Black Annealed Iron Wire Character:
Anti-corrosion and anti-oxidization.
Cost-saving.
Excellent flexibility and softness.
Durable and long service life.
Annealed wire also has increased corrosion resistance compared to non-annealed wire. The heating and cooling process causes changes in the metal’s structure, making it less susceptible to oxidation and rusting when exposed to moisture or other corrosive elements.
Annealed wire offers numerous advantages over non-annealed wire due to its increased flexibility, ductility, corrosion resistance, and electrical conductivity. These properties make it a popular choice among manufacturers for a wide range of applications requiring high-performance materials.
Black Annealed Iron Wire Application:
As tie wire in daily life binding.
Baling wire in building fixing and reinforcement.
Material of fences and meshes.
Binding wire for tying flowers.
Binding wire for tying landscapes in garden.
Made into handicrafts.
