FeCrAl alloy 0Cr27Al7Mo2 CrAl high temperature resistance Alloy Resistance Wire (Working Temperature 1400C )

FeCrAl alloy is high resistancec and electrical heating alloy. Fecral alloy can reach process temperature of 2192 to 2282 F,corresponding to a resistance temperature of 2372F.

In order to improve anti-oxidation ability and increase working life, we usually put addition of rare earths in the alloy, such as La+Ce,Yttrium, Hafnium,Zirconium,etc.

It is normally used in electrical furnace, glass top hobs,quartz tube heaters, resistors,catalytic converter,heating elements etc.

0Cr27Al7Mo2 Nominal Analysis

27.00 Cr, 7.00 Al, 2.00 Mo, Bal. Fe

Max contineous working temperature: 1400 C.

Wire diameter: 0.5~12mm

Melting Temperature: 1520 C

Electrical Resistivity: 1.53 ohm mm2/m

Has been used extensively as heating elements in industrial furnaces and electrical kilns.

Has less hot strength than Tophet alloys but much higher melting point.
