Factory Direct: Top-grade 0Cr21Al4 Heating Resistance Fecral Alloy for Efficient Heat Generation

FeCrAl alloy is one of the most widely used electrothermal alloys. It has the characteristics of high resistivity, thermal fatigue resistance, corrosion resistance, and shape stability at high temperature. The alloy has high surface load and fast heating rate. It has good oxidation resistance and can form a dense oxide film. Good anti-sulfur and anti-carburization properties. Its higher resistivity helps save material and reduce component footprint. But the shortcomings are also obvious. The processing performance of iron-chromium-aluminum alloy is poor, and the material is easy to become brittle after long-term use at high temperature. However, due to its low cost and easy availability of raw materials, it is still widely used in the electric heating material market. FeCrAl heating wire Application Our products (FeCrAl) high resistance electric heating wire materials are salable and widely used for making heating equipment like industrial furnace, civil heating appliance, various electrical resistors and locomotive braking resistor, infrared equipment, liquefied gas infrared heat-resisting net, different kinds of igniting and radiating electrodes and voltage-regulating resistors for motors and so on in Metallurgical machinery, medical, chemical, ceramics, electronics, electrical appliance, glass and other civil or industrial fields. 0Cr21Al4 Chemical composition%
