Kanthal A1 Wire strip FeCrAl iron chromium aluminium Resistance Heating wire strip 1400 C
ISO9001:2008,ROHS
GB/T1234-1995

Kanthal A-1 FeCrAl iron chromium aluminium Resistance Heating Wire or strip.

Kanthal A1 is a ferritic iron-chromium-aluminium alloy (FeCrAl alloy) with high resistivity and very good oxidation resistance. It is suitable for use at temperatures up to 1400°C (2550°F). The best atomizer wire available. Typical applications for Kanthal A-1 are electrical heating elements in high-temperature furnaces for heat treatment, ceramics, glass, steel, and electronics industries.

Product forms available are:

Round wire

Ribbon (flat wire)

Shaped wire

Stranded wire

conductive wire-Resistance heating wire and resistance wire-Spray wire-Thermocouple wire

The wire is supplied on spools, in coils, in pail pac or as straightened lengths and available with or without coating.
