Black soft iron wire has good elasticity and flexibility, and its softness and hardness can be controlled during annealing. It is made of high-quality iron wire and is mainly used in the construction industry as binding wire and wire.
Production process: Hot metal billets are rolled into 6.5mm thick steel bars, also known as wire rods, and then placed into a drawing device to draw wires of different diameters. The diameter of the drawing disc is gradually reduced, and various specifications of iron wires are made through processing techniques such as cooling, annealing, and coating. It contains components such as iron, cobalt, nickel, copper, carbon, zinc, and other elements.
Product features
The main wire diameters are 5 # -38 # (thread diameter 0.17-4.5mm)
Traits: softer than ordinary black iron wire, stronger flexibility, uniform softness, and consistent color.
Usage: Mainly used in construction, mining, chemical industry, welding net, welding clothes rack, reprocessing, etc. After annealing, the iron wire becomes softer and its flexibility increases, making it more effective for building wire binding and steel reinforcement binding.
Packaging: The packaging of black iron wire is the same as that of galvanized wire, which is divided into inner plastic and outer hemp, inner plastic and outer weaving. First, wrap a thin layer of plastic around the wire, and then wrap it in a hemp or woven bag! 0.5kg ,1kg ,5kg,10kg ,20kg,25kg to 500kg per coil.also accept customized
