How To Make Alloy Materials And Castings For Electrothermal Elements

Electrothermal alloy performance requirements: 1 under high temperature should have good antioxidant(or dielectric atmosphere corrosion resistance) and sufficient creep resistance. There should be a high resistivity, the resistivity temperature coefficient is as low as possible, and it can withstand a large current. 3 There should be good metallurgical production process performance and manufacturing processing performance.

There are two main types of electrothermal alloys: one is ferrochrome aluminum alloy with ferrite tissue; The other is the nickel Chromium alloy of austenitic tissue. Because of the different structure, the properties of the two alloys are not the same. However, as electric and thermal materials, they each have more advantages, so they are widely produced and widely used in various countries.

Electrothermal alloy is an alloy material used to make electric thermal components. When the current passes through the alloy element, the Shanghai heating tube produces a Joule effect that converts electrical energy into heat energy. Electrothermal alloy products are generally made of fine silk, round wire, flat strip material, and can also be made into pipes and castings under special requirements.

Generally, it has the characteristics of high resistivity, heat resistance fatigue, corrosion resistance and high temperature shape stability. It can effectively convert electrical energy into heat energy.

Electrothermal alloys form a dense oxide film on the surface at high temperatures, and Shanghai heating tubes have good antioxidant properties.
