Abstract
Disclosed are PA0 (1) a composite material of aluminum powder containing spherical carbon particles; PA0 (2) a composite material of aluminum powder having a good self-lubricity and a high wear resistance and consolidated with a mixture of PA1 (i) 100 parts by weight of aluminum particles of about 1 to about 200 .mu.m in mean particle size; and PA1 (ii) about 1 and about 100 parts by weight of spherical carbon particles of about 1 to about 50 .mu.m in mean particle size; and PA0 (3) a composite material of aluminum powder having a good self-lubricity, a high wear resistance and a high strength and consolidated with a mixture of PA1 (i) 100 parts of aluminum alloy particles containing about 0.3 to about 15% by weight of magnesium and having a mean particle size of about 1 to about 200 .mu.m; and PA1 (ii) about 1 to about 100 parts by weight of spherical carbon particles having a mean particle size of about 1 to about 50 .mu.m.
