200G Black Annealed Wire – lightweight soft iron wire, standard 200g coil weight, via high-temperature sealed annealing. Ultra-soft temper vs. rigid galvanized wire, excellent flexibility for easy manual bending, twisting and knotting without rebound or fracture. Natural black oxide surface from annealing, no coating or polishing, matte black with smooth texture, no burrs. Simplified process, low cost, ideal economical choice for daily light-duty binding. Stable tensile strength, uniform diameter, suits low-load and temporary fixing applications.

The product covers a practical conventional diameter range from 0.63mm to 4.5mm, fully meeting diverse light binding and small-scale fixing demands. It features a stable tensile strength of 350MPa to 500MPa, balancing basic tensile firmness and ultra-soft twisting performance. Adhering to standard 200g single-coil net weight design, each small coil is uniform in size and easy to carry, store and use. With pure soft temper, the wire supports free manual twisting and random bending without springback. It supports flexible packaging forms including conventional coil and spool packing to adapt to different usage and storage scenarios.

This black annealed wire adopts high-quality Q195 low carbon steel wire as the core raw material, which features fine steel texture, low impurity content and excellent ductility foundation. After professional batch high-temperature sealed annealing treatment, the internal molecular stress of the steel wire is fully eliminated, thoroughly improving the rigid and hard characteristics of original drawn steel wire. The surface naturally forms a compact black oxide protective layer during the annealing process, replacing traditional galvanized coating. This special material treatment retains ultra-soft flexibility for manual processing while providing basic anti-oxidation ability for short-term use, perfectly matching the positioning of economical light binding wire.

Focusing on economical and lightweight binding functions, this 200g black annealed wire is widely used in various low-load temporary fixing and bundling scenarios. Its main application fields include light-duty construction steel bar binding and auxiliary fixing, daily waste and sundry bundling sorting, handmade craft tying and shaping, vegetable garden and small orchard temporary branch fixing, as well as commodity small packaging binding and auxiliary fastening, serving as a universal economical binding material for civilian and light industrial use.

The product adopts mature and cost-saving standardized production procedures to ensure stable soft performance: firstly, conduct multi-pass fine steel wire drawing to process the raw steel wire into various target accurate diameters; secondly, carry out batch high-temperature sealed annealing treatment to eliminate internal stress and soften the wire completely; thirdly, form a natural compact black oxide surface without extra polishing or coating treatment; fourthly, complete automatic precision small-coil winding to ensure each roll reaches a standard 200g net weight; finally, finish neat carton bulk packaging for centralized transportation and batch sales.

This black annealed wire has no galvanized anti-rust coating, so it is only suitable for indoor and short-term outdoor use, and long-term exposure to humid and rainy environments should be avoided to prevent surface oxidation and rusting. It is designed for light binding work and cannot bear excessive heavy-load tension to avoid wire breakage. Store the coiled wires in dry and ventilated environments to slow down natural oxidation. Avoid sharp friction during use to prevent surface oxide layer peeling.

Compared with hot-dip and electro-galvanized wires, black annealed wire has no zinc coating, lower cost and softer texture, making it more suitable for manual light binding but lacking long-term outdoor anti-corrosion performance. Different from high-tensile industrial steel wires and rigid nail wires, it features ultra-soft temper with easy twisting, prioritizing usability rather than strength. Compared with large-coil industrial wires, its 200g small-coil design is more portable and user-friendly for daily scattered use, becoming the most cost-effective lightweight binding wire for civilian scenarios.
