Abstract
A method for casting an aluminum wheel comprises preparing a melt having a predetermined chemistry and including silicon in a range from 8.5 to 10% mass and aluminum; degassing and refining the melt; adding a grain refiner including aluminum-titanium-vanadium-boron (Al—Ti—V—B) and a master alloy to the melt; and casting the aluminum wheel.
Claims20
A method for casting an aluminum wheel including a hub, a rim, and a plurality of spokes connected the hub to the rim, the method comprising:
- preparing a melt having a predetermined chemistry and including silicon in a range from 8.5 to 10% mass, iron (Fe) in a range from 0.1 to 0.25% mass, and aluminum comprising greater than or equal to 70% mass scrap aluminum;
- degassing and refining the melt;
- adding a grain refiner including aluminum-titanium-vanadium-boron (Al—Ti—V—B) and a master alloy to the melt;
- and
- casting the aluminum wheel,
- wherein the aluminum wheel has an average grain size of a spoke region in a range from 50 μm to 250 μm.
