Lead alloy aluminum oxide film different models of different aluminum alloys of different models, the conductivity after chemical conversion treatment, due to differences in the appearance of the color of the film than the difference between the different oxidation process recipe received other more obvious. High purity aluminum alloy aluminum, film speed is slow; low-alloy aluminum aluminum purity, and vice versa. Therefore, depending on the need to master the different aluminum alloy oxidation. To achieve this 5083 alloy aluminum company, different types of aluminum alloy banding not allowed in the same bunch, and therefore can not be controlled in order to avoid their proper oxidation time. Pros and cons of aluminum alloy components can be distinguished at the base erosion, such as alkali corrosion workpiece surface there are too many gray-black film, or a red film, it must be a high silicon aluminum or copper, for this aluminum chemical conversion film in relation to shorten the time, otherwise the resulting film is bound to be difficult to meet the conductivity requirements. According to different aluminum content of alloying elements can be divided into eight series were 1 *** 2 *** 3 *** 4 *** 5 *** 6 *** *** 7 8 *** 1-8 series aluminum uses introduction: 3 ××× series of aluminum plates 3 ××× series aluminum sheet: representative 3003,3004, 3A21 based. Also known as rust-proof aluminum. Our 3 ××× series aluminum production process is more outstanding. 3 ××× series aluminum manganese from 5083 aluminum alloy as the main ingredient, content between 1.0-1.5%. Is a series of anti-rust function better. Routine use in air conditioning aluminum alloy 5083 Jinan much money, refrigerators, cars and other wet environments, the price is higher than 1 ××× series, is a more commonly used alloy series. 5083 alloy aluminum usage, rolls aluminum, aluminum alloy 5083 by Jinan Heshun Aluminium Limited. Jinan Heshun Aluminum Co. (www.jnhsly.com) Shandong Jinan, aluminum products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Aluminum leadership in cis with the staff warmly welcome all inquiries negotiations to create a better future for aluminum rolls.
