6061 and 6063 belong to the aluminum magnesium alloy (+) silicon aluminum alloy 6 series and aluminum alloy 7075 aluminum alloy components, respectively.

The first type has significant differences in basic composition compared to the latter. The difference between 6061 and 6063 is that the silicon content of the former is between 0.4 and 0.8, and the magnesium content is between 0.8 and 1.2; The silicon content between 0.45-0.9 in 0.2 0.6 and 6063 varies depending on the silicon content and magnesium content. Generally, the hardness of 6061 is above 6063. There is also a significant difference in tensile strength between 6061 and 6063. With different annealing hardening, under the same conditions, the former has a tensile strength less than or equal to 150-290, while the latter is less than or equal to 135-240.

Finally, there are significant differences among the three: 1.6061 aluminum alloy plates require certain strength, weldability, and various industrial structures, such as manufacturing trucks, tower buildings, ships, trolleys, furniture, mechanical parts, such as those used for building materials, irrigation pipelines, as well as pipes, bars, forming materials, and precision machining of 2.6063 aluminum alloy plates. 3.7075 aluminum alloy rods are used for manufacturing aircraft structures and future materials, requiring high strength, high stress structure, strong corrosion resistance, and mold manufacturing.
