Zn-Al 85/15 Spray Wire 4.0 mm

Zn-Al 85/15 Alloy Wire for Industrial Corrosion Protection

Zinc-Aluminum 85/15 alloy wire is widely recognized as a high-performance alternative to pure zinc or pure aluminum coatings. The 85/15 ratio provides active cathodic protection (from the zinc) combined with the passive barrier layer and hardness of aluminum. This synergy results in a coating that resists both atmospheric corrosion and more aggressive industrial or marine exposures.

In thermal spray applications, the wire is melted—either by an electric arc or an oxy-fuel flame—and atomized onto a prepared surface. The resulting coating adheres mechanically to the substrate, forming a dense, protective layer. The 4.0 mm diameter is a common choice for high-deposition-rate arc spray systems, balancing feedability with spray stability.

Typical Applications for Zn-Al 85/15 Coatings

This alloy is used across multiple industries where steel structures require long-term corrosion protection without frequent maintenance. Common applications include:

• Infrastructure and bridges: Coating structural steel to extend maintenance intervals.
• Wind energy: Protecting wind turbine towers, especially in offshore or coastal environments.
• Marine and offshore: Applying corrosion-resistant layers to ship hulls, decks, and offshore platform components.
• Industrial equipment: Rebuilding and protecting worn shafts, rolls, and large fabricated parts.
• Water and wastewater: Coating gates, penstocks, and tanks exposed to immersion or high humidity.

Selection and Handling Tips

To get the best results from Zn-Al 85/15 Spray Wire 4.0 mm, consider the following practical points:

• Process compatibility: Confirm that your arc spray or flame spray system is set up for 4.0 mm wire. Drive rolls, liners, and contact tips must match the diameter.
• Surface preparation: A clean, properly profiled surface (typically achieved by grit blasting) is essential for coating adhesion. The anchor profile should suit the coating thickness you plan to apply.
• Storage: Store spools in a dry, covered area. While Zn-Al wire is less sensitive to moisture than some ferrous wires, keeping packaging sealed until use helps maintain surface condition.
• Pack selection: Choose between 15 kg, 20 kg, or 25 kg spools based on your spray system's spool holder capacity and your production run length. Coil packs may also be available for specific setups.
