Zn-Al 85/15 Spray Wire 1.6 mm

Zn-Al 85/15 Alloy for Long-Term Corrosion Protection

The 85/15 zinc-aluminum alloy is widely specified for its dual-mode corrosion protection. The zinc provides active, sacrificial cathodic protection to steel substrates, while the aluminum content forms a stable, passive oxide barrier that slows the consumption rate of the coating. This synergy results in a service life that significantly outperforms pure zinc coatings in many atmospheric and immersion conditions.

This 1.6 mm diameter wire is a common size for high-deposition-rate arc spray systems. It offers a good balance between melt characteristics and feedability, allowing operators to achieve consistent spray patterns and coating quality. The wire is manufactured to tight dimensional tolerances to ensure smooth, uninterrupted feeding through drive rolls and contact tips.

Typical Application Areas

Zn-Al 85/15 coatings are used across a broad range of industries where steel corrosion is a primary concern. The 1.6 mm wire is particularly well-suited for large-area coating jobs and automated or semi-automated spray setups.

• Infrastructure and Bridges: Coating of structural steel, bridge girders, and support columns for long-term atmospheric corrosion protection without the need for frequent maintenance painting.
• Marine and Offshore: Protection of ship decks, hull components, offshore platform structures, and port equipment exposed to salt spray and immersion.
• Industrial Equipment: Coating of water tanks, pipes, ductwork, and processing vessels in chemical plants, water treatment facilities, and power generation.
• Steel Fabrications: Application to welded structures, storage tanks, and transmission poles where hot-dip galvanizing is impractical or as a field-repair coating for damaged galvanized surfaces.

Pack Options and Handling

We understand that production environments vary. This wire is available in standard spool sizes—15 kg, 20 kg, and 25 kg—which are convenient for most arc spray systems. Coil packs are also available for high-volume applications requiring longer uninterrupted run times. Proper storage in a dry environment is recommended to maintain wire surface condition and ensure optimal spray performance.
