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 are made from high quality low carbon steel wire(Q195/Q235),which treated through an annealing process. This process, involving heating and slow cooling, enhances the wire's flexibility and durability. The black annealed iron wire's characteristic black finish is due to an oxide layer that provides rust resistance. Black annealed iron wire is favored in various industries such as construction for tying rebar, agriculture for baling purposes, and crafting for its ease of manipulation. Its key attributes include excellent softness, high durability, corrosion resistance, and cost-effectiveness, making the black annealed iron wire a go-to choice for many.
