1Cr13al4 Alkro-thal 14 alloy 750 Bright and Annealed Heating Wire
1Cr13Al4 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.
FeCrAl,a family of iron-chromium-aluminum alloys used in a wide range of resistance and high-temperature applications is also used in the form of resistance wires.
FeCrAl resistance electrothermal alloy has high resistivity, good surface oxidation resistance , and high strength at high temperature, good processing performance and weldability , can be widely used in gold , household appliances , machinery manufacturing industry as heating elements and electrical industry as resistance materials.
