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: 2 ××× series of aluminum plates 2 ××× series aluminum sheet: representative of 2A16 (LY16), 2A06 (LY6). 2 ××× series aluminum is characterized by high hardness Jinan five checkered stock, of which the copper content of the highest five checkered spot Manufacturers Which is good, probably about 3-5%. 2 ××× series aluminum is aviation aluminum in conventional industrial infrequent application. China produced less 2 ××× series aluminum manufacturers. Quality can not be compared with other countries. Aluminum imports mainly from South Korea and German manufacturers. With the development of China's aerospace industry five checkered, 2 ××× series aluminum production technology will be further improved. According to different aluminum content of alloying elements can be divided into eight series were a five checkered shelf *** Which is cheap, 2 *** 3 *** 4 *** 5 *** 6 ** * .7 8 *** *** 1-8 series aluminum uses introduction: 4 ××× series of aluminum plates 4 ××× series aluminum sheet: representative of 4A01. 4 ××× series aluminum belong to a series of high silicon content. Usually silicon content of 4.5-6.0%. Are used in construction materials, machinery parts, forging materials, welding materials; low melting point, good corrosion resistance Product Description: with heat and wear characteristics. Which five checkered stock manufacturers, five checkered, rolls supplied by Alcoa Aluminum Co., Ltd. Jinan rolls. Jinan Heshun Aluminum Co. (www.jnhsly.com) strong, credible, in Jinan, Shandong aluminum products industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead rolls in aluminum and you hand into the brilliant, for a better future!
