Anthracite iron is not a widely recognized term in metallurgy or material science, but it appears to refer to a type of cast iron that is characterized by its high carbon content, similar to anthracite coal, which is known for being a high-carbon, high-energy fossil fuel. In general, cast iron is classified into several types based on the form of carbon it contains, such as gray iron, ductile iron, and white iron.
