Black Annealed Wire is also called
Black Wire. Black Annealed Wire gets its name from its plain black
color. Black Annealed Wire offers excellent flexibility and
softness through the process of oxygen free
annealing.

Technology
Black annealed wire material is normally provided by the Q**5 type
drawing rod into the black wire.The selected raw materials after
***0 degrees high temperature calcination keep enough time, then to
appropriate cooling rate.The purpose is to reduce the hardness,
improved machinability; elimination of residual stress, stable
size, reduce the deformation and crack tendency; grain refinement,
restructuring the organization, eliminate defects in the
organization.
Package:
In coils and from 0.7kgs/coil to **0kgs/coil each coil to be
wrapped inside with PVC strips and outside with Hessian cloth or
inside with PVC strips and outside with weaving bag also can be
made according to our customers\'
requirements.
