Effect of Compaction Pressure on Physical Properties of Milled Aluminium Chip (AA6061)

AA6061 alloy is widely used material in the automotive and aerospace industries. Consequently, more of the metal has been lost during manufacturing. The present study is aimed at investigating of physical properties of the milled Aluminium chip for this alloy according to change compaction pressure. Three values of compaction pressure were taken (5, 7, 9) tons. On the other hand, four types of particle size were chosen (25, 63, 100, mix) m. The results were showing that the density and Microhardness increased with increasing the compaction pressure, while the porosity and water absorption decreased with increasing the compaction pressure. It can be concluded, (9 ton) is the best choice. On the other hand, the type DI (mix) was given the best result for density, porosity and water absorption compare with others according to particle size.
