Continuous Black Annealed Binding Wire

Black Annealed Iron Wire is manufactured from high-quality low-carbon steel wire rods through precision drawing and controlled atmosphere annealing processes. The resulting dense oxide layer (Fe₃O₄) provides its distinctive dark appearance and basic rust resistance. The annealing treatment reorganizes the material's crystalline structure, significantly enhancing flexibility and ductility while maintaining essential tensile strength.

ours bends easily without spring-back, allowing for faster tying and bundling. Workers can complete more tasks comfortably and efficiently.Our precise winding on spools or uniform coiling ensures smooth feeding into automatic baling and tying equipment, keeping your production line running.Reduces workplace injuries. The smooth, oxidized surface and flexible nature significantly lower the risk of cuts and puncture wounds compared to harder or sharp-edged wires.
