  • Aluminum-beryllium alloys having high stiffness and low thermal expansion for memory devices
    Patent number: 5840135
    Abstract: Articles of manufacture are made of aluminum-beryllium alloys having substantially randomly distributed aluminum-rich and beryllium rich phases to provide substantially isotropic mechanical properties, such as high stiffness and low co-efficients of thermal expansion, whereby the articles of manufacture provide more rapid and accurate responses.
    Type: Grant
    Filed: May 2, 1996
    Date of Patent: November 24, 1998
    Assignee: Brush Wellman Inc.
    Inventors: Larry A. Grant, James M. Marder, Wayne L. Wright
  • Beryllium memory disk substrate for computer hard disk drive and process for making
    Patent number: 5800895
    Abstract: A Beryllium disk drive substrate is prepared using a Beryllium metal having a starting modulus of elasticity (stiffness) of about 4.2 times that of Aluminum, in which the beryllium is separated into circular disks and processed by a sequence of lapping, heat-treating under pressure, cooling under pressure and polishing steps which retains the desirable metallurgical characteristics of the starting metal and provides sufficiently high quality surface finish, thermal conductivity and low mass density, to enable improved rotational speeds, acceleration/deceleration rates and information packing density for demanding disk drive applications.
