Oily Annealed Low Carbon Steel Black Iron Wire

Oily Annealed Black Wire is manufactured using low carbon steel, which undergoes an annealing process to enhance its ductility and reduce its hardness. This annealing process is followed by a coating of protective oil, which serves to prevent rust and corrosion, making it suitable for various industrial applications. The combination of low carbon content and annealing treatment results in a wire that is both flexible and durable, suitable for binding, baling, and tying applications.

Wire Diameter Range

The wire is available in a wide range of diameters, typically from 1.5 mm to 5.5 mm.

• 1.5 mm (0.059 inches) wire
• 2.6 mm (0.102 inches) wire
• 5.5 mm (0.217 inches) wire

Standard Wire Gauge (SWG) Sizes

Oily Annealed Black Wire is categorized by Standard Wire Gauge (SWG) sizes, ranging from SWG 3 to SWG 23:

• SWG 3: Approximately 5.5 mm (0.217 inches) in diameter.
• SWG 10: Approximately 3.25 mm (0.128 inches) in diameter
• SWG 12: Approximately 2.64 mm (0.104 inches) in diameter
• SWG 16: Approximately 1.63 mm (0.064 inches) in diameter
• SWG 23: Approximately 0.64 mm (0.025 inches) in diameter

These sizes allow for precise selection of wire based on the requirements of the task at hand, whether it's for heavy-duty baling or delicate tying.

Tensile Strength

The tensile strength of Oily Annealed Black Wire varies depending on the specific wire diameter and the degree of annealing. Common tensile strength values range from 305 to 700 N/mm², with some variations falling between 260 to 590 N/mm². This range of tensile strength ensures that the wire can withstand various levels of stress without breaking, making it ideal for binding heavy loads or securing materials in place.

Packaging

To accommodate different user needs, Oily Annealed Black Wire is offered in various packaging formats:

• 1 kg small rolls for convenient handling and use in small-scale applications.
• 5 kg reels for moderate usage in workshops or small industrial settings.
• 10 kg coils for medium-duty tasks where a larger quantity of wire is needed.
• 25 kg reels for industrial applications requiring continuous usage.
• 50 kg coils for large-scale industrial operations where bulk wire is necessary.
  

Standards

• The wire is produced in compliance with international standards such as BS 1052 and JIS G3532 SWMA, ensuring consistent quality and performance. These standards specify the mechanical properties of the wire, including its tensile strength and elongation, guaranteeing that the wire meets the requirements of various industrial applications.

Common Applications

• Oily Annealed Black Wire is widely used in several industries due to its versatility. It is particularly well-suited for use in balers, where it is employed as baling wire for securing paper cartons and other materials. The wire’s flexibility and strength make it ideal for tying and binding in construction, agriculture, and general-purpose manufacturing. The oil coating ensures that the wire remains free from rust and corrosion, even in harsh environments.
