  • CENTRIFUGAL CASTING

    CENTRIFUGAL CASTING

    The centrifugal casting can be used for metal matrix composite (MMC) melts. For example if stir cast aluminium/graphite melt is poured in the rotating mould, graphite particles will segregate in the inner periphery of the centrifugal casting as graphite density is lower than aluminium. Thus such casting can be employed for bearing appliions5.
