Black annealing wire is a kind of soft iron wire product made of low carbon steel cold drawing,heating,constant temperature，heat preservation and other processes.
Iron wire is used in different ways, and the composition is also different.It contains iron, cobalt,nickel, copper, carbon, zinc, and other elements.
Application:
Building and fire organizations for black fiber cloth such as silk and silk tie made from high-quality wire,primarily for the construction industry and for tying silk tie lines,20#,21#,22# issue of a wire,producing and also required.
Materials:
Made by standard low carbon steel wire through the process of wire drawing,acid washing,rust removing and annealing.Black annealling wire and all other wire mesh are manufactured by wire rod. The type of wire rod is Q195, element composition is as follows: C≤0.07; S≤0.023; Si≤0.09; Mn≤0.32; P≤0.025.Because This type of wire rod has less Impurities, Q195 is fit for drawing.
Low carbon black wire Feature:
It can offer excellent flexibility and plasticity,can be used widely.
Tensile Strength:35-70kg/square
Coil weight:0.1-800kg/coil
Low costs and economy
