Product Description

Model NO.: 0Cr21Al4, OCr25Al5, 0Cr21Al6Nb, 0Cr27Al7Mo2 Material: Ferrum, Chromium, Aluminium Wire Size: 0.018-10mm Ribbon Size: 0.05*0.2-2.0*6.0mm Surface: Acid White@Bright Smooth Trademark: XL Origin: China Product Type: Wire Carbon Content: Low Carbon Strip Size: 0.5*5-5*250mm Bar Size: Diameter10-30mm Treatment: Hydrogen Annealing Specification: SGS. ISO9001 HS Code: 72230000 Our factory is specialized in producing Fe-Cr-Al electric Resistance Alloy wire and strip, our alloys have gone through extensive life tests and are proved to last longer than other equivalent alloy grades available in the market. These wires are made with high quality raw materials from the melting stage.

Ferro-Chrome alloy: OCr15Al5, , 1Cr13Al4, 0Cr21Al4, 0Cr21Al6, 0Cr25Al5, 0Cr21Al6Nb, 0Cr27Al7Mo2, and etc.

Advantages of FeCrAl compared with NiCr:
A higher resistivity (until 1.44 ohm mm² /m)
A temperature of use higher in the air (1300° C against 1200 ° C for Resistohm 80)
A higher charge rate
A good resistance to sulphurous and carbonaceous atmospheres
A lower density which means: With an equal weight of material a more important number of elements (a cheaper unit price)
