  • Process for electrolytic graining of aluminum
    Patent number: 3980539
    Abstract: Aluminum is electrolytically grained in an aqueous electrolyte solution containing both hydrochloric acid and boric acid. The hydrochloric acid and boric acid are employed in concentrations which provide grained aluminum that is substantially free of pits, even when high electrolytic current densities are employed in order to complete the graining in a short period of time. Aluminum grained by this process is especially useful as a support for lithographic printing plates.
