Premium Black Annealed Wire Suppliers and Factory in China
Our premium Black Annealed Wire, also known as black iron wire or soft annealed wire, is a high-quality carbon steel product engineered for superior flexibility and durability. Produced through a specialized thermal annealing process, this wire undergoes oxygen-free treatment to eliminate internal stresses, resulting in a soft, malleable material that is ideal for intricate binding and fastening applications.
Utilizing Q195 wire rod as the primary raw material, our production involves high-temperature heating (up to 1000°C) followed by controlled cooling. This precise technology refines the grain structure and reduces hardness, significantly enhancing machineability and reducing the tendency for cracking or distortion. Whether you require standard annealed wire or black oiled wire for added protection, our products meet the rigorous demands of modern construction and industrial manufacturing.

Frequently Asked Questions
Black annealed wire is processed through thermal annealing for softness. Black oiled wire undergoes the same process but includes fuel oil injection to provide an additional protective layer against corrosion.
Yes, we can control the degree of hardness and softness by adjusting the annealing temperature and duration based on your specific requirements.
It is primarily used as binding material for rebar, construction tie wire, and in the fabrication of welded mesh, hangers, and fencing.
We use high-quality low carbon steel wire, specifically Q195 and SAE1008, to ensure the best balance of strength and flexibility.
We offer a wide range from BWG 4 to BWG 25, which corresponds to diameters between 0.5mm and 6mm.
Depending on your preference, we package in coils bound with wire, using plastic film, hessian cloth, woven bags, or sturdy cartons.
