 Copper Nickel Alloy Heating Resistance Wire and StripÂ
Â
 Chengxin copper nickel alloy heating resistance wire and strip has lower electrical resistance, good mechanical, excellent welding and anti-corrosion properties. 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 Kanthal's type cupronickel .
