The tungsten wire mesh heater has a high melting point and good conductivity

The tungsten wire mesh heater is mainly made of tungsten wire spiral mesh, with tungsten wire wound into a spiral shape, similar to common electric heating wires. This spiral shape increases the surface area of the tungsten wire, which can improve heating efficiency. The spiral wire structure is commonly used in applications requiring concentrated or localized heating, especially in environments where high temperatures are needed; the spiral structure helps to reach the desired temperature more quickly.
