Mirror Polish Aluminum Material: A. Alloy: 6063, 6061, 6005 B. Temper: T5, T6 C. Length: Not longer than 6.5meter D. Normal Anodizing thickness: >=10 micron E. Normal powder coating thickness: 60-100 micron F. Tensile strength: ≥ 16 mpa G. Yield strength: ≥ 110 mpa H. Extensibility: ≥ 8% I. Hardness (HW): ≥ 8 Surface treatment: To do mirror polishing surface of aluminum profile, it usually use chemical polishing, sometimes together with mechanical polishing. Feature of Mirror Polish Aluminum Chemical polishing is a chemical processing method that uses aluminum to selectively self-dissolve in an acidic or alkaline electrolyte solution to level and polish the surface to reduce its surface roughness and PH. The polishing method has the advantages of simple equipment, no power supply, no limitation on the size of the profile. And it also has high polishing speed and low processing cost.
