Description of Alloy

Alloy 6063 provides good combination of extrudability and mechanical properties. Its excellent extrudability allows thin-walled hollow shapes, intricate solids and other shapes that are usually difficult to extrude with satisfactory finish, to be produced more easily. It responds well to polishing, chemical brigthening, anodizing and dyeing.

Characteristics

Welding             

• Alloy 6063 is readily welded by MIG & TIG processes. The recommended filler alloy, particularly when welding exposed surfaces that will be anodized for decorative purposes is 5356. Alloy 4043 maybe used in other cases.

Machining           

• Readily machined in all tempers given.

Forming               

• All tempers maybe formed, the softer tempers accepting more severe forming.

Corrosion            

• Excellent resistance to the atmosphere. Particularly suitable for architectural applications.

Temper Available (Hardness)

Extruded Shaped – T5, T6

Chemical Composition

Alloy 6063 is a heat-treatable aluminium-magnesium-silicon alloy
