Graphite rod. Graphite products can be customized.

Graphite rods are often used as electric heating elements in high-temperature vacuum furnaces. The maximum operating temperature can reach 3000°C. They are easily oxidized at high temperatures and can only be used in neutral or reducing atmospheres except in vacuum. Its thermal expansion coefficient is small, its thermal conductivity is large, its resistance coefficient is (8~13)×10-6 Ω·m, its processability is better than SiC and MoSi2 rods, it is resistant to high temperatures, has good resistance to extreme cold and heat, and is cheaper.
