Alpaca Alloy Casting Grain

Formulated by Legor® Group, this casting grain is the perfect an alternative to sterling silver for casting samples and master models. It delivers gray color that you can easily plate. Because it is professionally produced, you can count on consistent, repeatable quality and composition over time. Priced individually; each package contains approximately 4.4 lbs. Applications Any casting method. Casting and Cleaning In general, your casting temperature should be 100˚F (37.7˚C) above the liquidus point (somewhat hotter if the castings are intricate). Use a small amount of high-quality flux when melting with an open flame. We recommend Matt’s Casting Flux™. For further cleaning, mechanical means are recommended. Re-Using If you plan to re-use bronze castings, remove the copper oxides from the surface in a pickling solution or by mechanical means. We recommend a minimum 1:1 ratio of new grain to used bronze. All re-used bronze should be clean and free of debris. Composition The grain is a base metal formula with a lower melting temperature than nickel alloy.
