Conductive Graphite Sheets and Bars

Color: Black
Max. Temperature: 800° F
Tensile Strength: 5,500 psi

Ultra-Fine-Grain Conductive Graphite Sheets

Color: Black
Max. Temperature: 800° F
Tensile Strength: 6,670 psi
Electrical Properties: Conductive
Surface Resistivity: See table

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.

Made-to-Order High-Temperature Graphite Gaskets

When you need a unique shape or size graphite gasket, we will precision cut one for you using your DXF file. This material, also known as Hochdruck, is graphite with stainless steel layers for added strength in hot environments.

First select a thickness, then select a sheet size that’s large enough to accommodate your gasket. Finally, send us your DXF file. Depending on the size of your gasket, we’ll send you as many same-design gaskets as a sheet will yield, up to 20 gaskets for 12"×12" sheets, and up to 40 gaskets for 24"×24" sheets.
