West Aluminum - West Aluminum Industry Telecom: At 9:43 on June 23, with the launch of the last networking satellite of China's beidou-3 global satellite navigation system, Beidou global satellite navigation system moved from China to the whole world, covering the whole world. Chinalco sinal has undertaken the development and trial production of several varieties and specifications of key aluminum alloy materials and components for beidou-3 navigation satellite and launch vehicle, and the "made by Chinalco sinal" once again shines in space.

Beidou system is a global satellite navigation system independently built and operated by China, which is compatible with other satellite navigation systems in the world. It can provide high-precision and reliable positioning, navigation and time service for all kinds of users in the whole world all day and all day.

Compared with Beidou No. 2, Beidou No. 3 has expanded its service capacity by 10 times. Beidou three one can provide services for one belt, one road along the wider area in communications, power, finance, surveying and mapping, transportation, fishery, agriculture, forestry and other fields. The Beidou characteristics will leap to a new height.

Chinalco Southwest Aluminum provides high-precision aluminum materials for beidou-3, such as bars, skin plates, free forgings, oversized plates, forged rings, aluminum lithium alloys, etc., which are mainly used for satellite telescope system, transfer mechanism, solar panels, transition rings, transfer frames, tanks and other key parts of rockets. These high alloy aluminum products have the characteristics of many varieties and specifications, large component size, complex shape and difficult technology. Chinalco Southwest Aluminum organized a research team to overcome many key technical difficulties in material R & D and production, solved a series of technological problems, and achieved a series of scientific research achievements such as melting and casting, heat processing, heat treatment, etc. the high-quality supply guarantee of 2XXX aluminum alloy sheet is one of the highlights.

2XXX aluminum alloy sheet is widely used in the field of Aeronautics and Astronautics. Because of the high requirements on the surface quality, shape and performance of the product, the complex process flow, the difficult production and the low comprehensive yield of the product, how to ensure the supply of the product has always been a problem. However, the thickness of the ultra-thin quench plate applied to the beidou-3 long march rocket is only 0.3mm, which is very difficult to produce, and poses a severe challenge to the technical process and production operation of Sinai aluminum.

In order to break through this problem, Chinalco Southwest Aluminum established a special research team to take effective measures from the aspects of ingot feeding specification, cold rolling process optimization, air cushion system renovation of air cushion furnace, quenching process optimization and straightening process optimization, to solve the surface quality, plate shape and performance problems that plagued the product, and successfully achieved the smooth output of special sheet metal, which is the third global product of Beidou The successful launch of the system "closing star" provides solid material support.

Over the past 55 years, sinal has successively provided a large number of key materials for national key projects such as "Shenzhou" series spacecraft, "Chang'e" series satellite, "Long March" series carrier rocket, "Tiangong" series target aircraft, transport 20 large transport aircraft, C919 domestic large aircraft, Tianyan, high-speed rail, aircraft carrier, ship, etc. In recent years, Chinalco Southwest Aluminum has conscientiously fulfilled the political task of "the first responsibility of building a strong military, independent and controllable", and has always put the national responsibility first, becoming the leading force in the research, development and production of high-end aluminum alloy materials in the key fields of China's aerospace, National defense and military industry.
