    Silver solder

    Ag-Cu-Zn alloy, mainly used for brazing and has a relatively low melting point, high fluidity and a high corrosion resistance. The possible compositions are marked with * in the table. By adding P, Ni, Cd, Mn and Sn, the melting point can be reduced and the fluidity increased.
