→Hard-Silver Alloys
The attachment methods used for the hard silver materials are mostly close to those applied for fine silver and fine grain silver.
Hard-silver alloys are widely used for switching applications in the information and energy technology for currents up to 10 A, in special cases also for higher current ranges <xr id="tab:tab2.16Application Examples and Forms of Supply for Silver and Silver Alloys"/> (Table 2.16).
Dispersion hardened alloys of silver with 0.5 wt% MgO and NiO (ARGODUR 32) are produced by internal oxidation. While the melt-metallurgical alloy is easy to cold-work and form the material becomes very hard and brittle after dispersion hardening. Compared to fine silver and hard-silver this material has a greatly improved temperature stability and can be exposed to brazing temperatures up to 800°C without decreasing its hardness and tensile strength.
