Graphite Stir Rod Stick Crucible Stir Rod Long Carbon Stirring Rod Graphite Crucible Stir Stick for Melting Casting Refining Gold Silver Copper

Specification: Graphite rod is a non-metallic product. As a necessary cutting consumable before welding in the carbon arc gouging cutting process it is made of carbon graphite and appropriate binder and is formed by extrusion baked at 2200 ℃ and rotated. It is made of a layer of copper plated after the section which is resistant to high temperature has good electrical conductivity and is not easy to break. It is suitable for cutting metals into shapes that meet the requirements.

Except for vacuum it can only be used in neutral atmosphere or reducing atmosphere. Its coefficient of thermal expansion is small its thermal conductivity is large its resistivity is (8~13)×10-6 Ω·m its workability is better than that of SiC and MoSi2 rods and its high temperature resistanc
