Why Aluminum and not Plastic?

That's a great question! First of all, Aluminum is far more durable than plastic. Besides looking and feeling more premium than plastic, aluminum is also better at conducting heat. Plastic on the other hand, gets soft when it warms up. This results in heavier scratches, gouges, and possibly worst of all (for us car people anyway) it warps. Environmentally speaking, Aluminum can withstand longer-term use and makes it perfect to be reused or repurposed (almost infinitely). In fact, about 75% of Aluminum ever made is still in use today! When looking from an environmental standpoint, plastic is much more hazardous than aluminum.
