General Description
FeCrAl alloy is made by a high-temperature, ferritic iron-chromium-aluminium alloy which can be used at temperatures up to 1350degrees. Typical applications for FeCrAl are as electrical heating elements in high-temperature furnaces in the heat treating, ceramics, glass, steel, and electronics industries.
Feature
With long service life.Heating up fast.High thermal efficiency.Temperature uniformity. Can use vertically. When being used in the rated voltage,there is no volatile matter.It is an environmental protection electric heating wire. And an alternative to the costly nichrome wire.Can be customized according to customer requirements
FeCrAl alloys are characterized by excellent oxidation resistance and very good form stability resulting in long element life.
They are typically used in electrical heating elements in industrial furnaces and home appliances.
Fe-Cr-Al alloy with high resistivity and serviceability temperature than that for NiCr alloy and also has lower price.
Applications
Iron-chrome-aluminium electric resistor strip is widely used for making electric heating elements in home appliances and industrial furnaces. Typical applications are flat irons, ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular elements and cartridge elements
Application area
Our products are widely used in heat treatment equipment, auto parts, iron and steel manufacturing,aluminum industry, metallurgical equipment, petrochemical equipment, glass machinery, ceramic machinery,food machinery, pharmaceutical machinery, and power engineering industry.
