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.​

These properties make 6063 aluminum suitable for applications requiring moderate strength and excellent finish.​
