Abstract
A head drum for supporting a magnetic head for magnetically recording information on and reproducing information from a magnetic tape includes an inner body of an aluminum alloy, and a wear-resistant layer of a sintered powdery alloy disposed around an outer circumference of the inner body in at least a region for sliding contact with an elongate magnetic recording medium. The wear-resistant layer has a thickness of at least 0.2 um, and the sintered powdery alloy comprises a powdery alloy of 17 to 38% of Si, 0.5 to 5% of Cu, 0.3 to 5% of Mg, and the remainder of aluminum.
