Looking for aluminum wire (aluminium wire) for thermal spray metalizing at a competitive price? Airo Shot Blast Equipments is a manufacturer, supplier, and exporter in Jodhpur, India, offering aluminum spray wire for use with compatible arc spray guns and flame spray guns. Our spray-grade wire is used to create bright silver aluminium coatings that help protect steel components against atmospheric corrosion, freshwater exposure, heat, and oxidation in marine, oil refining, chemical processing, and industrial applications. Contact us for current prices, wire specifications, bulk order rates, and a customized quotation for your thermal spray coating requirements.
What Is Aluminum Wire for Thermal Spray?
Aluminum spray wire is drawn aluminium wire made for thermal spray gun. The gun melts it with an electric arc or an oxy-fuel flame, and compressed air sprays the molten metal onto a grit-blasted surface, where it forms a thermally sprayed aluminium (TSA) coating.
Aluminium is a shiny, silver-white metal that quickly forms a thin, tough oxide layer on its surface. That layer is what protects it: it resists many acids and most atmospheric attack, though it is not suited to strongly alkaline conditions.
How Does Aluminum Wire Protect Steel?
- Barrier protection: the dense aluminium layer, with its oxide film, keeps moisture, oxygen and salts away from the steel.
- Galvanic protection: in many atmospheric and freshwater conditions, aluminium acts as a sacrificial anode and protects the steel even at small scratches.
- Heat and oxidation resistance: aluminium withstands high temperatures better than zinc, so it suits hot equipment surfaces.
- Sealed for longer life: a sealer or topcoat fills pores and extends service life.
Used correctly, a thick TSA coating can last for many years with little maintenance.
How to Use Aluminum Wire in an Arc or Flame Spray Gun
- Blast the surface to a clean, rough, near-white finish with a grit blasting machine.
- Choose the gun: an arc spray gun uses two wires. A flame spray gun uses one.
- Match wire to gun: use the diameter your gun is built for, such as 3.15 mm.
- Spray in even passes at the recommended distance.
- Build the thickness your specification requires.
- Seal with a compatible sealer or topcoat.
Key Features & Benefits of Our Aluminum Wire
- Atmospheric and freshwater corrosion protection: A proven coating for many steel structures.
- Heat and oxidation resistance: Higher temperature tolerance than zinc.
- Lightweight: Density of only about 2.7 g/cm³, so the wire is light to handle and ship.
- Bright silver finish: A clean, attractive coating colour.
- Fits arc and flame guns: One wire type for both processes.
- Thick coatings possible: A heavy sprayed layer can replace plating or paint, or sit under paint.
- Low heat to the part: No distortion of the protected component.
- Easy to apply: In the shop or in the field.
- Consistent wire: Smooth, clean feeding for steady spraying.
