I just wanted to post this small mini rant.

I know most people marvel over its properties, and many view it as a "classy" building material. But I'm not most people, and personally, I hate the stuff.


From the very first touch, I find the whole material unsatisfying. For thermal properties, it's high thermal conductivity means that when it's cold, it really feels cold, and it feels really hot when it's hot. It's thermal conductivity also means as a drink container, it's only useful if you plan on opening/consuming the beverage right after it has been removed from the refrigerator. Leave it sit on the counter for a bit first, and you might as well throw it back in the fridge before opening it.

Brushed aluminum feels course and "raw" when you touch it, it's not a very refined feel at all.

Polished aluminum solves this "raw" feel, but the polish never lasts due to oxidization and the softness of the metal means aluminum surfaces are very prone to scratching/scuffing.

Welding aluminum is a pain, the high heat transfer rate causes excessive deformations as well as ruins any tempers the material had once before the joining process.


Machining aluminum is relatively nice as it is quite soft, however, that is only when in the presence of coolant. Without coolant, machined pieces overheat and turn the metal gummy causing it to stick to blades/drills/bits.

As far as weight savings go, it is far lighter per cubic volume then most metals. But this only gets the metal so far. As there are high strength steels with better strength/weight ratios.


I didn't realize I had this much resentment toward the material until earlier today, when I found myself preferring the feel of the rubber/plastic otterbox around my HTC One rather then the chiseled aluminum body.
