1. Similarities
Appearance color
Both are black. This is because they may not have been polished during the production process, retaining a relatively original black appearance.
Basic material
Usually low carbon steel is used as the raw material. Low carbon steel has a low carbon content, good toughness and plasticity, and is suitable for processing operations such as drawing into wire.
2. Differences
Processing technology
Black annealed wire
Annealing is a metal heat treatment process that slowly heats the metal to a certain temperature, keeps it for a sufficient time, and then cools it at an appropriate speed. For black annealed wire, annealing can reduce its hardness, improve its toughness and plasticity, and make it easier to carry out further processing, such as bending, winding, etc.
Black iron wire
May not have been annealed or have undergone other special treatments. If it has not been annealed, its hardness is relatively high, and its toughness and plasticity are worse than those of annealed iron wire.
Mechanical properties
Black annealed wire
Due to annealing, it has good flexibility. When subjected to external forces, it is not easy to break and is more suitable for occasions that require a certain degree of deformation ability, such as binding, weaving, etc.
Black iron wire
The hardness is relatively high, and it may show stronger rigidity when subjected to tension or pressure. It may be more suitable in some application scenarios that require a fixed shape and have certain requirements for hardness, such as making simple hooks and other small hardware.
The application scenarios of black iron wire and black annealed wire are mainly different as follows:
Black annealed wire:
Hardware products: used to make some hardware products that need to be bent and formed, such as hangers, hooks, etc. Its good flexibility makes it easy to process into various shapes.
Communication industry: In some scenarios where cables need to be tied, the flexibility of black annealed wire can better adapt to different cable layouts and bending conditions.
Daily handicrafts: Due to easy bending operation, it is often used in the works of some handicraft enthusiasts, such as hand-woven decorations.
Black iron wire:
Construction field: It can be used to bundle building materials such as steel bars. Because of its high hardness, it can provide strong binding force.
Making wire mesh: As the main material, it is used to make some protective wire mesh, such as temporary fences on construction sites.
Crafts production: Used in the production of some iron crafts that require hardness.
