Tungsten coil  heater drawing details : 

 

The melting point of tungsten is as high as 3420 dc, which has excellent high temperature strength and excellent corrosion resistance to molten alkali metals and steam.Its high thermal stability ensures that it can work under high temperatures.

 

Tungsten is the most widely used high-temperature metal material because of its high melting point, high strength and hardness, high temperature performance, low resistivity, small expansion coefficient and small electronic escape work.
