ABSTRACT:
The invention relates to organoaluminum electrotyles for the electrolytic deposition of aluminum which are characterized in that they consist of KF . 2 AlEt.sub.3 (A), KF . 2 AlMe.sub.3 (B) and MF . 2 Al(iBu).sub.3 (C), wherein M=sodium or potassium or a mixture of both, in a molar ratio of A:B:C of from 2:1:1 to 7:1:1. The organoaluminum electrolytes are dissolved in from 2 to 4.5 moles, based on the amount of MF employed, of an aromatic hydrocarbon which is liquid at 0.degree. C. The invention further relates to a process for the electrolytic deposition of aluminum on electrically conductive materials by using said electrolytes.
