Cu-Ni Copper Nickel Alloy Wire CuNi44Mn / CuNi45 Flat Wire Alloy 294 For Resistor
Cu-Ni Alloy Constantan Ribbon CuNi44 / CuNi44Mn / CuNi45 Flat Wire Alloy 294 for resistor
Copper nickel alloy, 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 TANKII's type cupronickel .
The more composition of Nickel,the more silver white the surface to be.
Copper nickel alloy series:
CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23,CuNi30, CuNi34, CuNi44.
Also named NC003, NC005, NC010, NC012, NC015, NC020, NC025, NC030, NC035, NC040, NC050.
