Zn-Al 85/15 Spray Wire 3.0 mm

Corrosion Protection with Zn-Al 85/15 Alloy Wire

Zn-Al 85/15 is a widely specified alloy for thermal spray anti-corrosion coatings. The 85% zinc content provides active cathodic protection, sacrificing itself to protect the steel substrate. The 15% aluminum adds a passive barrier layer that slows the consumption of the zinc, extending the service life of the coating compared to pure zinc wire. This makes the 3.0 mm wire a cost-effective choice for applications where long maintenance intervals are critical.

The 3.0 mm diameter is a common standard for high-deposition-rate arc spray guns. It offers a good balance between feedability, melt characteristics, and spray pattern control. The wire is manufactured to consistent chemistry and diameter tolerances, supporting stable spray parameters and uniform coating quality across large surface areas.

Typical Applications for Zn-Al 85/15 Coatings

This wire is used across multiple industries where steel corrosion is a primary concern. Common applications include:

• Bridges and highway infrastructure: Coating structural steel beams, girders, and expansion joints for decades-long corrosion protection without frequent repainting.
• Marine and offshore structures: Protecting ship hulls, decks, offshore platforms, and port equipment from saltwater corrosion and splash zone attack.
• Water and wastewater tanks: Applying internal and external coatings on storage tanks, penstocks, and water gates subject to immersion and humidity.
• Industrial plant and process equipment: Coating ductwork, stacks, heat exchangers, and structural frames in chemical plants, refineries, and power stations.
• Wind turbine towers: Providing a base corrosion-resistant layer on tower sections, both onshore and offshore.

Pack Options and Handling

SPA2Z supplies Zn-Al 85/15 Spray Wire 3.0 mm in multiple pack configurations to suit different job scales and equipment setups. Standard options include 15 kg spools, 20 kg spools, 25 kg spools, and coil packs. Spools are precision-wound for consistent dereeling and tangle-free feeding. Coil packs are available for high-volume, continuous spraying operations where frequent spool changes are impractical.

Store wire in a dry, covered area. While Zn-Al wire is less sensitive to moisture than some ferrous wires, keeping spools in their original packaging until use prevents surface oxidation and maintains optimal feed and spray characteristics.
