Web11 Apr 2024 · Sintered aluminium-copper composite compacts of 2%, 4% and 6% copper content with different initial relative densities have been prepared by applying recommended powder compaction pressures. Webadded to the powder mixes to aid part ejection after mechanical compaction. However, the low bulk density of typical lubricants displaces valuable space preventing higher compacted green densities. Development of new lubricants that provide equivalent lubricity at much lower added levels would enable higher-density components.
