Alloys whose main metal is aluminum are called “Aluminum Alloys”. These are also called light alloys. Aluminum alloys include copper, zinc, silicon, magnesium, manganese, iron, nickel, titanium, etc. It is created by adding elements. Features; They are light, have thermal and electrical conductivity, are suitable for heat treatment and are resistant to some chemical effects. Aluminum alloys are suitable for casting. At the same time, aluminum alloys formed by forging, drawing and rolling are also prepared. Since they are resistant to corrosion and do not pose a danger of poisoning, they are used as a preservative in the pharmaceutical industry and foodstuffs.
