Zirconium-based amorphous alloy, spectacle frame and method for constructing the same

Abstract

A zirconium-based amorphous alloy includes 10.0 to 15.0 wt % copper, 7.0 to 13.0 wt % nickel, 5.0 to 8.0 wt % niobium, and 2.0 to 5.0 wt % aluminum, with the remainder zirconium and unavoidable impurities. A method for constructing a spectacle frame, comprises forming a nickel-niobium alloy, a weight ratio of the nickel and the niobium of which is being in a range between 7:8 and 13:5, melting the nickel-niobium alloy, mixing the molten the nickel-niobium alloy with 55.0 to 75.0 wt % Zr, 10.0 to 15.0 wt % Cu, and 2.0 to 6.0 wt % Al to form a master alloy, melting the master alloy, and molding the master alloy into a spectacle frame.
