A method for hot galvanization (hot-dip galvanizing) of an iron or steel component, the method comprising the following method steps in the order listed below: (a) degreasing treatment of the iron or steel component, in particular in at least one degreasing bath; then (b) optionally rinsing the iron or steel component degreased in method step (a); then (c) pickling treatment of the iron or steel component degreased in method step (a) and optionally rinsed in method step (b), in particular in at least one pickling bath; then (d) optionally rinsing the iron or steel component pickled in method step (c); then (e) flux treatment of the iron or steel component pickled in method step (c) and optionally rinsed in method step (d) by means of a flux composition in a flux bath, wherein the flux bath comprises a liquid phase containing an alcohol/water mixture, wherein the liquid phase of the flux bath contains the flux composition, wherein the alcohol of the alcohol/water mixture of the flux bath is a water-miscible and/or a water-soluble alcohol and is selected from the group of linear or branched, saturated, aliphatic, primary, secondary, or tertiary monohydric C 1 -C 4 alcohols and mixtures thereof, and wherein the flux composition contains as ingredients (i) zinc chloride (ZnCl 2) in an amount within the range from 50 to 95 wt%, (ii) ammonium chloride (NH 4 Cl) in an amount within the range from 5 to 45 wt%, (iii) at least one alkali and/or alkaline earth salt in an amount within the range of 0.1 to 25 wt% and (iv) at least one aluminium salt and/or at least one silver salt in an amount within the range from 5 • 10 -5 to 2 wt%, wherein all of the above-mentioned quantities are based on the flux composition and are to be selected to result in a total of 100 wt%, and wherein the flux composition is free of lead chloride (PbCl 2) and nickel chloride (NiCl 2); then (f) optionally drying treatment of the iron or steel component subjected to the flux treatment in method step (e); then (g) hot galvanization (hot-dip galvanizing) of the iron or steel component subjected to the flux treatment in method step (e) and optionally dried in method step (f) in a galvanizing bath containing an aluminium-containing zinc melt ("Zn/Al melt"). (a) degreasing treatment of the iron or steel component, in particular in at least one degreasing bath; then (b) optionally rinsing the iron or steel component degreased in method step (a); then (c) pickling treatment of the iron or steel component degreased in method step (a) and optionally rinsed in method step (b), in particular in at least one pickling bath; then (d) optionally rinsing the iron or steel component pickled in method step (c); then (e) flux treatment of the iron or steel component pickled in method step (c) and optionally rinsed in method step (d) by means of a flux composition in a flux bath, wherein the flux bath comprises a liquid phase containing an alcohol/water mixture, wherein the liquid phase of the flux bath contains the flux composition, wherein the alcohol of the alcohol/water mixture of the flux bath is a water-miscible and/or a water-soluble alcohol and is selected from the group of linear or branched, saturated, aliphatic, primary, secondary, or tertiary monohydric C 1 -C 4 alcohols and mixtures thereof, and wherein the flux composition contains as ingredients (i) zinc chloride (ZnCl 2) in an amount within the range from 50 to 95 wt%, (ii) ammonium chloride (NH 4 Cl) in an amount within the range from 5 to 45 wt%, (iii) at least one alkali and/or alkaline earth salt in an amount within the range of 0.1 to 25 wt% and (iv) at least one aluminium salt and/or at least one silver salt in an amount within the range from 5 • 10 -5 to 2 wt%, wherein all of the above-mentioned quantities are based on the flux composition and are to be selected to result in a total of 100 wt%, and wherein the flux composition is free of lead chloride (PbCl 2) and nickel chloride (NiCl 2); then (i) zinc chloride (ZnCl 2) in an amount within the range from 50 to 95 wt%, (ii) ammonium chloride (NH 4 Cl) in an amount within the range from 5 to 45 wt%, (iii) at least one alkali and/or alkaline earth salt in an amount within the range of 0.1 to 25 wt% and (iv) at least one aluminium salt and/or at least one silver salt in an amount within the range from 5 • 10 -5 to 2 wt%, (f) optionally drying treatment of the iron or steel component subjected to the flux treatment in method step (e); then (g) hot galvanization (hot-dip galvanizing) of the iron or steel component subjected to the flux treatment in method step (e) and optionally dried in method step (f) in a galvanizing bath containing an aluminium-containing zinc melt ("Zn/Al melt").
