Black Iron Wire at Qunkun Metal

Features:

Black iron wire, also known as black annealed wire, is a type of iron wire that has been heat-treated to achieve a black color and certain mechanical properties. It has the following features:

Unique Color: Black iron wire has a black color that is more aesthetically pleasing than traditional iron wire. This color can make it suitable for various decorative and architectural applications.

Mechanical Properties: Black iron wire has been heat-treated to achieve specific mechanical properties, such as tensile strength and ductility. This treatment improves the wire's resistance to stretching, bending, and twisting without breaking.

Durability: Black iron wire is more durable than regular iron wire due to its heat treatment. It can withstand harsh environments, such as outdoor weathering, without significant rusting or corrosion.

Versatility: Black iron wire can be used for various applications, including reinforcing concrete structures, creating decorative fences and gates, and more. Its black color provides an elegant and modern touch that is suitable for both residential and commercial projects.

Cost: Black iron wire may be more expensive than regular iron wire due to the additional processing involved in heat treatment and coloration. However, its durability and aesthetic appeal can make it a cost-effective choice in the long run.

In summary, black iron wire offers a unique black color, improved mechanical properties, durability, versatility, and can be a cost-effective choice for various applications.

Black annealed wire is made of low-carbon steel cold drawn, heated, constant temperature, insulation and other processing into a soft wire products. The use of wire is different, the composition is different, it contains the ingredients are: iron, cobalt, nickel, copper, carbon, zinc, and other elements. The hot metal blanks rolled into 6.5mm thick steel bar is the wire rod, and then into the drawing device into a different diameter of the line, and gradually reduce the diameter of the drawing plate, cooling, annealing, coating and other processing Craft made of a variety of different specifications of the wire.
