3. Black Iron Wire Manufacturing Process (with Visual Flow)
Black iron wire is produced through a meticulous series of metallurgical processes, ensuring optimal mechanical performance and surface quality.
- Wire Rod Selection
High-grade low-carbon steel (Q195/Q235) with certified chemical composition, accredited by ISO and AISI.
- Drawing
Progressive cold drawing reduces rod diameter; achieves uniformity & optimal mechanical strength.
- Annealing (Key Step)
Wire heated in oxygen-lean furnace (~700℃) and cooled, increasing ductility and surface oxidation, forming a black oxide film – key for flexibility.
- Surface Treatment
Optional light oiling or phosphate passivation to enhance storage life.
- Spooling/Coiling
Wires are wound into coils or cut into straight wire for shipping and secondary processing.
- Inspection & Quality Control
Rigorous testing (tensile, elongation, surface) in accordance with ISO 9001 and ANSI/ASTM standards before packing.
Process flow: Wire Rod → Drawing → Annealing (Key) → Surface Treatment → Coiling → Inspection.

9. Black Iron Wire: Expert FAQ
Q1: What is the material grade of black iron wire, and why is Q195/Q235 preferred?
A1: Black iron wire typically uses low-carbon steel grades Q195 or Q235, which provide a balance of tensile strength (350–550 N/mm²) and ductility, ensuring both flexibility and robustness for diverse usage.
Q2: What industry standards govern black iron wire production?
A2: Industry standards include ASTM A510 (General Requirements for Wire Rods), ISO 9001 (Quality Management), and ANSI specifications, guaranteeing mechanical and dimensional consistency.
Q3: How does black annealed iron wire differ from galvanized or plain iron wire?
A3: Black annealed wire is fully softened by thermal annealing, offering higher elongation and flexibility. Galvanized wire is zinc-coated for extreme anti-corrosion uses; annealed wire is more ductile, suited for tying/binding.
Q4: What about wire diameter tolerances and surface finish?
A4: Standard tolerance is ±0.05mm. Advanced surface treatment (oil/coating) resists rust and flaking; Tikemetal ensures a uniform black oxide film via controlled annealing.
Q5: What coil sizes and packaging are available?
A5: Standard coils are 25kg, 50kg, 100kg, and customizable. Each coil is shrink-wrapped, palletized, or as spooled straight-cut wire according to customer needs.
Q6: What is the installation standard for construction use?
A6: Installation practices adhere to GB50010 (China), ACI 318 (USA), and EN 1992 (Europe) for rebar tying/binding, ensuring structural integrity and safety.
Q7: How is product traceability and quality control ensured?
A7: Each black iron wire is batch-coded, along with mill test reports and certificates traceable to raw materials; third-party SGS/BV inspection available.
