Black iron wire is also known as black annealed wire, soft annealed wire and annealed iron wire. Black iron is made of carbon steel wire and obtained by means of thermal annealing. Annealed wire offers excellent flexibility and softness through the process of oxygen free annealing.

Specification

Wire material: carbon steel wire.

Processing: oxygen free annealed process.

Color: plain black.

Treatment: plain oil painted.

Forms available: coil wire, spooled wire, big package wire, U type wire, cut wire.

Sizes: 8 gauge – 38 gauge (0.15 mm – 4.5 mm).

Product Features & Advantages

Black Iron Wire, also known as oil painted black iron wire or black mild steel wire, is a kind of iron wire without any processing. Compared with annealed wire, it is more economical to form coil wire, tie wire, or cut into straight wire. Black iron wire gauge is mainly from 8 G to 38 G (wire diameter from 0.15 mm to 4.5 mm). Another size can accepted as customers' requirements. Black iron wire is the commonly used material in production of woven wire mesh, welded wire mesh and binding wire.

Feature:

Various weights and dimensions.

Excellent flexibility and softness.

Bright and smooth surface.

Anti-corrosion and anti-oxidation.

Long service life.

Annealed wires are much more flexible and easy to work with, which is why they’re commonly used in the recycling and baling industry. The underlying material is always steel and in most cases, the steel is galvanized for added resilience. The process for ferrous materials like steel is different because they react differently to heat.

Black annealed wire is very resilient and doesn't corrode easily, which means it has a better shelf life. You can purchase this wire in bulk and store it in your facility without worry of rust or corrosion.

Black iron wires also have a thin coating of light oil on it to help it pass through the baling machine easily. The oil also protects it from the environment and ensures it doesn’t rust. The wires are simply dipped into special oil until they’re all evenly coated before they’re coiled and packed away. You need to purchase black annealed wires from reliable manufacturers to ensure there’s no fault or weaknesses in them.
