<p>A high strength cast aluminum-beryllium alloy including magnesium represented by the formula (25-60 % A1) + (40-75 % Be) + (0.1-1.25 % Mg) + (0∫X∫5 %) + (0∫Y∫4 %) + (0∫Z∫0.75 %) = 100, wherein: X is at least one element selected from the group consisting of nickel, cobalt and copper; Y is at least one element selected from the group consisting of silicon and silver; and Z is at least one element selected from the group consisting of iron, titanium, zirconium, boron, antimony, strontium, germanium, scandium and the rare earth elements. A rotatable armset of an actuator consisting essentially of the above alloy. An actuator armset for a computer disk drive actuator (11) includes an armset (15), a plurality of suspensions (16), a plurality of transducers (17), a voice coil (18) and crash stop (20). The armset (15) includes a body (26). The body mounts brackets (28 and 29) which hold the voice coil (18) and a plurality of arms (30) positioned above and below each hard disk of the disk drive assembly.</p> |
