    As long as the spinning shaft does not create cavitation the spinning action will create a pathway for the trapped gasses of the molten aluminum to escape
    Never try to tell me it can't be done

    You bubble Argon through it. That helps displace the trapped Hydrogen gas.

    The stirrer is usually Graphite. Molten aluminum is very corrosive, and reacts with steel and stainless steel.
