Conductive Graphite Rods
- Color: Black
- Max. Temperature: 800° F
- Tensile Strength: 5,500 psi
- Electrical Properties: Conductive
- Surface Resistivity: See table
A low surface resistivity makes this graphite a good electrical conductor. Since this graphite won't adhere to metal, it can be used to fabricate furnace parts, crucibles, and ingot molds.
