  • Aluminum Alloy Refiner Material and Preparation Method Thereof
    Publication number: 20160298217
    Abstract: The present invention provides an aluminum alloy refiner, which is characterized by being an amorphous alloy comprising 40 to 60 parts of Zr, 25 to 45 parts of Cu, 1 to 15 parts of Al, 1 to 10 parts of Pd and 1 to 10 parts of Nb in terms of mass fraction. The refiner provided by the present invention can be used to favorably refine crystal grains as well as improve the mechanical property of the aluminum alloy to a certain extent. Moreover, the intermediate alloy improves the strength and plasticity of the alloy, and a refined A356 aluminum alloy is very suitable for the manufacturing of automobile wheels.
