Conductive Graphite Rods
 |
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.

Ultra-Fine-Grain Conductive Graphite Sheets
 |
This graphite is denser and slightly stronger than standard conductive graphite because it has a smaller grain. 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.
