NiCr Series
- Nickel-chromium, nickel, ferrochrome alloy wire with electric high temperature oxidation resistance, high strength,
- not soften and a series of advantages. When used in a long time, the same type and the permanent elongation is
- very small, which is more Cr20Ni80 alloy with excellent comprehensive properties, is to produce high-quality
- varieties of choice for electric components.
Features of NiCr :
(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 lifespan
