Black iron wire, also known as annealed wire or black wire, is a soft iron wire produced by heating and annealing low-carbon steel wire rod. It features a gray-black oxide layer on the surface, offering good flexibility and tensile strength. Typically not galvanized or coated, it is low in cost and widely used for tying, construction binding, craft making, and daily packaging. Common foreign grades include ASTM A510 (USA), BS 1052 (UK), JIS G3532 (Japan), and DIN 177 (Germany). For basic performance parameters, search using the term “black annealed wire specifications” for detailed data.
Shape Classification
Based on wire diameter and forming method, black iron wire can be divided into coil black wire and cut black wire. Coil black wire is supplied in rolls, with common diameters ranging from 0.5 mm to 4.0 mm, suitable for continuous operation. Cut black wire is cut to fixed lengths for specific binding or tying applications. In terms of annealing degree, it can be classified as fully annealed (softer) or partially annealed (slightly higher strength). To compare applications for different diameters, search “black iron wire gauge chart” for wire gauge conversion tables.
Main Applications
On construction sites, black iron wire is often used to tie rebar frameworks. In agriculture, it is used for bundling straw and building simple trellises. In the packaging industry, it is widely used for strapping cartons, pipes, or sheets. Additionally, black iron wire is a basic material for handcrafts, floral arrangements, and wrought iron decorations. Common European grades include C5D and C7D (EN standards), while the US mainly uses wire made from SAE 1006 or SAE 1008. For construction binding applications, search “black wire for rebar tying” to find related products.
Procurement and Trade Suggestions
In international sourcing, attention should be paid to wire diameter (expressed in mm or SWG/BWG gauge numbers), tensile strength, and elongation. Different national standards have varying requirements for diameter tolerance and annealing. For example, BWA 0.9 mm in JIS G3532 corresponds to 21-gauge in ASTM A510. For export comparison, use the search term “black annealed wire equivalent grade” to find standard conversion relationships. To locate overseas suppliers or price information, use “black iron wire suppliers Europe” for reliable resources.
