FIELD: metallurgy.
SUBSTANCE: invention relates to metal powder industry, particularly, to items production from aluminium-based fine powders. Aluminium powder is mixed up with 0.3-0.6 wt % of process lubricant - 1-3% water-glycerin gels of the cleaned sodium carboxymethyl cellulose. Then, pressing is conducting in compression mold at 75-95°C within pressure range 350-600 MPa at (0.5-1.5)103 m/s.
EFFECT: method allows for reducing dust-producing capabilities of aluminium powder and increasing items strength.
