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 Solders:

• MY-T-FLUX™ (supplied by Rio Grande, USA)
• Prip’s Flux
• Battern’s Flux
• Paste fluxes

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 should not be touched or quenched when it is at red-heat: this can cause the alloy to be brittle. Simply wait a few seconds for the red-heat to disappear before touching or quenching (this is easier to see in a shaded area).

Argentium Silver solders are manufactured by Stern-Leach, USA. These solders are available to purchase from our listed suppliers on our website: http://www.argentiumsilver.info
