Product Details
Superb Heater Technology has been focused on the production of eleatric heating alloy since 1985, which is well-known as one of the leading manufacturers and suppliers of eleatric heating alloy. 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.
Iron-chromium-aluminium (FeCrAl) alloyshave approximately the same basis composition: 12 to 28 % of chromium, 4.0 to 7 % of aluminum, balance being iron.Some of alloys contain rare molybdenum, niobium,silicium and so on. The alloy has the characteristics of high resistivity,low temperature coefficient and high temperature resistance. Also it has a good corrosion resistance at high temperature, and the price is much cheaper than Nickel chrome wire.So they are an ideal heating material used in industrial furnaces, household appliances and far-infrared devices.
