PROBLEM TO BE SOLVED: To provide a method for producing an Al-based material containing 6000 series which has good workability, is low-cost, is easy to treat a waste liquid, and has excellent phosphatability and moldability, and the Al-based material I will provide a. SOLUTION: This is an Al-based material characterized in that carbon fine particles are present on the surface, and a solution in which carbon fine particles are dispersed is applied to the surface of the Al-based material, and then the liquid is volatilized and removed, or It is manufactured by adhering an organic substance to the surface of an Al-based material, and then heating the organic substance to a temperature higher than its decomposition temperature to carbonize the organic substance. |
