Alumium Thermal Contact Resistance

I am looking for a Thermal Contact Resistance value for 6061-T6 alumium with 63 RMS finish. The predefined value in Flow (2.54 micrometer roughness) is similar to values given in the text "Cooling Techniques for Electronic Equipment" by Dave Steinberg. This text lists interface conductance for 7075-T6 at 65 micro inches rms finish but 6061-T6 is "softer" so I would rather find values specific to this material.

 

What are you folks using?
