Pure Aluminum - an overview | ScienceDirect Topics

Pure aluminium powder and pure copper powder can be used to produce an Al–Al 2 Cu composite via FSP. Cu reacts completely with Al and forms Al 2 Cu during FSP. In addition, copper oxides (CuO and Cu 2 O), which result from oxidation during sintering in air, disappeared after FSP, which might be a result of the reaction between Al and copper oxides to form Al 2 O 3 and Al 2 Cu (Figure 9.9
