OMG, this must be a new scientific discovery.
Wings, go tell that to several multimillion dollar corporations that they got it wrong and should use aluminum heatsinks and WB's over copper. They should pay you handsomely for this new info you have. I mean you could be rich!!!
Seriously, this has to be a joke but the CAPS and RONG suggest he is very serious.

ALUMINUM IS BETTER, AND WILL RESISTS HEAT AND STAY COOLER BETTER THEN COPPER.

Class is now session.
Aluminum doesn't resist heat at all. It is a thermal condutor but not as good as copper. You are treating them like apples and orange when it's more like valencia orange vs naval orange, copper vs silver, Latoya Jackson vs Michael Jackson.
What you are thinking of is specificity of heat. Cooper's specific heat is 387 J/kg*C and Alum is 900 J/kg*C. The delta Temp is measured by J / (mass * specific heat) = delta T.
Problem is Alum is less dense than copper, so the copper mass is much higher. This makes the delta T of copper and alum about equal. Thermal conductivity is just important and you left that out of the presentation. So go review that topic Wings and know your material before presenting infront of the class.
I give you a D for the presentation and F because of your hacking of the English language.
