The Analysis of Pressed Cups Producing Possibilities from Rolled Bimetallic Al-1050 + Cu-M1E Sheets

“…The first stage is to obtain a permanent connection of two metals, or alloys. The second is plastic-shaping of the combined blank [1][2][3][4][5][6][7][8][9][10]. At this stage, often several plastic work-processes are carried out, the purpose of which is to finally shape the multilayered product [11][12][13][14][15][16][17][18][19][20][21][22][23][24].…”

“…This was the primary reason why the process of multi-operational drawing of thin bimetallic Al-1050 + Cu-M1E sheets has been taken into consideration in this work. This study also discusses two pre-pressing processes, i.e., explosive-welding and requiring continuous control of the asymmetrical rolling process (ASR) [3,9,10,17,23,33,34].…”

“…This is clearly visible in the energy and electronics sectors, where products based on aluminum and copper are more commonly used. To date, the process of shaping flat, multilayer products has been extensively described in many papers [9,10,18,34]. The combination of aluminum and copper is quite commonly used in industrial conditions [2, [7][8][9].…”

The combination of aluminum and copper is quite commonly used in industrial conditions [2, [7][8][9]. In energy and electronics systems, metal composites in the form of aluminum-copper elements (Al/Cu) are very often used.…”

“…The presented example of the implementation of Al/Cu bimetal refers to the condition where copper is the outer layer in the finished product. As mentioned above, a problem that occurs very often in the manufacturing process of multilayer products, is the occurrence of intermetallic phases [7,[9][10][11][12][13][14][15][16][17][18][19][20]25,27,[29][30][31][32][33][34]. In bimetals of the Cu/Al type, a very commonly observed phase is CuAl 2 (gray-brown area in Figure 3).…”
