Introduction
Black annealed wire is a versatile and widely used material in construction, agriculture, and manufacturing industries. Known for its flexibility and strength, it is often favored for binding, tying, and crafting applications. Iran has become a notable supplier of black annealed wire, providing high-quality products at competitive prices. This guide explores the features, applications, and pricing of black annealed wire from Iran.
1. What is Black Annealed Wire?
Black annealed wire is low-carbon steel wire that undergoes a heat treatment process called annealing, which softens the metal, increases flexibility, and reduces brittleness. During manufacturing, the wire is coated with a thin layer of black oxide, giving it a distinct dark color and protecting it from minor corrosion.
Key properties:
- High flexibility and ductility
- Moderate strength suitable for tying and binding
- Corrosion resistance for short-term outdoor use
- Smooth surface finish
2. Manufacturing Process of Black Annealed Wire in Iran
Iranian steel mills follow standardized processes to produce high-quality black annealed wire:
- Wire Rod Selection: Low-carbon steel rods are chosen for uniform quality.
- Drawing: Rods are drawn into wire of specific diameters.
- Annealing: Wire is heated in a controlled furnace to improve flexibility.
- Coiling and Packaging: Finished wire is coiled into rolls for distribution.
This process ensures consistency, durability, and compliance with international standards.
3. Features of Iranian Black Annealed Wire
Iranian black annealed wire is recognized for several distinct advantages:
- High Flexibility: Easy to twist, bind, and shape without breaking.
