Today marks the 27th anniversary of the launch of the Hubble Space Telescope, which has made outstanding contributions to human scientific research in space. What are the applications of 4x8 aluminum sheet in the Hubble Space Telescope?
aluminum sheet
For the Hubble Space Telescope, mirrors are very important. The mirror-polished coating of the telescope uses an aluminum plate with a thickness of 75 nm as a reflector. Lightweight aluminum sheets are used as the telescope's instrument and housing. The application of aluminum plates in the Hubble Space Telescope is characterized by strong reflectivity and light weight. Aluminum sheets are usually used for aluminum sheets: lighting, solar reflectors, building exteriors, interior decoration, ceilings, walls, furniture, cabinets, elevators, signs, nameplates, luggage, interior and exterior car decoration, home appliances, aerospace and military. Today we will talk about the application of aluminum sheet in the aviation field. At present, the total amount of aluminum in the aerospace field accounts for about 5% of the total aluminum consumption worldwide. However, due to the large consumption of aluminum sheets in the aerospace field and the high technical content of aluminum, this field has become a hot spot for aluminum companies. . The C919 aircraft project uses medium and Thin Aluminum Sheet, and the products are mainly 7 series aluminum alloys. The requirements for aluminum plates in the aerospace field are not only reflected in the characteristics of high metallurgical quality, high performance technical indicators and specifications, and complex dimensions, but also in their structure, performance, surface accuracy, especially strength, plasticity, corrosion resistance and fatigue resistance. The performance is extremely strict requirements. 7005 and 7075 aluminum alloy sheets are the highest level products in the aeros pace field 7 series of aluminum alloys, and the heat treatment process can be improved. For example, 7075 aluminum plate has high strength (high temperature strength and low temperature strength are better than other aluminum alloys), and it has good plasticity after solution treatment, so it has excellent comprehensive mechanical properties. 7075 aluminum is mainly used to manufacture high-strength, high-corrosion-resistant high-stress plane structures, such as the upper and lower wing sidewall panels and purlins of aircraft. At present, the global consumption of aviation aluminum alloy sheets is estimated to be 780,000 tons, and it is estimated that by 2020, the global aviation aluminum sheet will be 1 million tons.
