Nacional de Grafite is highlighting Supergraf, a high-purity carbon additive that promises to transform the way carbon is incorporated into iron and steel alloys in the steel and foundry sectors.
The addition of carbon is a critical stage in the manufacture of steel and cast iron, as it directly influences the final properties of the material, such as strength, ductility and hardness. However, many of the fuels available on the market are derived from industrial waste, which can present high levels of impurities, environmental risks and even operational instability. These factors compromise the predictability of processes, increase production costs and require greater control to guarantee quality and safety. Furthermore, in a scenario where sustainability and energy efficiency are priorities, the demand for safer, more stable and environmentally responsible solutions is growing.
Supergraf offers a superior response to these challenges. Produced from high-purity natural crystalline graphite, extracted and processed in Brazil, the product is a high-performance, reliable and sustainable fuel. Its high carbon content and absorption guarantee efficiency in foundry and steelmaking processes. The very low impurity content ensures superior quality and less risk of contamination. High thermal stability is essential to withstand extreme furnace conditions. Low humidity increases operational safety and, as it is of natural origin and not derived from industrial waste, it eliminates environmental and explosive risks.
These characteristics make Supergraf a reliable solution for different types of cast iron such as gray, nodular, white, malleable and vermicular, as well as special steels. The product also finds applications in cored wire and in brake components such as pads and shoes.
Sustainability is in Nacional de Grafite’s DNA. By working with a natural product that is not derived from waste, the company eliminates environmental risks and significantly reduces its customers’ carbon footprint. In addition, the company invests in international quality and sustainability certifications, ensuring that its processes are aligned with the best global practices. The verticalization of production is also a key factor: controlling the entire cycle, from the mine to the final product, allows for greater efficiency in the use of resources, less waste generation and total traceability.
