In the early morning of May 10, 2022, the Long March 7 Yao-5 carrier rocket carrying the "Tianzhou-4" cargo spacecraft was successfully launched.
In this launch mission, ZLXN Light Alloy Technology Corporation undertook the research and development of key materials of various types and specifications of aluminum alloys for rockets and spacecraft, and provided a variety of aluminum products such as super-large-sized ultra-thin sheets and 3.5-meter-diameter forged rings.
ZLXN provides supporting aluminum alloy materials for the rocket and spaceship launched this time, involving more than 10 specifications and varieties such as forgings, plates, profiles, and pipes.
Mainly used for spacecraft connection frame, middle frame, end frame, surface structure, and key parts such as the transition ring, transfer frame, storage tank of the launch vehicle, especially as the skin plate of the rocket propellant, as well as the skin of the spacecraft. Oversized plates and structural connection forging rings are exclusively provided by ZLXN.
"These key aluminum alloy materials have the characteristics of high metallurgical quality, high-performance technical indicators, many varieties and specifications, and large component sizes.
According to a person from ZLXN's technology research and development department, for example, the aluminum plate used to make the skin of "Tianzhou-4" is the 2.4-meter ultra-wide aluminum alloy sheet produced by ZLXN, which tightly wraps the spacecraft like wearing "armor", It can withstand the ultra-high temperature generated by friction during high-speed flight in space.
In the process of product development, R&D personnel have effectively solved a series of technological problems, obtained a number of scientific research achievements such as casting, thermal processing, and heat treatment, and overcome many key technical difficulties in material R&D and production.
