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 1400ºCin 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.
Our also can supply the service of custom made. The client just need to tell us the OD of coil and the stated power rate.
