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.​

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.​
