摘　　要：严格控制镁、硅含量,向6063铝合金中添加一定量的混合稀土,采用工业生产设备熔炼稀土改性铝合金6063D-RE,研究其铸态组织和挤压性能。结果表明,添加稀土后,铝合金的挤压性能提高,挤压时所需挤压力减小,模具寿命提高,挤压速度变快,生产效率提高。稀土对铝合金组织有良好的改性作用,有少量的富含稀土相析出。Adding a certain amount of rare earth into 6063 aluminum alloy and strictly controlling the contents of the magnesium and silicon, the 6063D-RE modified aluminum alloyis produced by using the industrial production equipment, then the as-casting microstructure and extrusion properties of the 6063D-RE alloy are studied . The results show that：the properties of the alloy is raised, during the extruding process, the extrusion force, required is reduced, the life of the mold and the rate of extrtiding are improved, and the productivity gets more efficient. RE has a good modifying effect to the microsture of aluminum alloy. There are a small amount of rare earth-rich phases precipitated after rare earth added.
