Do you know aluminum sheet applications on Hubble Space Telescope?

Last Updated: 2023-08-06

Today is the Hubble Space Telescope launched 27 years anniversary, it has made outstanding contributions to scientific study of human in the space. What are the aluminum sheet applications in the Hubble Space Telescope?

To a Hubble Space Telescope, the mirror is very important. The telescope mirror polishing plating use the thickness of 75 nm aluminum sheet as reflector. And the lightweight aluminum sheet is used to be the instrument and encirclement of the telescope. The characteristics of aluminum sheet applications in Hubble Space Telescope are reflect ability and lightweight. The aluminum sheet are commonly used in aluminum sheet: The lighting, solar reflector sheet, architectural appearance, indoor decoration, ceiling, metope, furniture, cabinets, elevator, signs, namesheet, bags, automotive interior and exterior decoration, household appliances, Aerospace and military aspects. Today we are going to talk about the aluminum sheet applications on aerospace field. At present, in the worldwide, the total amount of aluminum in the field of aerospace accounts for about 5% of the total aluminum consumption, but, because of the large consumption of aluminum sheet and the high technical content of aluminum aerospace field, thus this field become the hot points of aluminum enterprises. C919 aircraft project use medium thickness  aluminum sheet, prodsucts mainly for 7 series aluminum alloy. Aerospace field requirement for aluminum sheet is not only reflected in the high metallurgical quality, high performance of technical indicators and the characteristics of specifications, complex size, its structure, performance, surface accuracy especially external embodiment of strength, plasticity, corrosion resistance and fatigue resistance is extremely strict requirements. 7005 and 7075 aluminum sheet alloy he highest level of prodsucts in aerospace field 7 series aluminum alloy, heat treatment can be improved. For example, 7075 aluminum sheet, and its high strength(high temperature strength and low temperature strength is superior to the other aluminum alloy), its plasticity is good after solid solution treatment, thus has excellent comprehensive mechanical properties. 7075 aluminum is mainly used in the manufacture of high strength, strong corrosion resistance of high stress plane structure, such as the plane of the upper and lower wing side wall sheet, purlin, etc. Current global aerospace aluminum alloy sheet consumption was estimated at 780000 ton, predicts that by 2020 the global aviation aluminum sheet will be 1 million ton.
