Aluminum standard potential is -1.67 V, the chemical nature of lively, easy and the role of oxygen in the air to form a dense layer of a solid oxide film, so in the general atmosphere and clean water, aluminum products processing, aluminum has a good corrosion resistance. But it will produce galvanic corrosion when in contact with steel or other metal materials, can cause corrosion of aluminum products processing factories in wet environments in contact with the concrete, cement mortar, lime and other alkaline material, also have contact with the wood, soil, etc. corrosion. Therefore, the need for appropriate corrosion protection. Aluminum, is a chemical element. Its chemical symbol is Al, its atomic number is 13. Aluminum element content in the earth's crust after oxygen and silicon, ranks third, is the crust the most abundant metallic element. In the aluminum products processing oxidized metal species, second only to iron and steel, the second largest category of metal. To the 19th century, aluminum only emerge as a competitive metal in engineering applications, and prevailed. Three important developments in aviation, construction, automotive industry, require material properties of aluminum and its alloys with unique properties, which greatly benefit the production and application of this new metal aluminum. Aluminum is extensively used. Quality aluminum products processing, gold-precision (certified), Bao'an District, aluminum products processing provided by Huizhou Hing Precision Parts Co., Ltd..
