In accordance with another aspect of the invention is an actuator armset of a disk drive system for movably positioning and supporting a transducer over a disk of the disk drive. The armset has a bore for pivoting about a spindle and comprises a magnesium alloy containing beryllium. A bearing assembly is interposed between the armset and the spindle, a flexible suspension being mounted at one end of the armset. Mounted to an opposing end of the suspension is a transducer.
