Conductive Sintered Metal Fiber Fecral Fiber With High Electrical Resistance

Iron-chromium-aluminum (FeCrAl) alloys have long been used as high-temperature heating elements. Currently, wrought FeCrAl alloys are under development as one of the promisingcandidates for accident-tolerant fuel (ATF) cladding materials in light-water reactors (LWRs).These alloys have shown excellent corrosion and oxidation resistance in a high-temperature steam environment, compared with current commercial zirconium alloys [6-8]. Their low radiation-induced-swelling and tolerance of off-normal conditions are also worth noting.Under development efforts for ATF FeCrAl alloys, 10–13 wt.% Cr and 5–6 wt.% Al have been employed for improved surface protection effects at both the service temperature and elevated temperatures in accident-case scenarios. Small amount of alloying elements, such as molybdenum (Mo) and/or niobium (Nb), have also been added to improve the strength and control microstructures of FeCrAl alloys.

【Description】

The Fecral fiber is made of iron-chromium-aluminum alloy wire by a bundle drawing process and has a diameter of from 8 μm to 40 μm. Fecral alloy is a new type of electrothermal alloy with high electrical resistance, low temperature coefficient, long service life, high surface load and good oxidation resistance. It can be used in higher temperature environment than stainless steel fibers.

【Application】

It mainly used as raw materials for the manufacture of automobile exhaust gas purifiers(GPF), high temperature filter felts, burners, etc.
