The black twisted iron wire is made of drawn Q195 wire as raw material. After selecting the raw materials, pass through a high temperature of about 1000°. And then cool to a suitable speed.
The purpose: Reduce hardness and improve workability; Reduce residual stress, stabilize size, reduce deformation and cracking tendency.

Application:
Black annealed wire is used in civil construction and agriculture. In agriculture, annealed wire is used for haystacks.
At the same time, the black annealing line is widely used as a binding or binding line in buildings, parks and daily bundling.
