Химические и механические свойства алюминиевого листа?

Сегодня запущен космический телескоп Хаббл. 27 лет юбилей, он внес выдающийся вклад в научные исследования человека в космосе. Каковы применения алюминиевого листа в космическом телескопе Хаббла??

На космический телескоп Хаббл, зеркало очень важно. Для полировки зеркала телескопа используется толщина 75 алюминиевый лист нм в качестве отражателя. And the lightweight aluminum sheet is used to be the instrument and encirclement of the telescope. Параметры алюминиевой пластины для двери алюминиевый лист applications in Hubble Space Telescope are reflect ability and lightweight. The aluminum sheet are commonly used in aluminum plate: The lighting, solar reflector plate, архитектурный облик, indoor decoration, потолок, metope, мебель, шкафы, лифт, знаки, паспортная табличка, сумки, автомобильная внутренняя и внешняя отделка, бытовая техника, Аэрокосмические и военные аспекты. Today we are going to talk about the aluminum sheet applications on aerospace field. В настоящий момент, in the worldwide, the total amount of aluminum in the field of aerospace accounts for about 5% of the total aluminum consumption, но, 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 алюминиевый сплав серии. 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, представление, surface accuracy especially external embodiment of strength, пластичность, corrosion resistance and fatigue resistance is extremely strict requirements. 7005 а также 7075 aluminum sheet alloy he highest level of products in aerospace field 7 алюминиевый сплав серии, heat treatment can be improved. Например, 7075 алюминиевая пластина, 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, так далее. Current global aerospace aluminum alloy plate consumption was estimated at 780000 тонна, predicts that by 2020 the global aviation aluminum plate will be 1 million ton.
