Extrusion

If a part can be extruded, it is always a good idea to have it made that way. Both the tooling cost and unit price are the lowest among all mass production processes. The material A6063 used in extrusion has very good mechanical properties and surface appearance. The thermal conductivity of A6063 is slightly lower than pure aluminum, but much higher than the alloy used in die casting. Secondary machining will increase the overall cost, but unless extensive machining is required, the process is still very cost effective.
