What are the advantages of aluminum alloy extrusion 1, machining small: Because aluminum alloys can be extruded into any complex section, so long as the design is reasonable, extruded aluminum alloy can be easily assembled, thus reducing the need machining. Some shapes can be obtained only by extrusion, by other processes can not be achieved. 2, low maintenance: Aluminum is a natural durable metal, and the above-mentioned surface treatment but also enhances its durability. 3, light weight: light alloy extruded aluminum profiles colored aluminum manufacturer Jinan weight, high strength and good quality Jinan Which color aluminum and durable. Aluminum and other competition due to differences in material properties, to achieve the same effect of the weight of aluminum construction is only about half of other metal structures, and other metals are not easy to process. 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: 7 ××× series of aluminum plates 7 ××× series aluminum sheet: representative of 7075. Containing mainly zinc. Also belong to the aviation series, aluminum-magnesium, zinc and copper colored aluminum alloy manufacturer in Shandong, heat treatable alloy, are super-hard alloy aluminum color, good abrasion resistance .7075 eliminate stress, not deformed after processing, warpage. All oversized thick 7075 aluminum all the ultrasonic detection, can guarantee no blisters, impurities .7075 high thermal conductivity, can shorten the molding time and improve efficiency. The main feature is the hardness of aluminum alloy 7075 is high hardness, high strength, commonly used in the manufacture of aircraft. Which is a good quality color aluminum color _ _ Alcoa aluminum rolls provided by the Aluminum Co., Ltd. Jinan rolls. 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.
