Black annealed wire, also known as soft annealed wire, is a popular choice for the construction industry and household bundling wire. It has good plasticity and ductility, and is softer and smoother than ordinary iron wire.
Annealed wire is a soft iron wire product made from low carbon steel through cold drawing, heating, constant temperature, and heat preservation. It is usually packaged into rolls, spools, or further straightened and cut into cutting wires, U-shaped wires, etc.
Feature:
Soft texture: Annealing treatment changes the internal crystal structure of the iron wire, eliminates internal stress, has good ductility, can be easily bent and coiled, and can meet the processing of complex shapes.
Surface oxidation treatment: A layer of black oxide film is formed on the surface during annealing, which has a unique appearance, provides certain anti-rust and anti-corrosion properties, and prolongs life.
Easy to process: easy to cut, bend, weave, and has good welding performance. Through appropriate welding process, it can be firmly connected with other metals, which is convenient for making various metal products or structural parts.
Low price: Compared with metal wires such as stainless steel wire and copper wire, the production cost is lower, and it has strong competitiveness in cost-sensitive fields.
Strength and toughness: Although soft, it can still withstand certain tension and pressure, and can play a reliable role in scenes with low strength requirements.
Diverse specifications: Commonly used wire numbers range from 5# to 38#, and the corresponding wire diameters range from 0.17mm to 4.5mm, which can meet the needs of various industries.
Wide range of uses: can be used for greenhouse construction in agriculture, crop bundling, filter nets and protective nets in industrial manufacturing, as well as home repairs and temporary bundling and fixation of items in daily life.
Application of different wire diameters
Fine wire: 0.16 mm – 0.6 mm, often used for delicate work, such as bundling and weaving.
Medium wire: 0.6mm-2.0mm, suitable for building bundling, packaging fixing and other scenarios.
Coarse wire: 2.0mm-5.0mm, used for heavy bundling, agricultural fencing and other occasions requiring high strength.
Recommended wire diameter for different purposes
Construction industry: Common wire diameter is 0.7mm-2.0mm, used for tying steel bars, fixing scaffolding, etc.
Agriculture: Common wire diameter is 1.5mm-3.0mm, used for making fences, building greenhouses, etc.
Industrial packaging: Common wire diameter is 0.5mm-1.0mm, used for bundling goods, fixing pallets, etc.
Application scenarios
Construction: During the concrete pouring process, steel bars are fixed by steel bar tying. Tie scaffolding steel pipes to make wire mesh, building enclosures, protective nets, etc.
Agriculture: Fix greenhouse frames and covering materials. Build livestock fences and divide fields. Tie crops to prevent them from falling over.
Industrial packaging: bundling goods in logistics transportation, fixing goods on pallets, making packaging tapes, etc.
Handicrafts: making woven crafts, such as wire flowers and animal sculptures. Home DIY, such as making bookshelves, hooks, hangers, etc.
Others: gardening, fixing plants, building flower stands, etc.; making fishing nets, repairing fishing gear, etc.; mine support, fixing equipment, etc.
