On August 15, 2022, Hay Think team SDWQ lightweight aluminum technology and industrial base, a piece of aluminum floating on the water in the shape of a honeycomb caught our attention.
This is high-performance aluminum foam, with a density less than half that of water, and a compressive strength five times that of carbon steel. It is widely used in electronic communications, transportation and other fields.
SDWQ Lightweight Material Technology Corporation has planned five projects, including lightweight structural parts, all-aluminum body assembly, foamed aluminum, aluminum profiles, and pilot test base, to create a "from aluminum water-component research and development to manufacturing-vehicle assembly". Complete industrial chain.
The industrial development of SDWQ lightweight technology and industrial base has achieved two major breakthroughs in technology and performance. In terms of technology, two advanced liquid die forging, extrusion forging and composite joining technologies are adopted, both of which have reached the international leading level.
Among them, the liquid die forging production line can produce accurate workpiece size, with an average weight reduction of more than 50% and performance improvement of more than 20%;
Body material composite connection technology, through high-temperature fusion friction welding and other processes, connects different materials at one time, replacing traditional processes such as drilling, screws, and spot welding, which not only saves costs, but also increases strength.
In terms of performance, 2 series of 8 kinds of high-strength and tough aluminum alloy materials developed by SDWQ have comprehensive properties such as strength, fatigue resistance and corrosion resistance improved by more than 20% compared with traditional alloys; steering knuckles, clutches, etc. produced from this high-performance aluminum alloy material Auto parts have successfully passed the technical assessment of the world's top new energy vehicle companies and have entered the supply chain of more than 20 top OEM car companies.
The lightweight profiles independently developed by the company, the body platform, chassis platform and chassis transmission components manufactured by the company reduce the weight by more than 40%, 30% and 50% respectively compared with traditional products.
