Black annealed wire, also known as black high-temperature wire, is a black iron wire drawn from a Q195 wire rod, or a filamentary material made of high-temperature materials such as metal molybdenum and tungsten.

Its name comes from its surface color – black, its surface oxide layer caused this. Choosing black annealed is primarily based on its unique physical and mechanical characteristics, as well as its suitability for different applications. It looks like ordinary black iron wire, but its performance is far superior to ordinary black iron wire. Here are the main reasons why choose black annealed steel wire.

1. It is easier to bend, stretch, and shape

The steel wire is cooled slowly after reaching a specific temperature. This process, called annealing (or softening), produces wire with excellent plasticity and strength. This treatment improves the plasticity and strength of steel wire by reducing its hardness. The annealed steel wire is therefore easier to bend, stretch, and shape. This makes it more advantageous in situations that require bending and twisting.

 

2. It is more stable and less likely to break

Reduced stress concentration: Annealing eliminates the residual stresses and internal defects where the steel is during production and can reduce stress concentration. Due to stress concentration, the annealed steel wire is more stable and less likely to break or fail.

3. It is more corrosion and fatigue-resistant

Annealing can improve wire corrosion resistance and durability. Although annealing does not directly increase the corrosion resistance of steel wires, it can enhance their corrosion resistance by optimizing their organizational structure and chemical makeup. The annealed steel wire is also more durable and has a higher fatigue resistance. This makes it suitable for long-term applications.

4. Its wider range of uses than ordinary steel wire

It has a wide range of uses: It is used in many industries including construction, automotive, electronics, and aerospace. For example, it is used to create scaffolding and steel mesh. In the machinery industry, it is used to manufacture springs, fasteners, and other components. While in the electronics industry, annealed cables can be used for wires and cables.

5. It is high cost-effectiveness

Although the production costs of annealed steel are slightly higher than those of untreated wire, their excellent performance and broad range of applications make them highly cost-effective. Production costs can be minimized by selecting the right annealing materials and processes.

6. It has a longer service life

The annealing process makes it have excellent wear resistance and ductility, able to withstand greater tension, and a dense oxide film will be formed on its surface, which can also resist the invasion of acid and alkali materials, thereby reducing the occurrence of rust. Therefore, its service life is longer than that of ordinary iron wire, reducing the frequency of replacement and reducing costs.

7. Its beautiful surface

The surface of it is very bright, with no uneven color, complete coating, and high aesthetics. For some occasions with higher requirements, such as high temperature and humidity, craft decoration, black annealed wire can fully meet the requirements, while ordinary steel wire has a poor effect.

 

In summary, black annealed wire has become an ideal choice in many industries due to its excellent wear resistance, tensile strength, easy processing, corrosion resistance, flexibility, surface beauty, and long service life, as well as its affordability.  Because annealing changes the physical and chemical properties of the wire， In practical applications, choosing the right annealed-wire materials is important based on specific needs.
