Description

technical field [0001] The invention relates to the field of alloy technology, in particular to a high-resistance corrosion-resistant electrothermal alloy wire for heating tiles and a preparation method thereof. Background technique [0002] Electrothermal alloy materials are resistance alloys that use the resistance properties of substances to manufacture heating elements. At present, there are two main types of electrothermal alloys: one is iron-chromium-aluminum alloy with ferrite structure; the other is nickel-chromium alloy with austenite structure. These two types of alloys have different properties due to their different structures. However, as electrothermal materials, they all have more advantages, and are widely used in the fields of machinery, metallurgy, electronics, and chemical industry, and occupy an important position in the national economy. The resistivity, corrosion resistance and service life of existing nickel-chromium electrothermal alloy wires for he...
