What is Dura-lumin?

Answer 1

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 wine. 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 passion for the weirdest).

Answer 2

Duralumin is an age-hardened, heat-treatable aluminum alloy that exhibits high strength, good corrosion resistance, and lightweight properties. It is commonly used in aerospace and aircraft manufacturing due to its strength-to-weight ratio. Duralumin was one of the first high-strength aluminum alloys developed and popularized in the early 20th century.

Answer 3

A very strong aluminum alloy.
