Zn-Al 95/5 Spray Wire 2.5 mm

Understanding Zn-Al 95/5 Alloy Wire for Thermal Spray

Zn-Al 95/5 wire is a widely specified consumable for anti-corrosion thermal spray coatings. The addition of 5% aluminum to the zinc matrix improves the coating's ductility, adhesion, and corrosion resistance, particularly in chloride-rich or industrial atmospheres. The 2.5 mm diameter is a common standard, offering a good balance of feedability and melt rate for most arc spray systems and larger flame spray guns.

This alloy is frequently used as a direct replacement for pure zinc wire in applications where extended service life is required, such as coating bridges, wind turbine towers, marine structures, and water treatment plants. The resulting coating acts as a sacrificial anode, protecting the steel substrate even if the coating is scratched or damaged.

Key Features and Industrial Benefits

• Superior Corrosion Protection: The Zn-Al 95/5 alloy provides significantly better long-term corrosion resistance than pure zinc, especially in salt-laden and industrial atmospheres.
• Excellent Adhesion: The aluminum content promotes a strong metallurgical bond with properly prepared steel surfaces, reducing the risk of delamination.
• Consistent Wire Quality: Manufactured with tight chemistry control and a smooth, uniform surface finish to ensure trouble-free feeding through drive rollers and contact tips.
• Versatile Process Compatibility: Suitable for both electric arc spray and oxy-fuel flame spray systems, offering flexibility for shop-floor and on-site applications.
• Flexible Packaging: Available in multiple spool sizes and coil packs to minimize downtime during changeovers on large projects.

Typical Applications

This Zn-Al 95/5 wire is a primary consumable for industrial corrosion control. Common applications include:

• Steel Bridge Coating: Long-term corrosion protection for structural steel bridges, often as part of a duplex coating system with a paint topcoat.
• Wind Energy: Coating wind turbine towers and foundation sections to withstand harsh outdoor exposure.
• Marine & Offshore: Protecting ship hulls, decks, offshore platform structures, and port equipment from saltwater corrosion.
• Water Infrastructure: Applying corrosion-resistant coatings to penstocks, gates, and water treatment plant steelwork.
• Industrial Fabrications: General anti-corrosion coating for fabricated steel components, tanks, and pipework before installation.

Selection and Handling Guidance

To achieve optimal coating results, ensure the wire is used with properly calibrated spray equipment. The 2.5 mm diameter is a common fit for many standard arc spray guns; however, always confirm your gun's wire feed capability and contact tip size. Store wire spools in a dry, covered environment to prevent surface oxidation before use. For flame spray systems, verify that your torch configuration supports a 2.5 mm wire feed rate for this alloy.
