- Reasons why 7 series aluminum alloy is difficult to oxidize
- Extreme current is a material protection technique that forms an oxide film on its surface. Also known as surface anodizing. After surface anodizing treatment, aluminum alloy materials or products have significantly improved corrosion resistance, hardness, wear resistance, insulation, heat resistance, etc. The metal material that undergoes anodizing treatment the most is aluminum.

- How to remove acid from blind holes after aluminum alloy oxidation
- The residual acid solution in blind holes during the oxidation process of aluminum alloys is a problem that needs to be solved. Due to the special structure of blind holes, acid solution is prone to residue. If not thoroughly removed, it can absorb moisture and become an acidic solution in humid environments, corroding parts and affecting the service life of blind hole parts
