Black annealed wire, also known as soft annealed wire,binding wire,tie wire is a popular choice for tying wire in the construction industry and home uses. It’s made of low carton steel through cold drawing,high temperture annealing ,After annealing, the iron wire becomes softer and its flexibility increases, making it more effective for binding construction wires and steel bars. It’s Mainly used in construction, mining, chemical industry, welding mesh, welding hanger, reprocessing, etc.
1.24mm Black Annealed Wire: Materials, Features, Applications & Normal Packing
- Materials: Low-carbon steel (Q195/Q235), via cold drawing + controlled annealing (800–900°C heating + slow cooling) to form a black oxide film; optional light oil coating for basic rust protection .
