Widely used in aviation, aerospace, automobile, machinery and other industries. Especially in automobile industry, in order to reduce fuel consumption and improve energy efficiency, replacing steel and iron castings with Al and Ni alloy castings is a long-term development trend. Among them, the refining technology, modification technology, grain refinement technology and rapid detection technology before furnace are focused on. It can develop high-quality aluminium alloy materials, especially aluminium matrix composites, to meet the performance requirements of different working conditions, strengthen the research of cluster alloy smelting process, continue the development of alloy die casting and squeeze casting process and related technologies, and improve the development and research of ferroalloy smelting equipment and related technologies and processes.
