Black Annealed Wire Offers Excellent Flexibility and Softness Through the Process of Oxygen Free Annealing

Material: low carbon steel wire or iron wire.
Surface treatment: a light coating of black soot.
Wire diameter: 5–0.15mm (wire gauge 6# to 38#).
Tensile strength: 300–500 N/mm 2 .
Elongation: 24%.
Type: coil wire, spool wire, big package wire, cut wire and u type wire

Black annealed wire is made from low-carbon steel and undergoes a dual-treatment process of wire drawing and thermal annealing. The annealing process returns some of the flexibility to the wire lost during the drawing process. Compared with black iron wire, black annealed wire is more softer and has higher flexibility.

Black annealed wire is mainly processed into coil wire, spool wire or big package wire. Or further straightened and cut into cut wire and U type wire.

Black annealed wire is a common used metal wire in our life. e.g. for weaving, construction, industrial and everyday binding.
