FeCrAl heating element / heating strip for Industrial Furnace
Product Description:
Our company mainly produces high-temperature heating strip with low
impurities, high purity, good surface oxidation resistance, stable
resistivity, corrosion resistance, good processing performance and
high temperature strength and weldability. The products can be
directly processed into winding, Z-shaped, spiral, etc., and widely
used in metal smelting, mechanical manufacturing, industrial
electric furnaces, small electric furnaces, muffle furnaces,
household appliances, transportation and other industries to
produce heating elements and resistance components. Our product
specifications are complete in advanced technology and guaranteed
quality. Welcome new and old customers to order!
The advantages of high temperature heating strip:
Our product has a long service life and high temperature
resistance, such as the maximum service temperature of HRE
iron-chromium aluminium alloy wire can reach 1400℃in the
atmosphere; the oxidation resistance of the product surface is very
good, the AI2O3 film formed after oxidation has a good high
resistivity and resistance; and the allowable surface load is
large; its specific gravity is smaller than that of nickel-chromium
alloy; its resistivity is also higher and the sulfur resistance is
better; but Its price is obviously lower than that of
nickel-chromium alloy.
