Product Description

Introduction
0Cr21Al4 is an iron-chromium-aluminium alloy (FeCrAl alloy) for use at temperatures up to 900°C (1652°F). The alloy with the characteristics of high resistivity, low temperature coefficient of electric resistance, high operating temperature, good oxidation resistance under high temperature. It can equal to FCHW2..

It is widely used in industrial electric furnace, household electrical appliance and far infrared ray device.
Such as panel heaters, infrared heaters, warming plates, in cartridge heaters, storage heaters, ceramic heaters for cooking plates, kilns elements, radiators, in quartz tube heaters for space heating, toasters, toaster ovens, industrial infrared dryers, coils on molded ceramic fibre for cooking plates with ceramic hobs and so on.
