Summary of information:
Today, I will introduce you to the common grades of electric heating wires and their corresponding temperatures, so that customers can choose the heating element that suits their requirements. From the material, they are mainly divided into high-resistance nickel-chromium alloy and iron-chromium-aluminum alloy. The resistivity of both is ρ>1Ω. ·mm2/m. First, the common grade and temperature of electric heating wire? 1. Nickel-chromium alloy wire, (1) Cr20Ni80, 1200 ° C,
