SHXT Metal Composite Technology Corporation has a national State Key Laboratory for metal matrix composites.
The company's research team has developed the unique biomimetic composite technology of "micro nano laminated powder metallurgy".
This technology helps scientists find the "strength code" of aluminum alloys – graphene.
Simply put, aluminum is first made into micro nano flake like powder, and then uniformly composite with carbon nanotubes and graphene at the microscopic scale to form "bricks". Then, through process control, a "brick masonry" layered structure of carbon aluminum based composite materials is formed, similar to a wall.
This high-strength lightweight aluminum alloy not only solves the problem of weak stiffness in traditional aluminum alloys, but also has the potential to bring high-end manufacturing fields such as aviation, high-speed rail, and automobiles into the era of lightweight.
In order to transform and apply the laboratory results, SHXT and Shanghai Jiao Tong University formed the Metal Matrix Composite Materials Engineering Center.
At present, SHXT has formed a production line with an annual production capacity of 500 tons, which can prepare ingots weighing up to 0.5 tons per unit, and has developed a series of high modulus graphene reinforced aluminum alloys with medium strength, high strength, and ultra-high strength.
”The low-carbon aluminum alloy has complete intellectual property rights from technical preparation to production equipment, and replacing active aluminum alloy components is expected to reduce weight by 10% -30%, with significant lightweight benefits. Moreover, the technical route, preparation level, and material properties of low-carbon aluminum alloys are at the forefront of the international community.
SHXT has collaborated with application units such as AVIC, China Aerospace Science and Technology Corporation, and CRRC Group to carry out application verification of low-carbon aluminum alloys in aircraft, aerospace carrier structures, "standard multiple unit" trains, new energy vehicles, and other equipment. It is expected to be the first to achieve breakthroughs in new low-carbon aluminum alloy materials.
