I'm looking into a computer case one that's steel and one that's aluminum
Aluminum is a better conductor.
metals like brass are no longer compounds yet straight forward combos and shortage a particular crystal shape. the expansion of Al or Cu might matter on the particular type (or cyrstalline shape) of the fabric. that's desperate by making use of the temperature and stress of the steel while it solidified. There are section diagrams or stress temperture graphs that instruct this understanding which you will discover in components science3 books. Brass, even nonetheless, is a misture of tih and copper so this is maximum possibly to escalate the main and to have the backside melting ingredient by using fact there are no longer any chemical bonds betweem the Sn and Cu.
Aluminum is a far better conductor of heat. Aluminum has a one higher order of magnitude then steel. Typical value for steel is about 30W/mK whereas aluminum is more likely around 180W/mK. That's the reason why cars radiators are aluminum, and computer fins are usually aluminum as well because it conducts heat a lot better
