Zinc Aluminum Alloy Wire

Zinc aluminum alloy wire is a new type of anti-corrosion material. It has the characteristics of strong adhesion, good wear resistance, and corrosion resistance. Compared with zinc wire and pure aluminum wire, it has stronger performance. Wanzhi Steel has many years of experience in the production of zinc-aluminium wire. In addition, we have a complete production line and production management system to ensure the quality of zinc aluminum alloy wire. If you are looking for this kind of metal wire for your project, you can contact us for more details.

Features

• Excellent corrosion resistance: Combining the advantages of zinc and aluminum, it can provide long-term protection in harsh environments. Especially in marine climates, high humidity or corrosive media, its corrosion resistance is better than pure zinc or pure aluminum materials, and its service life is 2-3 times that of galvanized wire.
• Good mechanical properties: It has high strength and ductility, and can withstand large mechanical stress without breaking easily. Its elongation at break is high, which is suitable for application scenarios that require bending or winding, such as cable sheaths, braided nets, etc.

High Quality Steel Wire

Finished Product

• Low melting point and easy processing: The melting point of zinc-aluminum alloy is relatively low, which is convenient for processing into wires of different diameters and shapes (round wire, flat wire) through casting, extrusion, cold drawing, rolling, and other processes. Meet the diverse needs of plating, weaving, welding, etc.
• High and low temperature resistance: The oxidation resistance at 200℃ is better than that of pure zinc, and the aluminum oxide film can inhibit the volatilization of zinc and maintain the stability of the material; it still maintains toughness in low temperature environments below -40℃, and is not easy to break brittlely, which is suitable for application in severe cold areas.
• Excellent coating performance: Common thermal spraying or electroplating processes can form a dense protective layer on the surface of the substrate. The coating has good adhesion and uniformity, which can prevent corrosion of the substrate. It can also be further passivated and painted.
• High cost-effectiveness: Compared with pure zinc or pure aluminum materials, zinc-aluminum alloy wire can reduce material costs while maintaining excellent performance. Its long life and low maintenance requirements further improve the overall cost-effectiveness and are suitable for large-scale applications.
• Good electrical and thermal conductivity: Suitable for application scenarios that require electrical connections or heat dissipation, such as electronic components, radiators, etc.
• Customizability: The zinc and aluminum composition and processing technology of zinc-aluminum alloy wire can be adjusted according to needs to meet the performance, size, and shape requirements of different customers.

Production Process

Production steps

1. Alloy Preparation

Firstly, aluminum ingots are placed in the crucible. Next, after the aluminum ingot is melted, add the zinc ingot in a certain proportion. Wait until both are all melted and then stir well. Finally, add a degassing agent for degassing refining for 5~10 minutes.

2. Coarse Embryo Preparation

The coarse embryo preparation is carried out by a shock chain type horizontal continuous casting equipment, which uses the tension and relaxation of the drive chain to realize the stop-pull mechanism and finally the horizontal continuous casting. The process is to add the alloy liquid to the continuous casting furnace and maintain it at the specified level and temperature. Then the ingot drawing system is activated to draw out the rough embryo. After passing the inspection, the rough ingot will go to the next process.

3. Drawing Process

Drawing is the final process of transforming zinc aluminum alloy into a specific size. First of all, the coarse embryo is added to the holding furnace for preheating. After a period of holding, they are drawn. Depending on the wire diameter, the number of pulls varies. For example, a wire with a finer wire diameter will be drawn more often.

Quality inspection and packaging

1. Quality inspection

• Composition analysis: Use a spectrometer to detect the content of zinc, aluminum and other elements to ensure that they meet the standards (such as Zn-5%Al or Zn-10%Al).
• Mechanical properties: Test tensile strength, elongation, etc. to ensure that the wire meets the requirements of use.
• Surface quality: Check for defects such as cracks, burrs, oxide scale, etc. to ensure smoothness and uniformity.
• Diameter tolerance: Use a micrometer or laser diameter gauge to ensure that the wire diameter meets the specifications (such as ±0.02mm).
• Corrosion resistance: The Salt spray test evaluates the corrosion resistance of the coating or alloy.

2. Packaging method

• Winding method: Use an I-shaped wheel or a spool to wind neatly to avoid twisting and deformation.
• Rust prevention: Apply anti-rust oil or vacuum packaging to prevent oxidation.
• Outer packaging: The inner layer is wrapped with moisture-proof paper or PE film, and the outer layer is reinforced with wooden boxes, iron barrels, or woven bags, and labels are affixed to indicate material, specifications, batches, and other information.

Precautions When Transporting and Storing Zinc Aluminum Alloy Wire

The correct way of transportation will not damage the wire. Proper storage methods can make the wire last longer. Next, Wanzhi Steel will show you how to transport and store metal wire.

1. Before shipping, make sure that the wire is packed tightly to prevent it from being damaged due to bumping in transit.
2. It is forbidden to ship steel wire in packages and conveyances with acids, alkalis, salts, etc. that corrode zinc.
3. For storage, it should be placed in a dry, ventilated warehouse free of corrosive substances.
4. When stored outdoors, do not let it get wet by rain.

5. Avoid heavy pressure, store flat or vertically to prevent deformation of the wire or surface damage.

6. Regular inspection. During long-term storage, check the surface condition regularly and re-treat with rust prevention if necessary.
