yes and no
Yes, anodized aluminum cookware does cost more than non stick cookware. Since there's less demand for it, the production costs are higher.
Anodized aluminum itself is not magnetic because the anodization process forms a non-ferrous oxide layer on the surface. However, the base aluminum material can be magnetic depending on its alloy composition.
Hard anodized cookware is produced for the purpose of stopping food from sticking while cooking. Anodizing is a chemical process that hardens the surface of the cookware to a point where the pan is no longer porous.
Stainless steel, tin lined copper, non-anodized aluminum, clay, enamel, glass, or plastic are all non-reactive. A reactive pan is one made from a material that reacts chemically with other foods, such as aluminum, copper and cast iron. The materials react with acidic foods, imparting a metallic taste and will sometimes discolor light colored soups and sauces a light green or gray! Anodized aluminum has a hard, corrosion-resistant surface that helps prevent discoloration, so it is ok to use. Also, avoid stirring light-colored sauces and soups with an non-anodized aluminum metal spoon or whisk.
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.
Anodized cookware means aluminum cookware with an aluminum oxide coating. Don't cook alkaline foods in it; this will eat away the coating. Use non-metal tools to prevent scratching the surface. Wash by hand rather than in a dishwasher; most dishwashing detergents are strongly alkaline and will eat the coating away quickly.
made of non-corrosive aluminum
While aluminum can be recycled to be made into new aluminum things, aluminum itself is a non-renewable resource, so the answer is no.
Anodized cookware is another variant of non-stick. It is extremely hard, non-porous and there is no concern of a surface material contaminating food if scratched. You can use metal utensils with it.
A non-reactive broiling pan would be something made of anodized or Teflon-related coating. This helps prevent the reaction with certain foods and flavors.

Yes. You may wear non-anodized or anodized medals at your option. You are not, however, allowed to mix the two types. Some SNCOs swear by "if you wear anodized buttons, you must wear anodized medals" but this is not accurate and is found anywhere in the uniform manual (MCO P1020.34G). It was true of uniforms in decades past when anodizing vs hand-polished brass was an issue, but today there is no conflict. -Sgt T
