is an aluminium alloy, with magnesium and silicon as the alloying elements. The standard controlling its composition is maintained by The Aluminum Association. It has generally good mechanical properties and is heat treatable and weldable. It is similar to the British aluminium alloy HE9.
6063 is the most common alloy used for aluminium extrusion. It allows complex shapes to be formed with very smooth surfaces fit for anodizing and so is popular for visible architectural applications such as window frames, door frames, roofs, and sign frames.
Applications requiring higher strength typically use 6061 or 6082 instead.
Since our inception, we are engaged in presenting a wide range of excellent quality Aluminum Flats
. These flats are manufactured at our vendors’ end using quality aluminum and advanced technology. They adhered to industry norms and advanced machines. The offered flats have 0.3mm to 5mm width and thickness. These flats are used in various industries for manufacturing various types of devices and instruments. Furthermore, clients can get the flats from us at a variety of thickness and sizes. Features:
- Temper O, H12, H14, H16, H24
- Thickness 0.3mm to 5mm
- Dimension is 100mm to 1360mm
- Utensils making companies
- Hard engineering machines
- Tools making firms
The alloy composition of 6063 is: 
- Silicon minimum 0.2%, maximum 0.6% by weight
- Iron no minimum, maximum 0.35%
- Copper no minimum, maximum 0.10%
- Manganese no minimum, maximum 0.10%
- Magnesium minimum 0.45%, maximum 0.9%
- Chromium no minimum, maximum 0.10%
- Zinc no minimum, maximum 0.10%
- Titanium no minimum, maximum 0.10%
- Other elements no more than 0.05% each, 0.15% total
T6 temper 6063 has an ultimate tensile strength of at least 190 MPa (28,000 psi) and yield strength of at least 160 MPa (23,000 psi). In thicknesses of 3.15 millimetres (0.124 in) or less, it has elongation of 8% or more; in thicker sections, it has elongation of 10%.
6063 is used for architectural fabrication, window and door frames, pipe and tubing, and aluminium furniture.
6063 is highly weldable, using tungsten inert gas welding. Typically, after welding, the properties near the weld are those of 6063-0, a loss of strength of up to 30%. The material can be re-heat-treated to restore a higher temper for the whole piece.
