Product Description

Mig CuNi 7030 1.2mm Casting Copper Nickel Alloy Resistance Cuni44 Resistivity Constantan Resist Wire 

Product Description

Copper Nickel (CuNi) alloys are medium to low resistance materials typically used in applications with maximum operating temperatures up to 600°C (1,110°F).

With low temperature coefficients of electrical resistance, resistance, and thus performance, is consistent regardless of
temperature. Copper Nickel alloys mechanically boast good ductility, are easily soldered and welded, as well as have outstanding corrosion resistance. These alloys are typically used in high current applications requiring a high level of precision.

 

Feature of NiCr Alloy
(1)High resistance
(2)Low temperature coefficient of resistance
(3)High working temperature
(4)Good corrosion resistance especailly under high temperature
(5)Good performance of anti-carburizing, the atmosphere and surface of sulfur pollution.
(6)Long useful life

Advantages of NiCr alloy
(1)Good corrosion resistance at high temperature.
(2)The price is cheaper than Nickel Chrome wire.
(3) It can be widely used in industrial furnacess, household appliances and far-infrared devices.

The application of NiCr wire
NiCr heating wire is widely used for making electric heating elements in home appliances and industrial furnaces. Typical
applications are flat irons, ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular
elements and cartridge elements.
