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
0Cr27Al7Mo2 is an iron-chromium-aluminium alloy (FeCrAl alloy) for use at temperatures up to 1400°C (2552°F). The alloy with the characteristics of high resistivity, low temperature coefficient of
electric resistance, high operating temperature, good oxidation resistance under high temperature. It can equal to kanthal APM .
It is widely used in industrial electric furnace, household electrical appliance and far infrared ray device.
Such as panel heaters, infrared heaters, warming plates, in cartridge heaters, storage heaters, ceramic heaters for cooking plates, kilns elements, radiators, in quartz tube heaters for space heating, toasters, toaster ovens, industrial infrared dryers, coils on molded ceramic fibre for cooking plates with ceramic hobs and so on.
