Furnace Heating Element Resistance Heating Strip 0cr23al5
General Description
FeCrAl alloy, a high - temperature ferritic iron - chromium - aluminium alloy, endures up to 1350 degrees. Uniquely, 0Cr23Al5 serves as electrical heating elements in high - temp furnaces for heat - treating, ceramics, glass, steel, and electronics.
Feature:
FeCrAl alloys shine with multiple advantages. They have a long service life, heat up rapidly, and offer high thermal efficiency with uniform temperature distribution. These alloys can be used vertically. When operating at the rated voltage, they emit no volatile substances, making them an eco - friendly electric heating wire. They're a cost - effective alternative to expensive nichrome wires and can be customized as per customer needs.
FeCrAl alloys boast outstanding oxidation resistance and remarkable form stability, which contribute to an extended lifespan of the components.
These alloys are commonly utilized as electrical heating elements in industrial furnaces and household appliances.
In contrast to NiCr alloys, Fe - Cr - Al alloys not only feature higher resistivity and a greater service temperature but also come at a more affordable price.
Applications
0Cr23Al5 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.
