Black Annealed Wire

 

 

    Key Features

  • Superior Flexibility​ — Dead-soft annealed quality, easy to knot tightly without spring-back or fracture.
  • Uniform Diameter & Surface​ — Precision drawn with smooth black oxide coating for consistent performance.
  • Good Tensile Strength​ — Maintains structural integrity while staying pliable (300–500 MPa typical).
  • Optional Oil Coating​ — Light anti-rust oil available to protect against oxidation during storage & transport.
  • Cost-Effective​ — More economical than galvanized wire for indoor or temporary outdoor use.
  • Customizable​ — Available in various wire gauges, coil weights, and packaging per customer request.

Description

Black Annealed Wire​ is manufactured from high-quality low carbon steel wire (Q195/SAE1008) through the process of cold drawing and thermal annealing. The annealing treatment relieves internal stress and softens the wire, giving it exceptional flexibility, ductility, and a uniform black oxide finish. It is easy to bend, twist, and tie by hand or machine without breaking, making it an economical and reliable solution for construction rebar tying, baling, packaging, agriculture, and daily binding applications.
