Abstract

The present invention provides a pickling method for aluminum substrate
  • which comprises supplementing, in the course of pickling of an aluminum substrate, a pickling agent with a solution (A) and a solution (B)
  • to thereby uphold the formulated components within the above concentration ranges,
  • said pickling agent containing 3000 to 50000 ppm of sulfuric acid, 100 to 5000 ppm of a surfactant, 50 to 3000 ppm of an oxidized metal ion or anion and 100 to 5000 ppm of nitric acid,
  • said solution (A) containing 30 to 500 mass parts of sulfuric acid, 1 to 50 mass parts of a surfactant, 0.5 to 30 mass parts of an oxidized metal ion or anion and 30 to 500 parts of water, and
  • said solution (B) containing 0.5 to 30 mass parts of nitric acid, 0.5 to 30 mass parts of an oxidizing agent and 10 to 300 mass parts of water.
