Leading China NiCr Alloy Manufacturer | Factory-Direct Nichrome 2030 Products

Ni30Cr20 resistance alloy is composed of nickel-chromium alloy, which has high resistivity, good oxidation resistance, good stability, ductility and good welding performance. The maximum applicable temperature is up to 1100 degrees, which is longer than iron-chromium-aluminum Service life. The alloy is widely used in storage heaters, convection heaters, heavy-duty varistors and fan heaters, as well as deicing components, electric blankets, car seat cushions, substrate heaters, floor heating and various resistances. Compared with Ni80Cr20 and Ni60Cr15 alloys, low-Ni high-resistance electric heating alloys have lower resistivity and maximum service temperature, higher temperature coefficient of resistance, slightly lower oxidation resistance, good vulcanization resistance, and good cold workability. Ni3OCr20 alloy belongs to the nickel-iron-chromium iron-nickel-based corrosion-resistant alloy. The alloy has the characteristics of corrosion resistance, heat resistance, high strength, etc., and its performance is still stable above 816°C. It is widely used in heat exchangers and cracking furnace tubes in fields such as petroleum, chemical industry, metallurgy, aerospace, etc. Traditionally, most domestic and foreign manufacturers have adopted die casting and electroslag remelting process to produce this alloy.
