Previous studies have indicated that during the smelting of waste copper, the addition of suitable additives can significantly refine the grain structure of brass, eliminate internal inclusions, and enhance the overall performance of the alloy. Currently, most research on improving brass properties through additives focuses on primary copper ores, with limited attention given to how these additives affect scrap copper. This gap in research highlights the need for more investigation into the impact of additives on recycled copper materials. The sources of waste copper are highly diverse, making it challenging to achieve consistent results with a single type of additive. For instance, using rare earth elements alone may lead to dendritic grain formation, while excessive amounts can increase material costs. Boron alloys, although useful, tend to act slowly and offer limited grain refinement. Similarly, fluxes can help with degassing and slag removal, but their ability to remove impurities is limited when used alone, resulting in suboptimal performance. To address these limitations, our company has developed a strategy that involves combining different types of additives during the casting process of waste copper-based brass alloys. By optimizing the feeding method, we aim to improve the mechanical and physical properties of the final product. This approach has not been previously documented in existing literature. This innovative technique represents a new direction in the recycling and processing of waste copper, offering potential benefits in terms of cost efficiency, material performance, and environmental sustainability. Further research and testing are needed to fully understand the long-term effects and optimize the formulation of these mixed additives. We believe this method could play a significant role in the future of brass production from secondary raw materials.
