In the current work, 1 wt% Acrawax was premixed with the aluminium and magnesium powder as a lubricant for the first group samples. However, no wax was used for the second group specimens. As a sintering aid, 1 wt% Mg was added for both group materials. Compaction of the specimens was performed using a manual Carver hydraulic press and a floating rectangular die. First group specimens were pressed to green densities of 91.5 and 92.5% using pressures of 435 and 490 MPa, respectively. In the second group (no wax) samples, 93% green density was obtained using the similar compaction pressures. These conditions produced specimens whose dimensions were: 31.8 × 12.7 × 3.5 mm3. As a result, an increase has been seen on the density of sintered and green compacts with rising compacting pressure. Furthermore, addition of the wax negatively affected the transverse rupture strength of the alloy.
