Copper Pellets Rectangular Section are part of Goodfellow's range of copper pellets. Copper has excellent thermal and electrical conductivity, as well as good corrosion resistance and alloying ability. These properties make copper useful for electrical wiring, water piping, and industrial equipment. The pellets allow for precise dosing during alloy production or research experiments. Their rectangular shape provides a consistent surface area for reactions or heating. With Goodfellow's selection of sizes and purity levels, these copper pellets enable both large-scale manufacturing and lab-scale research.
