Black annealed iron wire is a type of baling wire that has undergone an annealing process, which involves heating the wire to a specific temperature and then cooling it slowly. This process improves the wire's ductility and flexibility, making the black annealed iron wire easier to bend without breaking. The black annealed iron wire has a dark, almost black appearance due to the heat treatment, and it is often used in applications where high tensile strength and durability are required, such as in binding, tying, and general construction.
