Breaking through industry bottlenecks! The scientific research team in Xi'an is amazing
Aluminum alloy is the main consumable for lightweight manufacturingBut the profit margin of the aluminum industry is limited byAluminum price, energy consumption, labor costRestrictions on terminal selling pricesHow to reduce the impact of the aluminum industry chainCost to increase profit margin?The reporter learned during the interview that the team of Professor Jiang Bailing, a second level professor and doctoral supervisor at the School of Materials Science and Engineering at Xi'an University of Technology, has effectively solved this problem by exploring and developing self-lubricating extrusion molds. Through the preparation technology of self-lubricating and corrosion-resistant eutectic graphite steel profiles, the material has been "strengthened and healthy" from the bone, solving the bottleneck problem in the aluminum industry chain...
