Description of Black annealed wire

Material:

• Black annealed wire: Usually made from high-quality low-carbon steel like Q195 or Q235 as well6. After the annealing process, the internal stress of the wire is relieved, making it softer and more ductile compared to the black wire before annealing.

Wire Diameter (Size):

• Black annealed wire: The wire diameter typically ranges from 0.7mm to 5.5mm. Thinner black annealed wires are often used in the fields of agriculture (such as tying vines) and handicrafts, while thicker ones are used in construction for binding steel bars and other purposes.

Tensile Strength:

• Black annealed wire: After the annealing process, the tensile strength will be reduced compared to the original black wire. It is generally in the range of 350MPa to 550MPa. Although the tensile strength is slightly lower, its advantage lies in its increased softness and ductility, which is more conducive to operations such as bending and tying

Surface Treatment:

• Black annealed wire: Usually coated with rust-inhibiting oil to prevent rust and corrosion, ensuring its durability and stability during storage and use.

Packaging:

• Black annealed wire is usually packaged in a way that combines an inner plastic layer and an outer hemp or woven bag. This packaging method can not only prevent the wire from being scratched or damaged but also has a certain moisture-proof and anti-rust effect, facilitating storage and transportation.
