Graphite rod

Product Details

Graphite rod is a non-metallic product, as a necessary cutting consumables before welding in the carbon arc gouging cutting process, it is made of carbon, graphite plus appropriate binder, formed by extrusion, and coated with a layer of copper after baking at 2200 °C, with high temperature resistance, good conductivity, not easy to break, and is suitable for cutting metal into a shape that meets the requirements.

Graphite rod is often used in the electric heating body of high-temperature vacuum furnace, the maximum use temperature can reach 3000 °C, it is easy to oxidize at high temperature, except for vacuum, it can only be used in neutral atmosphere or reducing atmosphere. Its thermal expansion coefficient is small, thermal conductivity is large, resistivity is (8~13)×10-6 Ω·m, the processability is better than that of SiC and MoSi2 rods, high temperature resistance, good cold and heat resistance, and the price is cheaper.
