black annealed wire

Material:low carbon steel wire Wire Dia:0.3mm-8.5mm Tensile Strength:330-550N/MM2 Management Certification : ISO 9001:2000 The Black Annealed Wire has a good elasticity and flexibility , and its degree of hardness can be controlled during annealing. It is made of high quality iron wire , mainly used in the construction industry as a bundled wire and binding wire. Silk number is 5 # -38 # ( wire by 0.17 - 4.5mm)  that is softer than the ordinary black iron wire , stronger flexibility , softness uniform , consistent chromaticity . 

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 .

Application: 

Black annealed wire is mainly used as industrial wire, construction wire, industrial bale tie wire and constructional tie wire, etc.

Package:

 In coils and from 0.7kgs/coil to 800kgs/coil then 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.
