Aluminum has the advantages of lightness and sturdiness, and it is an ideal material for "lightweight automobiles". Experiments by international research institutions show that if the weight of the vehicle is reduced by 10%, the fuel efficiency can be increased by 6% to 8%.Thick aluminum stock-YuanfarAluminum In recent years, the global car ownership has grown at an average annual rate of 4%, and the continuous growth of car ownership has increased environmental pressure. In the whole vehicle, the power system, the chassis system and the body are the three systems with the largest mass, and their total mass reaches 83% of the mass of the whole vehicle. Therefore, the use of aluminum materials to manufacture automobile chassis parts "replacing steel with aluminum" is of great significance for realizing the lightweight of automobiles, achieving the goals of energy saving, emission reduction, power improvement, and safety improvement.

Production process of aluminum

The production process of high-performance aluminum automobile chassis profiles is: batching → smelting → refining → transfer injection → degassing, slag removal and refining → casting → homogenization → machining → quality inspection → delivery.

The production process of high-performance aluminum automobile chassis profiles, by optimizing the alloy composition of 6061, formulating reasonable melting, casting, extrusion and heat treatment processes, on the 70MN extruder Ф420mm × 1200mm extrusion barrel, using a special kind of special The single-hole forward extrusion production method of the split combined die can produce high-performance aluminum automobile chassis profile products with good comprehensive performance and meeting user requirements.

The 6061 alloy belongs to the Al-Mg-Si series alloy. Its tensile strength and yield strength usually increase with the increase of the content of Mg2Si and excess silicon in the alloy, and the quenching sensitivity will also increase accordingly. Although excess silicon has good extrudability and strength properties, it is prone to intergranular corrosion and pitting corrosion, which deteriorates secondary processability, toughness and weldability.
