Zn-Al 85/15 Spray Wire 1.2 mm

Understanding Zn-Al 85/15 Alloy for Thermal Spray

Zn-Al 85/15 is a widely adopted pseudo-alloy in the thermal spray industry. The 85% zinc content provides active cathodic protection, sacrificing itself to protect the steel substrate even if the coating is scratched or damaged. The 15% aluminum content enhances the coating's hardness and forms a stable oxide layer, improving resistance to atmospheric corrosion and extending the coating's lifespan compared to pure zinc wires. This combination makes it a cost-effective alternative to pure aluminum or pure zinc in many applications.

Spray Process Compatibility

The 1.2 mm diameter is a standard size compatible with most common arc spray and flame spray systems. In the electric arc spray process, two wires are fed into the gun, and an electric arc melts the tips. Compressed air atomizes the molten metal and propels it onto the prepared surface. In the flame spray process, the wire is fed through a flame that melts it, with compressed air providing atomization. The specific process fit should always be confirmed based on your equipment manufacturer's recommendations, which our team can assist with during enquiry.

Pack Options for Production Efficiency

SPA2Z offers this wire in several pack sizes to minimize downtime and match your project scale. Standard options include 15 kg spools, 20 kg spools, and 25 kg spools, which are precision-wound for consistent, snag-free feeding. Coil packs are also available for high-volume applications requiring longer uninterrupted spray times. Selecting the right pack size helps optimize material handling and reduces changeover frequency on the shop floor.
