  • Master alloy hardeners
    Patent number: 6123899
    Abstract: This invention relates to master alloy hardeners for use in preparing aluminum base alloys. The respective concentrations of the alloying elements in the master alloy hardener are a multiple equal to or greater than 2 of the concentrations of such elements in the base alloy, and the ratios of the alloying elements in the master alloy hardener to each other are the same as the ratios of the alloying elements in the base alloy. After the aluminum base alloy and the concentration of each alloying element therein are identified, a desired multiple of such concentrations is determined. An aluminum master alloy is prepared that contains the alloying elements at concentrations equivalent to such multiple of the corresponding concentrations of the elements in the base alloy. The master alloy hardeners are added to commercially pure aluminum to provide the desired base alloy.
    Type: Grant

  • Aluminum master alloys containing strontium, boron, and silicon for grain refining and modifying aluminum alloys
    Patent number: 5230754
    Abstract: Improved aluminum master alloys containing strontium and boron are provided for simultaneously modifying and grain refining Al alloys, and in particular, hypoeutectic Al-Si alloys. The improved master alloy contains, by weight percent, about 0.20-20% Sr, 0.10-10% B, and the balance Al with impurities. The master alloy may also contain about 0.20 to about 20% Si by weight percent. The master alloys have a high degree of ductility for purposes of forming continuously rolled master alloy rod stock.
