The specifications of zinc aluminum wire can be described from the following aspects:

Diameter:
- The diameter of zinc aluminum wire generally ranges from 0.3 millimeters to 15 millimeters. Common specifications include 0.5mm, 0.8mm, 1.2mm, 1.6mm, 2.0mm, 3.0mm, 4.0mm, 5.0mm, etc. Different diameters are suitable for different application scenarios. For example, thinner zinc aluminum wires may be used for the anti-corrosion treatment or welding of small parts that require high material precision, while thicker ones are used for the surface anti-corrosion spraying of large structures.
Composition ratio:
- Different zinc aluminum wires have different ratios of zinc to aluminum. Common ratios are ZnAl85/15 (about 85% zinc and 15% aluminum), ZnAl95/05 (about 95% zinc and 5% aluminum), ZnAl98/02 (about 98% zinc and 2% aluminum), etc. The different composition ratios affect the properties of the zinc aluminum wire, such as corrosion resistance, wear resistance, and melting point.
Tolerance:
- For different diameter ranges of zinc aluminum wire, the tolerance requirements are also different. Generally, the tolerance requirement is relatively higher for thinner wires. For example, for zinc aluminum wires with a diameter of 0.3mm to 1.0mm, the tolerance may be within ±0.03mm; for those with a diameter of 1.0mm to 2.0mm, the tolerance may be around ±0.05mm; and for wires with a diameter of 2.0mm or above, the tolerance may be ±0.07mm or more.
Length:
- The length of zinc aluminum wire is usually customized according to customer needs. Common packaging forms include coiled on a spool, bundled, and packed in a barrel. Coiled zinc aluminum wire is generally shorter in length and suitable for the continuous use of some automated equipment; bundled wire is relatively longer in length and convenient for manual operation; and the length of wire in a barrel is determined by the size of the barrel and is generally used for large-scale procurement and storage.
Surface quality:
- High-quality zinc aluminum wire should have a smooth surface, without corrosion products, burrs, cracks, or shrinkage cavities. A smooth surface is beneficial for better adhesion and corrosion resistance, as well as for ensuring the quality of subsequent processing and application.
Mechanical properties:
- Tensile strength: The tensile strength of zinc aluminum wire is an important mechanical property index, which generally should meet certain standards. For example, the tensile strength may be ≥200MPa.
- Elongation: The elongation of the wire reflects its ductility. Commonly, the elongation of zinc aluminum wire is ≥40%.
Packaging:
- Packaging specifications also vary. Common packaging includes 15-40kg per bundle, 5-20kg per spool, and 50-250kg per barrel. Appropriate packaging is selected according to the diameter, length, application scenario, and requirements for transportation and storage.

The use scenarios of zinc-aluminum wire are as follows:

1. Anti-corrosion applications

Infrastructure protection: In bridges, highways, and railway structures, zinc-aluminum wire can be used for anti-corrosion coatings. For example, it can be sprayed on the steel surfaces of bridges to prevent rust and corrosion caused by exposure to the elements.
Marine environments: In the marine industry, it is used on ship hulls, offshore platforms, and other marine structures to resist the corrosive effects of saltwater.
Industrial facilities: In factories and industrial plants, it can protect metal equipment and structures from corrosion caused by chemicals and moisture.

2. Wending and brazing

Metal fabrication: Zinc-aluminum wire is used in welding and brazing processes to join different metal parts. It provides good bonding strength and is suitable for a variety of metals.
Automotive industry: In the production of automobiles, it can be used for welding and brazing of components such as exhaust systems and body panels.

3. Electrical applications

Electrical conductors: In some low-voltage electrical applications, zinc-aluminum wire can be used as a conductor due to its good electrical conductivity.
Grounding systems: It is used in grounding systems to provide a reliable path for electrical currents to flow into the ground.

4. Decorative and artistic applications

Jewelry making: Zinc-aluminum wire can be used to create unique jewelry pieces due to its malleability and decorative appearance.
Art installations: Artists may use it in sculptures and installations for its aesthetic qualities and durability.

5. Filters and meshes

Industrial filters: Zinc-aluminum wire meshes are used in industrial filters to separate solids from liquids or gases.
Screens and grilles: In architecture and interior design, it can be used for making screens and grilles for ventilation and decoration
