Specifications
1. Introduction for Fe-Cr-Al Alloy
Fe-Cr-Al alloy wires are made of iron chromium aluminum base alloys , rest is Ferros. and produced by smelting, steel rolling, forging, annealing, drawing, surface treatment, resistance control
test, etc.
The Thermostability of Fe-Cr-Al alloy grows as the increase of the comporstion of Cr and Al, it has superior anti-oxidization ,anti-sulfur and anti-cementite. it also has series of advantages as
small specific gravity ,high surface load ,high resistivity,high service temperature ,long life-span and low price ,etc. therefore,it is widely used in heating elements .
2. Main Application of Fe-Cr-Al alloy wire
FeCrAl alloy wire is widely used for its low price and good performance in industrial furnaces and home appliances likepanel heaters, infrared heaters, warming plates, irons, ceramic pots, in
cartridge heaters for liquid heating, storage heaters, in ceramic heaters for cooking plates, air guns, hobby kilns, radiators, in quartz tube heaters for space heating, toasters, toasterovens,
grills, industrial infrared dryers.
3. Main model alloy No. of Fe-Cr-Al alloy wire
1Cr13Al4, 0Cr21Al4, 0Cr21Al6, 0Cr23Al5,0Cr25Al5,0Cr21Al6Nb,0Cr27Al7Mo2
4. Heating wire product forms and size range
