Black annealed wire is also called black iron wire,soft annealed wire and annealed iron wire.It 
includes annealed wire and black oiled wire.Annealed wire is obtained by means of thermal
annealing. It’s made of carbon steel wire. Annealed wire offers excellent flexibility and softness
through the process of oxygen free annealing. And the black oiled wire is formed via the process 
of wire-drawing, anneal, and fuel oil injection. We can do it into straight cutting wire and also do
according to customers' special requirement.Black annealed wire, also known as oil painted black
 iron wire or black mild steel wire. Compared with galvanized wire, it is more economical to form coil
 wire, tie wire, or cut into straight wire. With more than 25 years producing experience, our black wire
 has the feature of anti-corrosion and anti-oxidization, cost-saving, excellent flexibility and softness,
 durable and long service life.Black Annealed Wire is deployed both in civil construction and in
 agriculture. Hence, in civil construction annealed wire, also known as ‘burnt wire’ is used for iron
 setting. In agriculture annealed wire is used for bailing hay. Meantime black annealed wire is widely
 used as tie wire or baling wire in building, parks and daily binding.Black annealed wire is mainly 
processed into coil wire, spool wire, big package wire or further straightened and cut into cut wire
 and U type wire.
Application:
As tie wire in daily life binding.
Baling wire in building fixing and reinforcement.
