The lamellar structure of copper powder gives technical lubricants excellent tribological characteristics. In addition, the electrical and thermal conductivity and the heat resistance of the metal enhance all of the lubricant’s properties.
Lamellar copper powders for use in contact materials, lubricants and in the chemical industry are produced when copper powder atomized in air is processed in the following ball milling procedures.
|Apparent density [g/cm³]||Copper content [%]||D 50 value [µm]||flowability||Grease content [%]||Sieve analysis [%]||Application|
