Far from being rare, aluminum is in fact the third most common element in the Earth's crust, and it is the most common metallic element on Earth. In a pure form, it is silvery white and extremely lightweight. The element blends readily to make lightweight but very strong alloys, and it conducts both heat and electricity very well. In addition, it is non-magnetic, which can be a highly useful property in some applications. The myriad uses for the metal and its compounds include auto manufacture, construction, paints, packaging, cooking utensils, antacids, antiperspirants, and astringents.

While aluminum itself is not inherently toxic, there are some risky aspects to the element. People who work around high volumes of it can become ill, especially if they inhale the element. Children appear to be susceptible to this element, especially if their kidneys do not function well. It appears that it may also cause neuromuscular and skeletal problems, although the exact danger threshold is unknown. Studies of aluminum products has suggested that they are safe for most consumers, although some people may experience contact dermatitis when they handle products like pots, antiperspirants, and antacids.
