China Professional China Black Anodized Aluminum Sheet - Golden Brushed Anodised Aluminum Sheet - Ruiyi Manufacturer and Supplier | Ruiyi

Product Description

Anodized Aluminum is corrosion and abrasion resistant meaning it will not fade, chip, peel, or flake. Anodizing is a process used to increase the thickness of the natural oxide layer on the surface of metal parts. It increases corrosion and wear resistance, and during the process the anodized aluminum surface can be dyed into many different colors.

Anodized aluminum sheet is to place the aluminum sheet in corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode for electrolysis under specific conditions with externally applied current. anodized aluminum sheet suitable for manufacturing engine cylinder or other wear-resistant parts

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.

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 plate 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 plate 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 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.
