摘要： A metal composite material is obtained by casting a melt of a metal and has an outer surface on which aluminum borate particles maintained in a porous form are exposed. Therefore, an oil is allowed to infiltrate the aluminum borate particles on the outer surface, to be retained therein and to ooze out during sliding. As a consequence, the sliding life during which desired sliding properties are maintained can be significantly prolonged. The metal composite material may be produced from a preform obtained by sintering aluminum borate particles covered with electrically neutralized silica and alumina particles which have been formed by mixing a silica sol and an alumina sol with aluminum borate particles in an aqueous solution to cover aluminum borate particles.

The metal composite material (10) comprises a porous preform (1) containing porous aluminum borate particles (3) in which pores (3a) of the aluminum borate particles (3) are filled with a metal as a result of impregnation of a melt of the metal into the porous preform under pressure.
