It's hard because of the chemicals that are inside of it. Though aluminum foil is not so hard it's still made out of aluminum.
Many people "mine" old dumpsites for pure metals and other materials. There is, however, no source of pure aluminum in nature. Aluminum ore (Bauxite) is composed of aluminum oxids and hydroxides
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.
The known reserves of Bauxite (the ore from which aluminum is mined) are expected to last another two hundred years or so if we continue to mine it at current rates.
Bauxite is primarily mined through open-pit or strip mining techniques. After being extracted, the bauxite ore is processed to refine the aluminum oxide compound found within it, which can then be used to produce aluminum through the electrolysis process.
The "n" next to a dimension on a drawing typically indicates that it is a nominal dimension, which means it is the target or reference dimension without any tolerance applied. In the context of a part being aluminum and to be hard anodized, the nominal dimension may be specified to ensure that the part can accommodate the additional thickness created by the hard anodizing process.

In Runescape you cannot mine Aluminium Ore.
Aluminum is primarily mined in countries such as Australia, China, Guinea, and Brazil. These countries have large deposits of bauxite, which is the primary ore used to extract aluminum through a process called the Bayer process.
Nodules are hard to mine because they are found in very deep water
Bauxite is the main ore of Aluminum.
Aluminum is not as hard as some other metals, such as steel or titanium. It is relatively soft and lightweight compared to these metals.
Go to the Mine Shack. Enter the Mine. Go to the other Mine (If it is the new Club Penguin). If you see a hard hat and a Jackhammer, Click the Hard hat. And there you go! You have your hat!
copper cost more to mine then aluminum so aluminum will cost less then copper cable.
Yes Very

You get the hard hat in the Cave Mine (the room on the left of the hidden lake and on the up of the Mine, where you drill for coins). Walk to the hard hat that you see and obtain the item.
It is hard to tell where she purchased the aluminum enclosures that she is using, but you can purchase aluminum enclosures from http://www.rselectronics.com/seo/aluminum_enclosures.aspx This website has lots of different aluminum enclosures to choose from.
