Extruded Graphite

With a perfectly homogenous structure and fine grain, our extruded graphite materials are easy to machine to precision. We currently offer three specialty extruded graphite grades to perfectly match your requirements.

UMF Grade is an ideal economic material for simple applications.

UMFR Grade is the most popular multi-purpose material with higher density, higher mechanical strength, and less porosity.

UMFR-N Grade is suitable for applications which have strict requirements on the material with a very homogeneous grain structure.
