Wire Materials
Iron wire or carbon steel wire.
The annealing of bare wire (wire which has simply been drawn) can be carried out in batches (bell-type furnace) or in line (in-line furnace).
Uses
Black annealed wire is mainly processed into coil wire, spool wire or big package wire. Or further straightened and cut into cut wire and U type wire. Annealed wire is used as tie wire or baling wire in building, parks and daily binding. Applied for home use and the construction.
