Metallic Fibers Main material: Various types of iron chrome aluminum alloy Iron chrome aluminum fiber / metallic fiber Introduce: Iron-chromium alloy is an electrothermal alloy with the following characteristics: (1) High resistivity (2) Small temperature coefficient (3) Long service life (4) high surface load (5) Good oxidation resistance. Iron-Chromium-Aluminum fiber is made from iron-chromium-aluminum wire by a beam stretching process. The diameter ranges from 8 μm to 40 μm. It can be used in higher temperature environments than stainless steel fibers. It is mainly used as a raw material for manufacturing automobile exhaust gas purifiers, high temperature filter felts, burners and the like.
