4040 Aluminum Profile surface treatment process analysis: Anodic Oxidation vs Spraying vs Electrophoresis
4040 Aluminum Profile Surface Treatment Analysis | AluminumCompo Anodizing: The Ultimate Interpretation of Metallic Colors Technical Principle and Process Anodic oxidation forms a protective aluminum oxide (Al₂O₃) layer through electrolysis. The sulfuric acid anodizing process consists of six core steps: Pre-treatment Alkaline degreasing at 40-60°C removes oil contamination and extrusion lines, followed by nitric acid […]
