What is the 6063 aluminum sheet?
6063 aluminum sheet is a go-to material for projects where a sleek appearance, corrosion resistance, and moderate strength are essential. Often dubbed “architectural aluminum,” it’s a favorite in construction, furniture, and decorative applications.
Chemical Composition
6063 aluminum is primarily composed of aluminum, with magnesium and silicon as the main alloying elements. This composition contributes to its favorable mechanical properties and corrosion resistance.
| Cu | Si | Fe | Mn | Mg | Zn | Cr | Ti | Al | Other Each | Others Total |
| 0.10 (max) | 0.20/0.60 | 0.35 (max) | 0.10 (max) | 0.45/0.90 | 0.10 (max) | 0.10 (max) | 0.10 (max) | Remainder | 0.05 | 0.015 |

Mechanical Properties by Temper
The mechanical properties of 6063 aluminum can vary depending on the temper (heat treatment) applied.
| Temper | Ultimate Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Brinell Hardness |
| O | 89.6 | 48.3 | 21 | 25 |
| T4 | 172 | 89.6 | 17 | 46 |
| T5 | 186 | 145 | 11 | 60 |
| T6 | 241 | 214 | 11 | 73 |
These properties make 6063 aluminum suitable for applications requiring moderate strength and excellent finish.
