FECRAL HIGH RESISTANCE WIRES 0CR25AL5 WIRE USED FOR Heating Fans
The heating wire is used in many high temperature applications, including electric furnaces, heating plates and heating fans.
FeCrAl 25/5 is an alloy with 25% chromium and 5% aluminum. It can be used at temperatures up to 1250 °
Uses: toasters and hair dryers, fan heaters, ceramic glass top heaters in ranges, boiling (hot) plates, suspended coil and straight wire elements for radiators, convection heaters, as porcupine elements for hot air guns, radiators,
1. Description
FECRAL Has been used extensively as heating elements in industrial furnaces and electrical kilns.
FECRAL Has less hot strength than Tophet alloys but much higher melting point.
