Short Description:

China brushed anodized aluminum sheet copper color anodising black aluminium plate

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 sheets are one of the toughest and most versatile metal products in the market. Once sheet aluminum is anodized, the surface of the metal becomes even tougher than what it was before.

The oxide layer that forms in the aluminum surface has ceramic properties, one of which is a heightened resistance to wear compared to the aluminum on its own. Anodized aluminum is better than untreated aluminum at resisting nicks and scratches, providing a more durable finish.

Aluminum sheet and aluminum plate are essentially the same; the only true distinction is in their respective thickness. Aluminum sheet is any aluminum sheet metal thicker than foil but thinner than 6mm; it comes in many forms including diamond plate, checkered /Chequered plate, expanded, perforated and painted aluminum sheet. Aluminum plate is any aluminum sheet metal that is thicker than 6mm

RuiYi Aluminum is a major aluminum plate supplier. Our aluminum plate is available in a variety of alloys and various weights and thickness. Popular grades include 6061 plate and 7075 aluminum. Selecting the right grade of aluminum plate depends on its intended use. For example, 1100 is a non-heat treatable grade intended for common industrial uses requiring thermal and electrical conductivity, as well as common household items like cooking utensils. The 5052 plate offers excellent corrosion resistance and weldability while 6061 aluminum plate is one of the strongest and most commonly used heat treatable grades. Additional available grades include 3003, 5083, 5086, 5454, 2024, 7075.
