High quality electric resistance 6J40 copper constantan wire
Copper nickel alloy 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.
The more composition of Nickel,the more silver white the surface to be.
