The main alloying elements of 6061 aluminum plate are magnesium and silicon, and form Mg2Si. If it contains a certain amount of manganese and chromium, it can neutralize the bad effects of iron; sometimes a small amount of copper or zinc is added to increase the strength of the alloy without significantly reducing its corrosion resistance; there is a small amount of conductive materials In order to offset the adverse effects of titanium and iron on electrical conductivity; zirconium or titanium can refine the grain and control the recrystallized structure; in order to improve the machinability, lead and bismuth can be added. Mg2Si is solid-dissolved in aluminum, which makes the alloy have artificial age hardening function. The main alloying elements in 6061 aluminum plate are magnesium and silicon, which have medium strength, good corrosion resistance, weldability and good oxidation effect.

Matters needing attention in polishing 6061 aluminum plate

 1. We need to pay attention to the problem of chemical agents. We need to plan for 70% phosphoric acid, and we need to add 3% nitric acid and sulfuric acid internally. After the proportioning is completed, we need to stir continuously, and wait until the complete blending. It might as well be processed.

 2. It is necessary to pay attention to the polishing environment and it should be carried out in a clean environment, otherwise it is easy to cause rust problems after chemical spraying. Only processing in a clean environment can prevent this problem from occurring.

 3. Pay attention to the process of operation, and must follow the requirements for processing. More and more workers, they need to wear protective equipment to avoid affecting their own safety.

4. Inspection after operation. After the 6061 aluminum plate is polished, it needs to be inspected to prevent any missing parts and ensure that each part can be placed after processing.
