SURFACE TREATMENT METHOD OF ALUMINUM MATERIAL
Disclosed is a method of treating a surface of an aluminum material, the method including: degreasing an aluminum material; etching the degreased aluminum material; performing a first desmutting treatment by immersing the etched aluminum material in a 25-35 wt% nitric acid solution at 25 to 30°C for 60 seconds or more; performing a second desmutting treatment by immersing the first desmutting-treated aluminum material in a 5-15 wt% nitric acid solution at 25 to 30°C for 30 seconds to 60 seconds; anodizing the second desmutting-treated aluminum material; coloring the anodized aluminum material; and sealing the colored aluminum material.
