Pure iron nails are made from high-purity iron, typically containing over 99% iron with minimal impurities. This composition lends them unique characteristics, such as excellent corrosion resistance and malleability. Unlike steel nails, which may include alloying elements like carbon, pure iron nails offer a softer material that can be easily manipulated during the manufacturing process. Their structure allows for exceptional ductility and flexibility, making them ideal for various applications.
