Difference Between 7075, 6063 and 6061 Aluminium Sheet Metal

05/03 2017

Aluminium sheet metal can be divided into different alloy grades according to the different alloying elements, different alloy grades of aluminum sheet metal has a different range of applications.Today we explain to you guys what is the difference between 7075 aluminium sheet metal, 6063 aluminium sheet metal and 6061 aluminium sheet metal?
1. Different alloy composition
6063 aluminium sheet metal and 6061 aluminium sheet metal is belongs to 6 series aluminium sheet metal, 6 series is aluminum, magnesium, silicon alloy, 7075 aluminum alloy elements is Aluminum and zinc.
6061 aluminum and 6063 aluminium sheet metal is more subtle differences, the silicon content of the first one is between 0.4 and 0.8.Magnesium content in 0.8-1.2. But 6063 silicon content in 0.2-0.6, Magnesium content 0.45-0.9. Because of silicon and magnesium content. General said 6061 in terms of hardness is better than 6063. 6061 and 6063 have a great difference in the tensile strength. As the annealing and quenching is different, both in the same condition the former tensile strength is less than or equal to 150-290 and the latter is less than or equal to 135-240.

2. Different product uses
6061 aluminium sheet metal requires a certain strength, higher resistance to the various industrial structure. Such as the manufacture of trucks, tower buildings, ships, electric cars, furniture, machinery parts, precision machining, such as the use of tubes, rods, shaped wood, sheet metal.
6063 aluminium sheet metal for building profiles, and irrigation pipe for vehicle, bench, furniture, fences etc. with the extrusion materials.
7075 aluminium sheet metal used in the manufacture of aircraft structure and other requirements of high strength, high corrosion resistance of high stress structure parts, mold manufacturing.
