    Conductive Graphite Sheets and Bars

    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.

    High-Temperature Graphite Made-to-Order Gaskets

    Image of Product. Front orientation. Made-to-Order Gaskets. High-Temperature Graphite Made-to-Order 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. Gasket cross section and bolt hole diameter must be at least 0.187". 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.
