FIELD: powder metallurgy.
SUBSTANCE: invention relates to powder metallurgy, particularly, to aluminium composite materials for laser melting. It can be used in various industries in the manufacture of products using additive laser technologies. Aluminium composite material for laser melting contains the following, wt.%: submicron ceramic particles SiC 8.5-13.5; particles of titanium alloy BT5 12-15 and powder of aluminium alloy Al-Si 71.5-79.5.
EFFECT: providing hardness at room temperature 164-213 HV0.05 and temperature 200-400 °C 195-213 HV0.05.
