China factory black annealed wire diameter 1.5mm for tie wire

The core advantage of black annealed wire lies in the excellent flexibility and plasticity provided by the annealing process, which makes it difficult to break after bending and has good ductility, making it easy for subsequent processing operations such as winding, bundling, and weaving; The surface oxide film can also have a certain preliminary anti rust effect, and further anti rust treatments such as galvanizing and painting can be carried out according to the needs. This product has various specifications (wire diameter usually between 0.5mm-6.0mm) and is widely used. It is commonly used for binding steel bars and fixing scaffolding in the construction field, as well as serving as a substrate for woven nets (such as breeding nets and protective nets). It can also be processed into daily and industrial accessories such as hangers, hooks, and handicraft supports. It is a cost-effective basic metal wire.

    Soft black Annealed iron wire’s key specification is wire diameter, with standard ranges of 0.5 mm–6.0 mm (custom options: 0.3 mm–12.0 mm) and tight tolerance (±0.02 mm–±0.05 mm) for consistency.

    • Material: Low-carbon steel (0.08%–0.25% carbon), e.g., SAE 1008/1010 or Q195/Q235—critical for post-annealing softness.
    • Mechanical properties: Tensile strength (300 MPa–500 MPa, lower than hard-drawn wire for better flexibility) and elongation rate (15%–30%, higher than hard-drawn wire for stretchability without breaking).
    • Packaging: Tailored to use: large coils (25 kg–500 kg, for industry), small spools (0.5 kg–25 kg, for DIY/small-scale use), or cut bundles (0.5 m–6 m, for on-site construction).
    • Surface treatment: Uncoated (mild short-term rust resistance), galvanized (hot-dip/electro-galvanized, for corrosion protection), or PVC-coated (colored, for aesthetics + extra protection).

    Production Application

    galvanized WIRE black annealed wire

    1. Daily and handmade scenes
    Handmade: Used as a skeleton material for woven jewelry, it can be used for decoration and shaping, and is easy to bend and shape.
    Household use: bundling miscellaneous items, fixing green plant supports, temporarily reinforcing simple furniture, easy to operate.
    In the agricultural field, short-term bundling of crop straw, vines, or packaging of small batches of fruits and vegetables is cost-effective.
    2. Architecture and Decoration Scene
    Construction: Binding steel reinforcement nodes, fixing scaffolding protective nets and small templates to enhance safety.
    Decoration project: fix wall insulation cotton and steel wire mesh to tightly bond with cement mortar; Auxiliary ceiling positioning.
    Installation adaptation: Temporarily fix the frame during door and window installation, wrap and protect the pipeline interface to prevent collision.
    3. Industrial and Production Scenarios
    Workpiece processing: Bundle small metal workpieces, adapt to high temperature environments during heat treatment, and ensure stable positioning.
    Hardware production: Produce simple basketball net frames (such as basketball net frames) as connecting and positioning components for hardware accessories.
    Packaging logistics: bundling and fixing parts packaging, reinforcing lightweight cargo pallets to prevent shaking and damage during transportation.
