N2 - Grain size and homogeneity are influence to aluminium properties, Equal channel angular pressing (ECAP) can produce aluminium with ultra fine grain Size (UFG). The grain size is depends on ECAP Dies geometry (Channel angle Φ, Fillet radius ψ) and friction, taguchi method used to find the optimum dies geometry its can produce smaller grain size and homogeny. Modeling done with channel angels 90, 105 and 120°, fillet radius (inside) 1.5, 5,0 and 10 mm ; fillet radius (outside) 1.5, 5,0 and 10 mm and friction 0, 0,025 and 0,05. Modeling used L9 taguchi matrix, the most homogeny dies is ECAP dies with channel angel 105°, fillet radius (inside) 10 mm ; fillet radius (outside) 0 mm and friction 0,025.
