From your phone casing to an aircraft's wings - aluminum alloys are everywhere.
They are divided into 8 series, each with its own composition, advantages, and applications.
📊 The 8 Families at a Glance
| Series | Main Alloying Element | Key Advantages | Typical Uses |
|---|---|---|---|
| 1xxx | Pure Aluminum | Excellent conductivity, corrosion resistance | Wires, foil, heat sinks |
| 2xxx | Copper | High strength, aerospace-grade | Aircraft structures, rivets |
| 3xxx | Manganese | Corrosion-resistant, easy forming | Roofing, beverage cans |
| 4xxx | Silicon | Heat & wear resistant | Pistons, welding materials |
| 5xxx | Magnesium | Strong, excellent corrosion resistance | Ships, fuel tanks |
| 6xxx | Mg + Si | All-round performance, heat-treatable | Windows, bicycles |
| 7xxx | Zinc | Ultra-high strength | Landing gear, defense parts |
| 8xxx | Lithium & others | Low weight, high rigidity | Satellites, spacecraft |
