Graphite electrodes are primarly used in the secondary production of steel EAF and ladel furnaces. Our graphite electrode stock has additional applications, such as melting products in smelting furnaces, non ferrous metals, ceramic products, and to recycle waste. There as several grades of graphite electrodes, and matching the grade with the application can lower your melting cost. Please call Graphite Australia, if you want us to analyze your melting systems for the lowest cost alternative.
