According to the different metal elements contained in aluminum, aluminum can be divided into 9 series. Today, Zhonglian Aluminum is going to introduce the 7 series of aluminum, one of our newest and best sellers among aluminum products.
Features of 7 series aluminum:
7 series aluminum is mainly made of zinc, but sometimes a small amount of magnesium and copper are added, of which Super hard aluminum are alloys containing zinc, lead, magnesium, and copper that are close to the hardness of steel. The extrusion speed is slower than the 6 series alloy, but with good welding performance. 7 series aluminum alloy is widely used in aerospace, which is also known as aviation aluminum with a high cost. Applications: Aviation (aircraft bearing components, landing gear), rockets, propellers, aerospace.
Furthermore, 7 series aluminum alloy is widely used in some high-end electronic products as well. For example, the famous brand iPhone mobile phone frame, back cover, and Apple computer shell are also made of 7 series aluminum alloy material. Not only the foreign brand but the domestic brand, such as Xiaomi, the newly released Mi 8 has a 7 series aluminum frame.
Among all the 7 series aluminum, the 7005 and 7075 are the highest grades, which can be strengthened by heat treatment.
7005: Extruded aluminum alloy, which is used to manufacture both high strength and high fracture toughness of welded structures, such as transport vehicle trusses, rods, containers; Large heat exchangers, and parts that cannot be fused after welding; What's more, 7075 aluminum alloy can be used to make sports equipment such as tennis rackets and softball bats.
7075: 7075 aluminum alloy is used for the manufacture of aircraft structures and futures, which require high strength, corrosion resistance, and high-stress structural parts, die manufacturing.
Guangdong Zhonglian Aluminum specializes in the production of 7 series aluminum profiles with more than 29 years of factory experience, from raw materials to finished products, one-stop production with high quality and good service to satisfy customer demands, let customers rest assured and worry.
