Product Description
Kanthal APM is an advanced powder-metallurgical, dispersion-strengthened, ferritic iron-chromium-aluminium alloy (FeCrAl alloy) for use at temperatures up to 1425°C (2600°F). The alloy is characterized by exceptionally good form stability and oxidation resistance.

Kanthal APM has low tendency to ageing and low resistance change. It has excellent surface oxide properties, which gives good protection in corrosive atmospheres as well as in atmospheres with high carbon potential, and no scaling.

The unique combination of excellent oxidation properties and formstability contributes to long element service life. The alloy's superior form stability reduces the amount of element support.

Typical applications for Kanthal APM are in high-temperature furnaces for firing of ceramics, heat treatment, in laboratory furnaces, in furnaces for electronic industries and in diffusion furnaces.
