eloxierte

Eloxierte is the German adjective form of eloxiert, commonly used to describe aluminum that has undergone anodizing, an electrolytic oxidation process that produces a durable oxide layer on the metal surface. The term originates from the German acronym ELOXAL (elektrolytische Oxidation von Aluminium), and in everyday use eloxierte typically refers to anodized aluminum products.

Anodizing involves immersing aluminum in an acid electrolyte bath and applying an electric current, which thickens the natural oxide layer and bonds it to the underlying metal. Layer thickness varies by process: decorative anodizing commonly produces a thin, uniform layer for corrosion resistance and coloration, while hard anodizing yields thicker, wear-resistant coatings for industrial applications. The porous oxide structure can be dyed before sealing, allowing a range of colors that remain stable and abrasion-resistant once sealed.

Properties of eloxierte surfaces include enhanced corrosion resistance, increased surface hardness, electrical insulation, and improved adhesion for paints or adhesives. Typical uses span consumer electronics casings, architectural components, automotive parts, cookware, and industrial parts requiring wear resistance. Although anodizing is most closely associated with aluminum, similar electrolytic treatments exist for other metals; however, the German term eloxierte is generally reserved for aluminum.

Environmental and safety considerations include management of acids and sealing agents used in the process. Anodized aluminum remains recyclable, and routine maintenance is limited to gentle cleaning to preserve the oxide layer.
