Friction during extrusion of Aluminum alloy

  1. Sep 23, 2013 #1
    Can anyone provide information on the quality of extruded parts tolerance from 6061 and 6063 Aluminum alloy. I would like to have very tight tolerance on the dimension and have a choice of these 2 alloys, which one would be a preferred material ?

    Is there any information on the viscosity of the Aluminum alloy under extrusion condition, basically in the re-crystallization temperature (but not melt). I guess the viscosity plays a role in determine how the material fills into the tight corners.
