Materials:
The main materials of Black Annealed Wire are iron wire and carbon steel wire.
Technology:
Black annealed wire material is normally provided by the Q195 type drawing rod into the black wire.The selected raw materials after 1000 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.
