Aluminium Alloy 6061 Sheet is one of the most widely used grades of aluminium in industries around the world. Known for its excellent mechanical strength, corrosion resistance, and ease of fabrication, this alloy is a preferred choice in aerospace, automotive, and structural applications. Many Aluminium Alloy 6061 Sheet stockists offer this material in various tempers and finishes to meet diverse industrial needs.
Overview of Aluminium Alloy 6061
Aluminium Alloy 6061 is a precipitation-hardened alloy primarily made up of magnesium and silicon. It was developed to provide a combination of high strength, workability, and corrosion resistance, making it one of the most versatile alloys in the 6000 series.
The alloy can be heat-treated to improve its mechanical properties and is commonly available in T4, T6, and T651 tempers, depending on the level of hardness and strength required.
Chemical Composition
| Element | Percentage (%) |
|---|---|
| Aluminium (Al) | 95.8 – 98.6 |
| Magnesium (Mg) | 0.8 – 1.2 |
| Silicon (Si) | 0.4 – 0.8 |
| Copper (Cu) | 0.15 – 0.4 |
| Chromium (Cr) | 0.04 – 0.35 |
This precise balance of elements gives Aluminium 6061 its unique strength, corrosion resistance, and machinability.
