Iron wire is known for its toughness and durability. Its strength comes from the inherent properties of iron, and after processing, the iron wire has higher tensile strength and toughness. This allows the iron wire to withstand significant pressure and tension, making it less prone to breakage or deformation. At the same time, iron wire also has a certain degree of corrosion resistance, which can be used for a long time in humid or harsh environments without easily rusting.
