How Is Annealed Wire Made?

The wire is used throughout the industry for a wide range of applications, from binding and securing small products together, to providing framing and support for large structures. Manufacturers accommodate all of these applications by manufacturing wire with different shapes, sizes, flexibility, and formulations to fit a variety of requirements and constraints. One of the most common types of wire is annealed wire.

Annealed wire (also known as annealed tied wire) is mild steel wire that has been annealed to increase its ductility and reduce its hardness. These qualities provide greater flexibility without loss of durability, combining to give the wire self-binding and self-locking capabilities. It is available in several variants, each offering unique properties that make it suitable for different use cases.

How is annealed wire made?

Annealing is a heat treatment process that involves heating a material above its recrystallization temperature and then cooling it back to room temperature. The cooling phase for ferrous materials (such as steel) is slower than for non-ferrous materials (such as brass and copper) to prevent the metal from cracking or becoming brittle.

Many metalworking processes increase the hardness of the material, which can make it more difficult to complete subsequent manufacturing operations. Annealing increases the ductility and decreases the hardness of the material, resulting in better formability and machinability. These qualities are critical for many wire applications. If you want to get more information about the best-annealed wire for sale, welcome to contact us today or request a quote.

The manufacturing process for annealed wire is as follows.

Forming the wire from steel (usually mild steel)

Heating the wire to a point above the crystallization point of the base material but below its melting point

Gradually cooling the heated material to below its crystallization point

Oiling to prevent rusting and facilitate mechanical distribution (for black annealed wire)

Types of annealed wire

Annealed tied wire come in many variations, depending on the technology used in their manufacture. The types available include

• Black annealed wire -Black annealed wire is named for its distinctive black color, which comes from the corrosion-resistant surface coating added after the annealing process. It is used in a wide range of industrial and consumer applications, including baling and hand fabrication.

• Bright Wire - Bright annealed wire presents a shiny and smooth finish. It is commonly used for binding and strapping applications.

In addition to black and bright variants, annealed wire is available in a variety of gauges (i.e., wire diameter), forms (e.g., straight-cut, looped, coiled, and U-shaped), and packaging options (e.g., commercial, boxed) wire and tie wire).

• Commercial wire: several large coils of annealed wire wrapped around a holder

• Boxed wire: smaller, tighter coils of annealed wire packaged individually into boxes

• Bundled wire: annealed wire for bundling applications (packaged as commercial wire or box wire)

Why Use It?

For any type of project, you will always try to use the right material to get the job done. Using the wrong product can make the job harder than it really needs to be - and it may even mean you can't get the job done. In the case of wire in particular, choosing the right type is critical because you need the perfect characteristics to avoid problems with the line.
