Caster's Yellow Brass Chunks

This bass casting material comes in chunk form; it offers better fluidity in its molten state for more precisely detailed castings. The metal has a bright yellow color and is a great choice fashion and costume jewelry, as well as for larger non-jewelry pieces. Because it is professionally produced, you can count on consistent, repeatable quality and composition over time. Sold by the pound. 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 yellow brass 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 brass. All re-used brass should be clean and free of debris. Composition The casting material is composed of composed of 63% copper, 1% lead, and various amounts of zinc and tin.
