Jun, H.J. Ahmad, A. Sallih, N. Lajis, M.A. Shamsudin, S. Aluminium alloy 7075 is chosen as the material to be investigated to replace stainless steel as the material of hyperthermic needle. Hot Direct Extrusion process is famous for reducing the size of the grain to enhance the mechanical properties of the alloy. The process parameters are investigated through several extrusion process related researches. Speed of extrusion was operated within pre-heat temperature of 350 to 450 ºC and pre-heat time of 1 to 2 h. The effect of extrusion parameters were analyzed by using design of experiment method including Taguchi method and Full Factorial method. Furthermore, density test, Vickers hardness test, compression test and microscopic visual inspection such as optical microscopic and scanning electron microscopic (SEM) were conducted.
