(oiled black annealed wire)
Oiled black annealed wire serves as a critical component in construction, agriculture, and manufacturing due to its corrosion resistance and malleability. The annealing process involves heating low-carbon steel wire to 1,000°C followed by gradual cooling, reducing brittleness by 42% compared to non-annealed alternatives. A thin oil coating applied post-production decreases friction during handling while preventing oxidation – field tests show a 67% reduction in rust formation over 18 months in humid environments.
Three key factors differentiate premium oiled black annealed wire
:
Vendor | Price per Ton | Salt Spray Test Hours | Tensile Strength | MOQ |
---|---|---|---|---|
Budget Supplier | $680 | 72h | 320 N/mm² | 15 tons |
Mid-Tier Supplier | $920 | 240h | 410 N/mm² | 8 tons |
Premium Supplier | $1,250 | 500h | 450 N/mm² | 3 tons |
Advanced manufacturers now offer diameter customization from 0.5mm to 4mm with optional enhancements:
A recent infrastructure project in Texas utilized 47 tons of 2.2mm oiled black annealed wire for concrete reinforcement:
Proper storage in climate-controlled warehouses (40-60% RH) maintains oil coating effectiveness. Annual tensile strength tests revealed only 6% degradation over 5 years when stored correctly, versus 21% degradation in uncontrolled environments.
When evaluating cheap oiled black annealed wire against alternatives, life-cycle cost analysis reveals 19-28% savings over 7-year periods. Premium grades justify their higher initial cost through reduced replacement frequency – high quality oiled black annealed wire typically lasts 3.1x longer than basic galvanized wire in mechanical stress applications. For operations requiring maximum reliability, the best oiled black annealed wire combines ISO 9001-certified manufacturing with customized technical support.

A: Oiled black annealed wire is commonly used for binding, construction, and crafts due to its flexibility and rust resistance. The oil coating enhances durability and prevents corrosion. It’s ideal for outdoor or high-moisture environments.
A: Cheap oiled black annealed wire offers basic functionality for light-duty tasks at a lower price. While less durable than premium options, it’s suitable for temporary projects or budget-conscious buyers. Always verify supplier reliability to avoid subpar materials.
A: High quality oiled black annealed wire features uniform thickness, superior tensile strength, and a consistent oil coating for enhanced rust prevention. It’s designed for heavy-duty applications like fencing or bundling industrial materials. This grade ensures long-term performance and minimal breakage.
A: The best oiled black annealed wire combines high carbon content, precise annealing for flexibility, and a durable oil finish. It excels in demanding tasks like agriculture or automotive uses due to its strength and corrosion resistance. Reputable certifications and customer reviews help identify top-tier products.
A: Yes, oiled black annealed wire is suitable for outdoor projects because the oil coating protects against moisture and rust. For prolonged exposure, opt for high-quality variants with thicker coatings. Regular maintenance can further extend its lifespan.
