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.
Specification
Black annealed iron wire, known for its softness and flexibility, is a versatile and widely-used product in the hardware industry. Made from low-carbon steel, the black annealed iron wire undergoes a process of annealing, where it's heated to a high temperature and then slowly cooled. This process enhances its malleability and durability. Its black oxide finish provides a layer of protection against rust. This black annealed iron wire is commonly used in construction for tying rebar, in agriculture for baling and other woodworking projects. Its high quality, affordability, and adaptability make the black annealed iron wire a popular choice among various industries.
