  1. Introduction of FeCrAl resistance wire     FeCrAl
Iron-chromium-aluminium (FeCrAl) metallic alloy is a high temperature alloy which can be used up to 1400° C and is a popular material choice for industrial furnaces.    2. FeCrAl resistance wire feature

1) Excellent resistance to oxidation under heating condition;
2) High resistance and long lifetime;
3) Low temperature coefficient;
4 )Good performance of anti-carburizing, the atmosphere and surface of sulfur pollution.   3. FeCrAl resistance wire advantage  
Fe-Cr-Al resistance alloy has a good corrosion resistance at high temperature. 
Fe-Cr-Al resistance alloy is much cheaper than Nickel Chrome wire. 
Fe-Cr-Al resistance alloy wires are widely used in industrial furnacess, household appliances and far-infrared devices. 
Fe-Cr-Al resistance alloy surface useing temperature can be 1400 degree, (0Cr21A16Nb, 0Cr27A17Mo2 and so on).    PRODUCT APPLICATION   4. FeCrAl resistance wire application 

FeCrAl alloy wire is typically used in industrial furnaces and home appliances. Examples of applications are elements embedded in ceramics for panel 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, toaster ovens, grills, industrial infrared dryers, coils on molded ceramic fibre for cooking plates with ceramic hobs.   FeCrAl 125: Low-cost heating element used in toasters and other small appliances. Long life performance for element operating temperatures up to 1150°C.   FeCrAl 135: Used as heating elements in hot plates, irons, electric furnaces, etc. Improved hot strength compared to 125 grade. Good for continuous element operating temperatures up to 1200°C. Also used in resistor applications and heavy relay switches.   FeCrAl 145: Used for industrial furnaces, kilns and other high temperature applications. Long-life for continuous operating temperatures up to 1300°C. Less increase in resistance on heating and higher oxidation resistance compared to other grades.   PRODUCT PROCESS     TEST EQUIPMENT       CERTIFICATES     Company Information     FAQ   Q1.Do you attend exhibition every year?   A .Yes   Q2.Is there any discount of the nickel wire?   A.  Yes. Bigger quantity will get a discount.   Q3.Information needed if I want a quotation?   A  Name, Standard, Material Grade(Chemical Composition), Size Quantity, Weight.   Q4. Can we visit your company/factory before place the order?   A. Yes. Welcome anytime   Q5: How does your factory do regarding quality control?   A. Quality is priority. We always attach great importance to quality controlling from beginning to end.   How to contact us?   Send your inquiry details in the below for free sample, click "send" now.
