Finish

The finish of the surfaces of Alumide items can be easily refined by grinding, polishing or coating. The big advantage of this material is that low wear and non-aggressive finishes can be carried out on the parts through substractive processes such as milling, drilling or lathe turning.

Applications

The Alumide is mainly used for the manufacturing of stiff parts of metallic appearance for applications in the automotive industry, for tool inserts for injecting and printing small production runs or, more simply, for illustrative or exposure models that need a metallic appearance.
