WitrynaThe properties of Cu and Cu alloys can be enhanced by variations in composition and manufacturing methods. For example, lead (Pb) and tellurium (Te) can be added to Cu to improve machinability. Conversely, the presence of trace impurities in Cu and Cu alloys can adversely affect the properties of finished products. Witryna3 gru 2010 · The non‐metallic impurities were found to be less than 0.1% in the electroplated Cu with no effect on Cu electromigration lifetimes. Most of the metallic impurities reduced Cu interface and grain boundary mass flows and enhanced Cu lifetime, but Al, Co, and Mg impurities did not mitigate Cu grain boundary diffusion. Witryna1 gru 2024 · When the content of Cu impurity is increased to 1.0 at% and 5.0 at%, the size of primary particles becomes smaller and thinner, and the plate-like morphology has transformed into the sheet-like structure, indicating that Cu ions can promote the nucleation and growth of sheet-like primary particles. dysons creative process
