To improve the physical and contact properties of fine silver melt-metallurgical produced silver alloys are used ''<xr id="tab:tab2.13"/>(Table 2.13)''. By adding metal components the mechanical properties such as hardness and tensile strength as well as typical contact properties such as erosion resistance, and resistance against material transfer in DC circuits are increased <xr id="tab:tab2.14"/> (Table 2.14). On the other hand however, other properties such as electrical conductivity and chemical corrosion resistance can be negatively impacted by alloying <xr id="fig:fig2.47"/> (Fig. 2.47) and <xr id="fig:fig2.48"/> (Fig. 2.48).
