اليوم تم إطلاق تلسكوب هابل الفضائي 27 الذكرى السنوية, لقد قدمت مساهمات بارزة في الدراسة العلمية للإنسان في الفضاء. ما هي تطبيقات صفائح الألمنيوم في تلسكوب هابل الفضائي؟?

إلى تلسكوب هابل الفضائي, المرآة مهمة جدًا. تستخدم طلاء تلميع مرآة التلسكوب سمكًا 75 صفائح الألمنيوم نانومتر كعاكس. And the lightweight aluminum sheet is used to be the instrument and encirclement of the telescope. The characteristics of ورقة الألمنيوم applications in Hubble Space Telescope are reflect ability and lightweight. The aluminum sheet are commonly used in aluminum plate: The lighting, solar reflector plate, architectural appearance, indoor decoration, ceiling, metope, أثاث, خزائن, elevator, علامات, اللوحة, 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. في الوقت الحالي, 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 plate, products mainly for 7 سبائك الألومنيوم سلسلة. Aerospace field requirement for aluminum plate 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, الليونة, corrosion resistance and fatigue resistance is extremely strict requirements. 7005 و 7075 aluminum sheet alloy he highest level of products in aerospace field 7 سبائك الألومنيوم سلسلة, heat treatment can be improved. على سبيل المثال, 7075 لوحة الألومنيوم, 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 plate, purlin, إلخ. Current global aerospace aluminum alloy plate consumption was estimated at 780000 ton, predicts that by 2020 the global aviation aluminum plate will be 1 million ton.
