What's the difference of 6063 and 6061 aluminum tube?

- Sep 19, 2018-

Aluminum tubes 6063 and 6061 aluminum tubes are common aluminum tubes. Due to their different aluminum contents, they are also different in corrosion resistance and weldability. Therefore, the application range is also different. It should be determined according to the situation.


6061 has a higher content of Mg, Si and Cr, and the performance is slightly better. The main alloying elements of the 6063 aluminum tube are magnesium and silicon, which are relatively soft compared to 6061. The hardness of 6063 is 8-10WB, the hardness of 6061 is 14-15WB; 6061 is used in various industrial structures requiring high strength, weldability and corrosion resistance. 6063 is used in building profiles, irrigation pipes and vehicles. Extrusion materials for gantry, furniture, fences, etc.


The high-quality aluminum alloy produced by the heat treatment pre-stretching process of 6063 aluminum tube has excellent processing performance, excellent welding characteristics, electroplating property and good corrosion resistance. Widely used in aerospace fixtures, trucks, boats, pipelines, etc
