Product Details
Superb Heater Technology has been focused on the production of nickel-chromium (nicr) alloys since 1985, which is well-known as one of the leading manufacturers and suppliers of nickel-chromium (nicr) alloys. In the past years, we owned strong reputation for the high quality, reliable performance and strong durability of our products. Should you are interested, please feel free to contact our factory.
Nickel-chromium (NiCr) alloys' chemical composition is nickel,chromium and ferrum, it used at operating temperatures up to 1200 degree. Its chemical composition gives good oxidation resistance especially under conditions of frequent switching or wide temperature fluctuations.They are used for electric resistances of appliances or for application of industrial furnaces. Compare to ferrtic alloy, it has better resistance to oxidation,low embrittlement at high temperature, good plasticity (easier to give them a shape compared with FeCrAl. But the price is very more expensive than FeCrAl alloy.
