2020 Latest Design Alloy K70 - Thermal Overload Relay Wire CuNi8 Alloy12 CN012 Low-Voltage Low Temperature Heating – TANKII Detail:

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.

Application of copper nickel alloy wire:
1. heating components
2. current-limiting resistance of thermal overload relay
3. low-voltage circuit breaker
4. low-voltage apparatus
