Ningbo Huali Steel Co., Ltd. is one of the largest manufacturers of precision 1.4767 FeCrAl alloy coil in China, specializing in the production of 1.4767/Cral6/0Cr21Al6, 1.4725/Cral4/0Cr18Al4, 0Cr15Al5, etc. With our accumulated experience in alloy research and development, we can refine the alloys we use on a continuous basis, and the 0.04mm and 0.05mm FeCrAl for catalytic converters we developed are cost-effectiveness and are favored by manufacturers in related industries around the world.
Precision 1.4767 FeCrAl alloy coil or Cral6 is a ferritic alloy of the FeCrAl family，which can be used as a heating element of resistance up to 1200°C. 0Cr21Al6 must be used in a dry environment in order to avoid rust because this is not a stainless alloy. Elements realized in 0Cr21Al6 have an excellent lifetime in a sulfurous environment，particularly when the atmosphere is also oxidizing. A peroxidation (2 hours at more than 1000°C out in the open air) is necessary when 0Cr21Al6 must operate in a reducing atmosphere. The white-grey aluminum coat formed during the oxidation heat treatment preserves the wire or the ribbon of future chemical attacks. Precision 1.4767 FeCrAl alloy coil is normally used in top cookers with ceramics，pottery furnaces elements，and tubular elements. Because of its resistance to carbonaceous atmospheres，Cral6 is chosen for the production of cigarette lighters and fuel burner elements.
