Wisdom Brand heating alloy alkrothal 720
Introduction
1Cr15Al5 is an iron-chromium- aluminium alloy (FeCrAl alloy) for use at temperatures up to 750°C (1382°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 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.
