The effect of die entry angles on the mechanical properties of extruded 6063 aluminum alloy at 32°C has been investigated. Mild steel and tool steel dies with entry angles of 15, 30, 45, 60, 75 and 90° were used for the extrusion and the extruded samples were subjected to mechanical and microstructural tests.
The results show that peak extrusion pressure and hardness of extrudes increase with increasing die entry angle which is in agreement with the literature. Good extrusion response by samples was observed in mild steel dies over that of tool steel at entry angles of 45,75 and 90°. Extrusion ratio for the die materials are practically the same except at 450 die entry angle where mild steel die exhibited superior extrusion ratio of 2.1 to that of tool steel of 1.8.
