6063 T5 Aluminum Square Pipe Description
6063-T5 aluminum square tube is one of the most widely used extrusion products, making it a natural first choice for many projects. At GNEE, this alloy is especially popular in architectural and decorative applications, which is why 6063 aluminum is often known as architectural aluminum.
As a medium-strength aluminum alloy, 6063-T5 aluminum square tube is commonly applied in railings, window and door frames, curtain walls, roofing systems, balustrades, sign frames, shopfitting structures, irrigation systems, building components, electrical applications, marine uses, piping, recreational equipment, storage tanks, as well as truck frames and trailers.
The 6063-T5 aluminum square tube offers an excellent balance of properties, including moderate strength, outstanding corrosion resistance, good weldability, and excellent workability. It also provides reliable machinability for most fabrication needs.
Within the 6000 series aluminum alloys, 6063 and 6061 are the two most popular extrusion grades. Among them, 6063 ranks first due to its superior surface finish and extrusion performance, while 6061 follows as the second most common choice. Both alloys share magnesium and silicon as their primary alloying elements, but 6063-T5 aluminum square tube is particularly favored where appearance, dimensional stability, and smooth finishes are essential.
