Anodized aluminum sheet is a sheet metal product consisting of aluminum sheeting exposed to an electrolytic passivation process that imparts a tough, hard-wearing protective finish on its surface.
The protective layer formed by the anodizing process is actually little more than an enhancement of the natural oxide layer that exists naturally on the surface of the aluminum.
Anodizing is an electrolytic process that vastly increases the thickness and toughness of this aluminum oxide layer
الصبغة السوداء هي إحدى تلك الأصباغ المعدة خصيصًا لتلوين الألومنيوم. يتم امتصاص الصبغة بواسطة الطلاء الأنوديك المسامي. كلما تم امتصاص الصبغة أكثر، كان اللون أعمق وحافظ على لونه لفترة أطول اعتمادًا على لونه
الأنودة السوداء الأنودة السوداء هي عملية يتم من خلالها صبغ سطح المعدن المؤكسد باللون الأسود. قبل مرحلة الختم من الأنودة، يمكن صبغ سطح الأكسيد للمعدن. يتم ذلك عندما يكون المظهر الخارجي للمنتج مهمًا.
أnodized aluminum sheet is ideal for a wide range of construction and architectural applications. Notably, anodized aluminum colors will never chip, peel, or fade in sunlight, making them popular for many commercial, industrial, and consumer applications. Common applications include construction components for building exteriors, vents, window frames, doors, and other structural applications.

The aluminum plate of the anode is oxidized, and a thin layer of aluminum oxide is formed on the surface, the thickness of which is 5-20 microns, and the hard anodized film can reach 60-200 microns.
The anodized aluminum sheet has improved its hardness and abrasion resistance, up to 250-500 kg / mm2, good heat resistance, hard anodized film melting point up to 2320K, excellent insulation, and breakdown voltage 2000V, which has enhanced the anti-corrosion performance. It will not corrode for thousands of hours in ω = 0.03NaCl salt spray. There are a large number of micropores in the thin layer of the oxide film, which can absorb various lubricants, which is suitable for manufacturing engine cylinders or other wear-resistant parts.
Anodized aluminum sheet is widely used in machinery parts, aircraft and automobile parts, precision instruments and radio equipment, building decoration, machine housing, lighting, consumer electronics, crafts, household appliances, interior decoration, signage, furniture, automotive decoration and other industries
Anodized aluminum sheet is created through an electro chemical process which allows the color to penetrate the pores of the aluminum, resulting in an actual change in the color of the metal surface. Anodized aluminum is harder and more resistant to abrasion and corrosion.
