Zn-Al 95/5 Spray Wire 4.0 mm

Why Zn-Al 95/5 alloy for thermal spray coatings

Zn-Al 95/5 wire is widely specified where galvanic protection from zinc is required, but with improved coating life and reduced porosity compared to pure zinc wire. The 5% aluminum addition refines the coating microstructure, enhances adhesion, and provides better resistance in chloride-rich or marine-industrial environments.

Typical applications include coating of bridges, offshore platforms, ship hulls, wind towers, transmission poles, LPG cylinders, and structural steelwork. The coating serves as a sacrificial anode, protecting the steel substrate even if the coating is scratched or damaged in service.

4.0 mm diameter — production throughput and compatibility

The 4.0 mm diameter is a standard size for high-deposition arc spray systems and larger flame spray setups. It offers a practical balance between melt rate and feed stability. Consistent wire diameter and cast/helix control are essential for uninterrupted spraying — SPA2Z verifies dimensional tolerance and spool winding quality before dispatch.

If your system requires a different diameter, or if you are unsure which diameter matches your gun and drive rollers, mention your spray equipment model during enquiry. SPA2Z can help confirm compatibility and suggest alternative diameters from the available range.

Pack options and handling

Standard pack options for Zn-Al 95/5 4.0 mm wire include:

• 15 kg spool
• 20 kg spool
• 25 kg spool
• Coil pack (weight confirmed on enquiry)

Spools are wound for consistent dereeling with minimal tangling. Coil packs suit high-volume users with appropriate dereeling equipment. Specify your preferred pack type and quantity when requesting a quotation.
