To obtain a metallic porous body with improved wear resistance and a light alloy composite member using such body by nearly uniformly dispersing or alloying particles for improving material on a skeletal metal in a porous body having communicative pores.
A skeletal metal is desirably a metal selected from a group composed of Ni, Fe and Cu and/or an alloy selected from a group composed of Ni, Fe and Cu group alloys, improving the material of a metallic porous body by forming an alloy with a cast-in aluminum alloy for example. In improving wear resistance, it is desirable to use a ceramic particle or a metal that alloys with the skeletal metal at the time of sintering. For example, it is advisable that the skeletal metal is Ni and/or Ni group alloy, that the particle for improving material is Cr, and that the Cr content is 25-35 wt.% against the metallic porous body. The ceramic particle preferably contains one kind or more of SiC, Al2O3, etc., by 5-30 volume % against the metallic porous body.
