Description

Fe-Cr-Al alloy wires and Resistance Wire Heating Element are made of iron chromium aluminum base alloys containing small amounts of reactive elements such as yttrium and zirconium and produced by smelting, steel rolling, forging, annealing, drawing, surface treatment, resistance control test, etc.

The high aluminum content, in combination with the high chromium content let the scaling temperature can reach to 1425ºC (2600ºF);

Heating wires shaped by means of high speed automatic cooling machine of which the power capacity is controlled by computer, they are available as wire and ribbon.
