In this study, the extrusion process of 6xxx series aluminum cast alloy for high speed train interior or exterior parts are developed. For casting, selection of optimum alloying elements, dissolution technology, de-gassing process, production of molds conforming to the conditions of use, development of casting process control technology for various shapes and materials are performed for the development of high-quality, high strength aluminum alloys. The development of more high farmable extruded aluminum casting alloys for interior or exterior materials has been the scope of this study. The extruded die design was performed for the 6063, 6061 and 6N01 alloy profiles and extrusion test was executed. From these results, the extrusion conditions such as extrusion pressure following as billet temperature and materials were carefully examined.
