<p> Cast Iron and Steel are both very popular materials. Cast Iron is appreciated for being very brittle, making it easier to sort into desirable quantities as scrap. It also has high fluidity and castability, and is highly resistant to wear-and-tear. This makes it an attractive material for engineers. Steel is also renowned for its durability, as an alloy of Iron. Its great weldability and resistance to rusting make Steel a good scrap metal to get your hands on.</p> <p> [Photo credit: Johannes Hemmerlein]</p>
