First of all, different alloy composition 6061 aluminum sheet sheet and aluminum sheet sheet 6063 is 6 series aluminum sheet, 6 series aluminum sheet is aluminum, magnesium, silicon alloy.7075 aluminum alloy elements for aluminum, zinc. 6061 aluminum sheet and 6063 aluminum difference is small the silicon content of the former between 0.4 to 0.8, magnesium content between 0.8 to 1.2; 0.2 0.6, and 6063 silicon content in magnesium content in 0.45-0.9 because of silicon and magnesium content, general said 6061 than 6063 in hardness. 6061 and 6063 on the tensile strength also has the very big difference, along with the annealing hardening is different under the same conditions the former both tensile strength between less than or equal to 150-290, the latter is less than or equal to between 135-240.
Secondly, different applications
6061 aluminum requires a certain strength, weldability and high resistance to corrosion of all kinds of industrial structural, such as manufacturing truck, tower building, vessel, trolley, and furniture, machinery parts, such as precision machining with tube, rods, shaped material, and sheets.
6063 aluminum sheet sheet is used in building material, irrigation tube, and for vehicle and bench extrusion materials, furniture, fencing, etc.
7075 aluminum sheet sheet is used in the manufacture of aircraft structures and others require high strength, strong corrosion resistance of high stress structure, mold manufacturing.
