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.
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.
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.
The grain is a base metal formula with a lower melting temperature than nickel alloy.
• Cast temperature is approximate; adjust for your particular alloy and application.
• Due to the manufacturing process of casting grain, the grain will vary in shape and size.
