  • Control of oxide growth on molten aluminum during casting using a high moisture atmosphere
    Patent number: 7267158
    Abstract: A method of producing aluminum castings which includes the steps of casting a molten alloy, contacting the surface of the molten alloy with a humidified atmosphere and solidifying the alloy. The method is particularly suited for aluminum-magnesium alloys such as AA 5XXX and 7XXX series alloys. In addition to reducing the thickness of the surface oxide layer formed during casting, the method also provides improved surface quality of cast products and reduces subsequent remedial re-work or scalping. An improved aluminum-magnesium cast alloy product is also disclosed.
    Type: Grant
    Filed: July 2, 2003
    Date of Patent: September 11, 2007
    Assignee: Alcoa Inc.
