Annealed Wire: The Ultimate in Versatility and Formability for Demanding Applications

Annealed wire, often referred to as "soft" wire, is a fundamental yet highly engineered product where controlled flexibility and ductility are paramount. Unlike its spring-tempered or high-tensile counterparts, annealed wire undergoes a precise heat treatment process that alters its microstructure, resulting in a material that is exceptionally malleable, easy to shape, and forgiving to work with. At here, we produce annealed wire to exacting standards, ensuring consistent performance for a vast array of industrial, construction, and manufacturing needs.

The Annealing Process: Engineering Softness

Annealing is a controlled thermal process where low-carbon or mild steel wire is heated to a specific temperature and then cooled slowly. This process:

• Relieves Internal Stresses: Eliminates brittleness and hardness induced by previous cold drawing or working.

• Promotes Recrystallization: Refines the grain structure, restoring ductility.

• Enhances Formability: The wire becomes pliable and can be bent, twisted, or formed repeatedly without fracturing or exhibiting significant spring-back.

The result is a wire that offers an optimal balance of adequate tensile strength for holding tasks and superior elongation for ease of use.

Key Material Properties and Advantages

• High Ductility & Elongation: Can be stretched and deformed significantly without breaking, making it ideal for manual twisting, tying, and weaving.

• Excellent Formability: Easily shaped by hand or with simple tools, conforming perfectly to irregular surfaces.

• Uniform Softness: Consistent annealing ensures the entire coil or spool has the same workable characteristics.

• Good Weldability: Readily accepts spot welding or other joining methods in fabrication.

• Surface Finish: Typically available in a clean, black (uncoated) oxide finish from the annealing furnace, or with subsequent coatings like galvanization.

Standard Specifications and Sizes

Our annealed wire is manufactured to meet recognized industry standards (e.g., ASTM, ISO) and is available in a comprehensive range of dimensions and packages.

Medium (12-15 Ga)	2.8 mm - 1.8 mm	Coils (5kg to 25kg)	Most common range. Rebar tying, fencing, mesh weaving, general fabrication.
Heavy (6-11 Ga)	5.0 mm - 3.0 mm	Heavy Coils	Heavy-duty bundling, structural armature, agricultural uses, trailer mesh.
Extra Heavy (2-5 Ga)	6.0 mm+	Custom Coils/Pallets	Industrial strapping, vineyard posts, large-scale sculpture armature.

Tensile Strength: Typically ranges from 300 MPa to 500 MPa, prioritizing bendability over ultimate strength.Coating Options: Available in Black Annealed (standard), Galvanized Annealed (for corrosion resistance), and Bright Annealed (clean, scale-free surface).

Critical Applications Across Industries

1. Construction & Masonry:

   • Rebar Tying: The premier choice for manually tying reinforcing steel bars (rebar) in concrete forms due to its easy twisting and breaking by hand.

   • Brick/Block Ties: Embedded in mortar joints to provide wall ties for cavity wall construction.

2. Manufacturing & Fabrication:

   • Wire Forming: Used to create custom hooks, clips, handles, and brackets where complex shapes are needed without specialized machinery.

   • Baling & Bundling: Securing scrap metal, textiles, or other materials for handling and recycling.

   • Weldment Core: Serves as the base material for manufacturing welded wire mesh and grids.

3. Agriculture & Horticulture:

   • Vineyard & Plant Tying: Gently secures plants to stakes without cutting into growing stems.

   • Fencing Repair: Easy to work with for mending wire fences and grids.

   • Baling Twine: A core component in the production of baler twine for hay and straw.

4. Arts, Crafts & Specialty Uses:

   • Sculpture Armature: Provides the flexible, pliable "skeleton" for clay and plaster sculptures.

   • Jewelry Making: Used as a base for wrapped jewelry designs.

   • General Purpose Tying & Fastening: An all-purpose solution in workshops, warehouses, and gardens.
