Flux
Argentium Silver is firescale free, therefore, it is only necessary to flux the seam to be soldered, rather than applying flux to the whole article. Our customers have recommended using the following fluxes with Argentium Silver:
- MY-T-FLUX (supplied by Rio Grande , USA)
Battern's Flux - Prip's Flux
N.B. Handy or Easy-Flow type fluxes can cause staining with Argentium® Silver.

Soldering tips
Heat/colour recognition of Argentium 930 Silver: When soldering Argentium® 930 Silver, it is important to remember that the metal displays a paler colour than standard sterling silver at red heat. To avoid overheating, it is recommended that annealing and soldering applications should be carried out in a shaded area.
Argentium 930 Silver can become brittle at red-hot temperatures: Make sure that the silver is well supported during heating applications and simply wait a few seconds for the red heat to disappear before touching, moving or quenching. This is easier to see in a shaded area.
Charcoal soldering blocks are not recommended with Argentium Silver alloys: Charcoal produces a reducing atmosphere that inhibits the formation of the protective germanium oxide surface layer during annealing and soldering operations.
