 aluminum vs. steel in brake disc Could someone give me the basics in beginning to analyze this?  I am just now taking thermo and haven't taken structures and properties of materials yet. I know I need to know the conductivity within each of the metals and to the air (same or not the same?).  I need to figure out not just the melting point, but the temperature at which it begins to warp or fail in any way.  I couldn't find any properties other than for room temperature here or elsewhere. I realize the question of a brake rotor has many other complicating effects with the rotation and forces applied by the pad, and probably other things i am too unlearned to realize!  I appreciate any advice as to what to neglect and to take into account. Also, is there a simple answer to quantify the effects of anodizing and heat treating? Thanks so much for any tips. Caroline
