Ningbo Huali Steel Co., Ltd is a professional manufacturer of Precision 1.4725 FeCrAl Alloy Coil in China, specializing in producing 1.4725/Cral4/0Cr18Al4, 1.4767/Cral6/0Cr21Al6, 0Cr15Al5, etc. Drawing from experience we have gained of cold rolling and our research and developments, we can refine the alloys we use on a continuous basis. We receives worldwide appreciation from all leading manufacturers of catalytic converters for automotive OEMs, diesel particle filters and in the field of fuelcells and electrolyzers.
Precision 1.4725 FeCrAl Alloy Coil or Cral4 iron-chromium-aluminum alloy is an important electric heating alloy. Because it contains a large amount of Cr and Al, a dense oxide film will form on the alloy surface at high temperature, which prolongs the service life of the alloy material. A higher AL content can also increase the resistivity. High resistivity can effectively convert electrical energy into thermal energy and save electric heating materials. At the same time, the price of iron-chromium-aluminum alloy material is about 30% cheaper than that of nickel alloy electric heating alloy and stainless steel alloy material. Therefore, the excellent high-temperature oxidation resistance (up to 1400℃) and high resistivity (up to 1.6) of iron-chromium-aluminum alloy material and low price provide conditions for its large-scale use. Precision 1.4725 FeCrAl Alloy Coil is prepared into micron-sized metal fibers and their products, which can be widely used in high-temperature gas filtration, burners, gas sealing and other aspects.
