Abstract As powder metallurgy usage broadens, the amount of challenging parts with higher densities increases. More sophisticated powder mixes and high performance lubricants are therefore required for such parts. In the case of high-density parts, the lubricant content must be minimized as much as possible in order to reach higher densities. Lubricants for high density applications must therefore provide the same lubrication performance at much lower concentrations than traditional lubricants. This paper presents the compaction and ejection behaviour of new lubricant systems specifically designed to reach densities above 7.3 g/cm3. These lubricant systems were evaluated under real production conditions. The physical and sintered properties of mixes produced from such lubricants are also discussed. The results are compared to commonly used lubricants in the PM industry.
