Figure 9 shows, that a thickness < 1,6 mm can avoid melting of aluminum during welding. Thus, a cost-benefit
optimization of the roll cladding at constant material properties is achieved, to avoid unnecessary disbursements and
weight for example in copper-aluminum connections of the electronic industry.
By using the numerical calculation to avoid the direct melt intermixture in the cladding interface, the rapid
intermetallic phase formation can be avoided. Despite the melting of aluminum, induced by heat conduction has to
be considered, that long term stable copper-aluminum connections are achievable.
