Which of the following components can be manufactured by powder metallurgy technique?

Advantages of Casting are: (I) Can create complex part geometries, 3-D shapes (II) Can create both external and internal shapes and large hollow shapes (III) It is a near net shape process for small to large parts (IV) Very good mechanical strength can be obtained for as-cast component
