China is a global producer and consumer of alumina. Aluminum is widely used in many fields. Alumina is the main raw material for aluminum production. With the development of the economy and the continuous optimization of China’s industrial structure, China’s alumina production capacity continues to increase. According to the "China Alumina Industry Demand and Investment Analysis Report" released by the Prospective Industry Research Institute, the cumulative output of my country’s alumina from January to December 2016 reached 60.83 million tons, a year-on-year increase of 7.94%. For the majority of enterprises and capital . The development of alumina industry is also a good opportunity.

　　Alumina plates are mainly based on 5 series, among which 5005 aluminum plates, 5052 aluminum plates, 5083 aluminum plates, 5086 aluminum plates, 5182 aluminum plates and 5251 aluminum plates are more common. Alumina plates are mainly used in rail transit, automobile vehicles, ship transportation, electronics and construction And engineering molds and other fields.

　　Xintai Aluminum, as an excellent enterprise among the manufacturers of aluminum plates, strips and foils in China, has a rigorous work process, sophisticated equipment and rich experience, and the alumina plates produced have their own performance advantages.

　　1. High hardness, good corrosion resistance

　　In the anodic oxidation experiment, the aluminum plate is placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode, and electrolysis is carried out under specific conditions and an external current. The aluminum plate of the anode is oxidized to form a thin layer of aluminum oxide on the surface, the thickness of which is 5-20μm, and the hard anodized film can reach 60-200μm. The product has the characteristics of high hardness, good insulation, strong corrosion resistance and strong adsorption capacity.

　　2, anti-pollution, fireproof, high safety

　　There are no fingerprints on the surface of the product, no stains, easy to clean, and no corrosion spots. There is no paint and any chemical substances on the surface, it does not burn at 600 degrees, and does not produce toxic gas, which meets the national fire protection and environmental protection requirements.

　　3, good weather resistance, suitable for processing

　　standard thickness oxide film (3μm) anodized aluminum plate does not change color for long-term indoor use, does not corrode, does not oxidize, and does not rust. The anodized aluminum plate with a thick oxide film (10μm) can be used outdoors, and it can be exposed to sunlight for a long time without changing its color. The product can be subjected to continuous high-speed stamping, which is convenient to be directly processed into products without complicated surface treatment, which greatly shortens the product production cycle and reduces the product production cost.

　　However, with the development of my country’s economy and the rapid advancement of various industries such as electronics, machinery, automobiles and other industries, the market’s demand for aluminum is also increasing, and alumina production will continue to grow. The future of the alumina industry is very promising. Optimistic, Xintai will also improve itself and expand the market.
