  • Nickel-copper-beryllium alloy compositions
    Patent number: 6093264
    Abstract: A nickel-based alloy composition is disclosed comprising from about 0.05 to about 3 percent by weight beryllium; from about 1 to about 40 percent by weight copper; no greater than about 10 percent by weight chromium, the balance being nickel. The alloy composition may be adjusted to achieve a high, as-cast hardness alloy over a wide range of alloy component contents, or a moderate, as-cast hardness alloy useful for forming articles such as golf clubs which has relatively constant mechanical properties over a wide range of copper contents.
    Type: Grant
    Filed: August 2, 1999
    Date of Patent: July 25, 2000
    Assignee: NGK Metals Corporation
    Inventors: Charles Walter Hershberger, Dennis Hall
