Carbon Graphite Machinable Blanks

Metallized Carbon Corporation offers machinable blank material for companies that need to machine mechanical seal primary rings, radial bearings, thrust bearing, case wear rings, vanes for pumps and other mechanical parts. The blanks are readily machinable with conventional carbide or diamond tools.

Metcar seal grade impregnated blanks are made from fine-grained, high strength, carbon-graphite that is fully impregnated with chemically resistant, thermal setting resin or antimony metal. Mechanical seal rings, bearings, and vanes machined from these blanks are impervious to high-pressure liquids. The material is dimensionally stable so that mechanical seal ring faces can be polished to one Helium light band flatness, and the flatness is retained indefinitely. The material is chemically resistant to almost all liquids except extremely strong, oxidizing acids and alkalis.

Standard cylinders and blocks are available in Metcar resin and antimony impregnated and carbon-graphite.
