Coil weight:*5kg, *0kg, **0kg or according to customers request. Elongation: 8% - *5%
Features:Black annealed wire offers excellent flexibility and softness due to its oxygen-free annealing process. It is rust proof within 6 months without any oil coating.
Application:
Black annealed wire is mainly used as industrial wire, construction wire, industrial bale tie wire and constructional tie wire, etc
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 calcinations keep enough time, then to appropriate cooling rate. The purpose is to reduce the hardness, improved mach inability; elimination of residual stress, stable size, reduces 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
