Aluminum Wire for Thermal Spray Coating
This 4.8 mm aluminum wire is used as feedstock in electric arc spray and combustion flame spray systems. It produces a dense, well-bonded aluminum coating that acts as a sacrificial barrier against atmospheric and immersion corrosion. Common applications include coating steel bridges, storage tanks, marine components, and industrial ductwork.
The wire is drawn to a consistent 4.8 mm diameter, which feeds reliably through standard drive rolls and spray gun tips. It is packaged on plastic and metal spools in 15 kg, 20 kg, and 25 kg weights. Coil packs are also available for high-volume, continuous-spray operations. The wire surface is clean and free from drawing lubricants that could contaminate the coating.
Selecting the Right Aluminum Spray Wire
Aluminum thermal spray wires are available in different alloy grades, typically commercially pure aluminum (99.0% Al minimum) or aluminum alloys with small additions for specific coating properties. The correct grade depends on your corrosion environment, required coating hardness, and post-spray finishing steps.
When you enquire, share your spray process type (arc or flame), base metal, service environment, and any applicable coating specification. This helps SPA2Z confirm the right wire grade and diameter for your job. We can also advise on spray parameters and surface preparation requirements to help you achieve a sound coating.
