Aluminum

Often thought of as a lightweight and useless material, Aluminum has been one of the few main reasons that would generate the earlier industrialization of Yudonia. It would be used through history as weapon parts, vehicles, and even toys. In reality, the material is actually very useful, easy to extract, lightweight, durable, and could be almost considered as stainless.

History

The material itself is thought to have been mined at first by the romans as they conquered the islands on their way eastwards. They generally didn't use the material for war purposes, but mostly for decorations and utensils, as well as some exceptional arrowheads and pikes.
During the Aragonese period the metal was left to a side, and most mines stopped extracting the metal, as it was useless for war purposes and very untrusty for other decoration. Some materia was extracted throughout the years, but long transports and low value made the metal almost worthless for people on mainland Aragon.
The British Empire would later reopen most abandoned mines and start refining the metal into its pure form. During empire times, Aluminum was used for many types of creations, including planes, internal high-stress pieces like those in engines, cheap non-silvery cutlery, water canisters... even bullet casings.
Around the start of the 20th century a lot of new ore beta's were found and the metal gained some popularity. Some gun builders decided to give it a try and most were successful at their lightweight and cheap new guns. With the arrival of machineguns and heavy vehicles by ww2 the metal would be used for things like gun magazines and clips, sights, belts, tank pieces, gear-like mechanism pieces, transport equipment, and many more uses. This is why German Reich high ranks decided the islands would make a perfect ally, or shall we say, puppet, in order for them to have a constant and reliable source of the material, but as it would later be proven, the strategy would end up not being worth it and Sweden would later be the country which they would choose as a mining-puppet.

General Claus von Hoffman came to Yudonia, hoping for a pan-German welcome as happened in Austria some time before. He would later escape to Vichy with his hands empty and a broken leg.

In the late 20th and 21th centuries, tin foil and electronic components have probably been the most common uses for the material, but it can also be seen in thins like plane fuselages, car structures, door handles and batteries.
