. It is used for variable and strain resisitance elements in alternative instruments.
The more composition of Nickel,the more silver white the surface to be.
Applications:
It could be used to make electric heating element in low-voltage apparatus, such as thermal overload relay, low-voltage circuit breaker, and so on.
It could be used to make electric heating element in low-voltage apparatus, such as thermal overload relay, low-voltage circuit breaker, and so on.
