Black Annealed Iron Wire

1. Product Overview

Black Annealed Iron Wire is a soft, flexible low-carbon iron wire produced through controlled annealing to enhance ductility, workability, and handling performance. It is widely used for construction tying, baling, binding, packaging, agricultural applications, and general industrial fabrication. Its consistent mechanical properties, easy bending, and reliable tensile performance provide an efficient alternative to untreated or less workable wire products. As a high-volume industrial consumable, it supports cost-effective sourcing across construction, manufacturing, agriculture, and logistics operations.
