Cast Iron Scrap is a form of ferrous scrap consisting of various used cast iron products. This material is typically sourced from old industrial machinery, radiators, bathtubs, manhole covers, and automotive parts like engine blocks and manifolds. Unlike steel, cast iron has a high carbon content (typically 2-4%), which makes it hard and brittle. In the recycling industry, this scrap is highly sought after by foundries and mills that specialize in producing new cast iron products. It is processed by breaking it into manageable sizes for re-melting in furnaces.
