Zn-Al 85/15 Spray Wire 2.5 mm

Understanding Zn-Al 85/15 Alloy Wire for Thermal Spray

Zn-Al 85/15 is a widely specified pseudo-alloy for anti-corrosion thermal spray coatings. The coating acts as a sacrificial anode, protecting the steel substrate even if the coating is scratched or damaged. The 15% aluminum content enhances the coating's hardness and self-sealing properties compared to pure zinc, making it suitable for more aggressive environments, including pH 5–12 conditions, offshore structures, and bridges.

This 2.5 mm diameter wire is a common standard for high-deposition-rate arc spray systems, offering a good balance between feedability and melt characteristics. It is also compatible with certain high-capacity flame spray guns. The resulting coating provides excellent adhesion to grit-blasted steel surfaces and can be used as a standalone corrosion barrier or as a primer in a duplex coating system with a sealer or topcoat.

Key Features and Benefits

• Proven 85/15 Alloy Chemistry: Offers superior corrosion resistance over pure zinc in industrial and marine atmospheres.
• Sacrificial Protection: Provides cathodic protection to steel, preventing rust at scratches and edges.
• Consistent 2.5 mm Diameter: Ensures smooth, uninterrupted feeding in arc spray systems, minimizing downtime.
• Flexible Pack Options: Available on 15 kg, 20 kg, and 25 kg spools, or in coil packs to suit different production setups.
• Excellent Bond Strength: Adheres reliably to properly prepared (SA 2.5 or near-white metal blast) surfaces.
