Manufacturing Process of 6063 Extruded Aluminum Square Tube

Aluminum square tubes are made by extrusion, where 6063 aluminum alloy billets are pressed into square cross-section tubes. During the extrusion process, the aluminum alloy billet is heated to high temperatures and then pushed through a mold to form the desired square profile.

• Material Preparation: 6063 aluminum alloy billets are typically made from aluminum ingots or rods. The billets are cleaned and inspected to ensure there are no impurities or defects.
• Heating: The aluminum alloy billets are heated to 450°C to 500°C to increase their plasticity, allowing them to be easily extruded through the mold.
• Extrusion: The heated aluminum billets are fed into an extrusion machine, where high pressure is applied to push the billet through the mold and form the square aluminum tube. The shape and dimensions of the aluminum tube are carefully controlled during this process.
• Cooling: After extrusion, the aluminum square tubes are cooled naturally or with water cooling to ensure their hardness and stability.
• Cutting and Straightening: After cooling, the aluminum square tubes are cut to the required length and straightened to ensure their linearity.

6063 extruded aluminum square tubes are widely used and highly regarded in the construction and decorative industries due to their excellent formability, surface finish, and corrosion resistance. While their strength may be lower than other aluminum alloys, their lightweight and aesthetic qualities make them perfect for applications where both appearance and durability are important, such as windows, railings, signage, and furniture.
