    Abstract: The method comprises surface treatment of aluminium and aluminium alloys for mechanically high-strength bonding to reactive resin systems, according to which the metal or alloy surface can be first mechanically roughened and degreased. The aluminium or aluminium alloys are subsequently hydrated in water within a temperature range from room temperature to 200 degrees C, followed by tempering at temperatures below the recrystallisation point of aluminium or aluminium alloys.
