Circulon - reactive or nonreactive?
Manufacturers found that aluminum can be anodized to make it stronger, slicker, more durable, and non-reactive with foods. This applies to many types of cookware, including Circulon and Calphalon.Calphalon, a maker of anodized aluminum cookware explains it this way:"Hard-anodization is an electro-chemical process that hardens aluminum. (Hard-Anodized aluminum is 30% harder than stainless steel.) During hard-anodization, aluminum is submerged in an acid bath, then subjected to electrical charges. The result is a chemical reaction wherein the surface of the aluminum combines with oxygen to become aluminum oxide. This reaction is also known as oxidation, a process which occurs spontaneously in nature. Hard-anodization is actually controlled, accelerated oxidation.
How long will aluminum last if you continue mining and using it at current rates?

Gold is metal so is aluminum why is gold so expensive and aluminum so cheap?
Gold is much rarer (i.e. there is less of it and what there is is harder to find) than aluminum. There is also demand for gold due to special properties that it has that aluminum doesn't that increases the price. Gold is a much more attractive metal than aluminum. Gold does not corrode, while aluminum almost instantly corrodes on contact with air or water producing a hard transparent insulating coating on its surface.
