Specifications of China Black Annealed Wire


China black annealed wire is a type of wire that is widely used in various applications, particularly in construction, agriculture, and manufacturing. This wire, known for its ductility and flexibility, is manufactured through a specific process that includes annealing, which enhances the wire's properties. Understanding the specifications of black annealed wire is essential for consumers and industries looking to utilize it in their projects.


Material Composition and Properties


Black annealed wire is primarily made from low-carbon steel, giving it a high level of malleability. The typical carbon content ranges from 0.1% to 0.3%, allowing the wire to be easily shaped and manipulated without breaking. The annealing process involves heating the wire to a suitable temperature and then allowing it to cool slowly, which relieves internal stresses and further increases its ductility. The result is a smooth, flexible wire that is easy to work with and ideal for various applications.


Common Specifications


The specifications for black annealed wire can vary depending on standard practices and specific applications. However, there are common characteristics that define the wire type


1. Diameter Black annealed wires typically range from 0.2 mm to 6.0 mm in diameter. The diameter chosen often depends on the intended use, with smaller sizes suitable for tying and other intricate tasks, while larger diameters are used for heavier applications.

2. Tensile Strength The tensile strength of black annealed wire generally falls between 300 to 550 MPa. This range ensures that the wire can withstand considerable force without breaking, making it suitable for applications requiring durability and longevity.


3. Surface Finish As the name suggests, black annealed wire has a dark, oily surface finish. This is a result of the annealing process and provides mild corrosion resistance. It also offers a certain level of grip when used for binding or tying purposes.


4. Packaging This wire is typically wound into coils or spools for easy handling and storage. Common coil weights reach up to 1000 kg, depending on the diameter, which can influence transport efficiency and material management for large-scale projects.


Applications


Black annealed wire is extensively used in several fields. In construction, it serves as a reliable binding wire for rebar, holding together structural elements during concrete pouring. In agriculture, it is commonly utilized for fencing, helping to secure livestock and crops affected by external factors. Additionally, manufacturers use it in the production of various wire products, including wire mesh and spring manufacturing.


Conclusion


In summary, China black annealed wire is a versatile and essential material characterized by its low-carbon content, flexibility, and certain tensile strength. The specifications of this wire make it suitable for a variety of applications in construction, agriculture, and manufacturing, ensuring it remains a critical resource across multiple industries. Understanding these specifications allows consumers and businesses to select the appropriate wire for their specific needs, promoting efficiency and effectiveness in their operations.
