Our electric furnace wires and resistance bands are strictly produced and tested in accordance with industry standards and international standards, and are widely recognized by customers.

Electrothermal alloys are mainly divided into two categories:

1.Austenitic nickel-chromium alloy. The advantages of nickel-chromium alloy are high high temperature strength, reaching an operating temperature of 1200°C, high emissivity, non-magnetic, good corrosion resistance, good plasticity in cold and hot states, easy repair, and can be designed into various forms of heating elements, such as wires, strips, rods, tubes and various heterogeneous materials.

2. Ferrite-structured iron-chromium alloy. The advantages of iron-chromium alloy are high operating temperature in the atmosphere, reaching 1400℃, low specific gravity, high resistivity, large surface load, and cost advantage.

Under poor environmental conditions, nickel-chromium alloy material performs better than iron-chromium alloy. Its products can be made into vertical winding heating elements, wave-shaped heating elements, and wave-shaped radiation surface heating elements, especially the vertical winding 360° rotation that iron-chromium alloy cannot achieve, and only nickel-chromium alloy can do this.
