schunkgroup@1x.png

Schunk has developed future-oriented composites made of Aluminum Graphite (ALG) for a variety of applications.

The composites are created through the pressurized infiltration of porous graphite with liquid aluminum.  These metal matrix composites (MMCs) impress with their high thermal conductivity, suitable heat-expansion coefficients and very low densities.  

Thanks to outstanding mechanical workability, components can simply be produced from it according to customer specifications.

Below are some examples of products that have been produced.
