First off, to answer what metals are in it, it is 93.5 percent aluminum, 4.4 percent copper, 1.5 percent magnesium, and 0.6 percent manganese. all around it shouldnt be to ridiculuosly expensive, although its not easy to tell any metals exact price being that it constantly changes. 2nd its properties include a good uts (ultimate tensile strength), its an adequatley lightweight metal thanks to the high aluminum content, and it is an age hardenable metal meaning it gets stronger as it is worked, and its molecular structure actualy decreases over the years, or, in other words it ages like a fine ****. and a high tensile strength allows it to be very useful in big factories, like the papermill my dad use to work at. and it was used on the hindenburg. (metalurgy, i guess some just have a passio
