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 composed of 58.25% copper with various amounts of zinc, iron, manganese, aluminum and tin.
