Heating Wire/Mesh is also called electric heating wire and resistance wire. The electric heating wire is a special resistance wire. When the electric wire is connected to both ends of the heating wire, the current is generated through the resistance of the heating wire and generates heat. Because the current passing through is limited, there will be no short circuit. In recent years, iron-chromium-aluminum alloy and nickel-chromium alloy are mostly used for heating wire, and the maximum temperature of iron-chromium-aluminum alloy has reached 1400 ℃. On the basis of heating wire, electric heating elements such as electric heating rod, electric heating plate and electric heating piece have been developed in recent years, but their essence is still electric heating wire, and their principle cannot be separated from electric heating. The heating wire is applied to some products with high temperature and high heat, such as oven, induction cooker, electric water heater, electronic cigarette, etc.
