1. Different alloy elements

6061aluminum plate and 6063 aluminum plate are 6 series aluminum plates. Its main alloy elements are aluminum, magnesium, and silicon. The main alloys of 7075 aluminum sheet are aluminum and zinc.

The silicon content of the 6061 aluminum plate is between 0.4 and 0.8, and the magnesium content is between 0.8-1.2; while the 6063 silicon content is between 0.2-0.6 and the magnesium content is 0.45-0.9.

Due to the content of silicon and magnesium, the 6061aluminum sheet is generally stronger than 6063 in terms of hardness. 6061 aluminum alloy and 6063 aluminum alloy also have a big difference in tensile strength. With different annealing and quenching conditions, the former is between 150-290 or less and the latter is between 135-240 or less.

2. Different applications

6061 aluminum plate is suitable for various industrial structures requiring certain strength, weldability and high corrosion resistance such as trucks ships, precision molding,etc.

6063 alloy aluminum plate is used for building profiles, irrigation pipes and extrusion materials for vehicles, benches, furniture, fences, etc.

7075 aluminum plate is used to manufacture aircraft structures and other high-stress structural parts and molds that require high strength and strong corrosion resistance.
