The handy thing to do is to remember the skin depth at a standard frequency 
(100 kHz is good for TC work), and then remember it scales as the square root..
So.. reading off the chart..
Ti ->1.2mm
Al ->.5 mm
Cu -> .15 mm
showing the usual progression as conductivity gets better, the skin depth 
decreases...

Fe(+C) -> .06 mm
showing that ferrous/magnetic materials have very shallow skin depths...

Double the frequency, skin depth multiplied by .707
Quadruple the frequency, skin depth is halved.

Etc...

By the way, Chris, if you scanned that chart or copied it from somewhere, 
you should credit the source.
