    Abstract: An aluminum alloy that can be cast into structural components wherein at least some of the raw materials used to produce the alloy are sourced from secondary production sources. In addition to aluminum as the primary constituent, such an alloy includes 5 to 14% silicon, 0 to 1.5% copper, 0.2 to 0.55% magnesium, 0.2 to 1.2% iron, 0.1 to 0.6% manganese, 0 to 0.5% nickel, 0 to 0.8% zinc, 0 to 0.2% of other trace elements selected from the group consisting essentially of titanium, zirconium, vanadium, molybdenum and cobalt. In a preferred form, most of the aluminum is from a secondary production source. Methods of analyzing a secondary production aluminum alloy to determine its constituent makeup is also disclosed, as is a method of adjusting the constituent makeup of such an alloy in situations where the alloy is out of tolerance when measured against its primary source counterpart.

    Abstract: A method of transferring molten metal to a die casting mold is disclosed. The method includes providing a ladle with a dip well and a dispensing nozzle having a fluid metal filter formed therein as well as providing a receptacle fluidly between the ladle and the mold. Further the method includes delivering the molten metal from the ladle to the receptacle by positioning an exit face of the dispensing nozzle over the receptacle and rotating the ladle such that the exit face of the dispensing nozzle is repositioned proximal the bottom of the receptacle and conveying the molten metal that has been delivered to the receptacle into a mold cavity that is placed in fluid communication therewith.

    Abstract: A device and method for transferring filtered molten metal to a die casting mold. The device and method include a casting filtration system that includes a funnel and a continuously replaceable filter placed fluidly between a molten metal source and a casting mold. Both the funnel and filter are automatically moved into cooperation with a molten metal receptacle such as a shot sleeve prior to each casting operation, and then automatically moved out of the way so that pressurization of the filtered molten metal may take place in the receptacle. In addition, the filter may be formed on a continuous strand such that indexed movement of the strand will advance the used portion of the filter out of the way to make room for a new unused filter portion that will be ready for a subsequent repeated casting operation.
