Get durable, tarnish-resistant castings with anti-oxidant, anti-firescale Argentium® 935 PRO.

Exceptional fluidity makes this grain ideal for filigree and detailed designs, small items, flat surfaces and large surface areas. This grain also delivers beautiful results with stone-in-place casting.

Argentium® 935 PRO has the hardness and strength of an alloy with a higher silver content than sterling. This produces in a white, reflective color and durability that resists scratching.

Priced by the troy ounce (ozt.)

Argentium® 935 PRO casting grain is specifically engineered for investment casting with modern enclosed machines, but also performs well in open systems. It is the alloy of choice for those whose work is predominately investment casting.

Argentium® 935 PRO is made with copper and select deoxidizing elements. The alloy is guaranteed to be at least 93.5% pure silver.

Casting and Cleaning
It is important to use a flask temperature at least 85°F (30°C) below that normally used for sterling and never higher than 1,250°F. Use in dedicated crucibles to prevent accidental cross-contamination. Air-cool at least 15 minutes before quenching to achieve a hardness approximately equal to that of standard sterling. Using boric acid as a flux is recommended.

When re-casting Argentium® Silver, we recommend 1:1 ratio of new grain to used silver. For higher-quality pieces, a higher percentage of fresh grain ensures the best results. Remove the copper oxides from the surface in a pickling solution and then tumble with burnishing compound to remove any remaining debris. Adding traditional sterling to this grain is not recommend as doing so tends to dilute the properties of Argentium Silver.
