Aluminum Thermal Spray Wire 3.17 mm

Corrosion Protection with Aluminum Thermal Spray Coatings

Thermally sprayed aluminum (TSA) is a proven, long-life solution for protecting iron and steel from rust and chemical attack. Unlike paint, a sprayed aluminum coating provides both barrier protection and sacrificial (galvanic) protection. If the coating is scratched, the aluminum corrodes preferentially, shielding the steel substrate. This makes it a preferred choice for bridges, offshore platforms, marine components, storage tanks, and structural steelwork in aggressive environments.

The 3.17 mm diameter is a standard size that feeds smoothly through most industrial arc spray and flame spray guns. It offers a good balance between deposition rate and coating control, allowing operators to build up uniform layers efficiently.

Key Features and Benefits

• Sacrificial corrosion protection: Protects steel even when the coating is damaged.
• Compatible with arc and flame spray: Works with the two most common thermal spray processes.
• Standard 3.17 mm diameter: Fits widely used spray gun drive rollers and tips.
• Flexible pack sizes: Choose from 15 kg, 20 kg, or 25 kg spools, or coil packs based on job size.
• Dense, well-bonded coatings: Produces low-porosity layers with good adhesion.

Typical Applications

Aluminum thermal spray wire is used across industries where steel durability is critical. Common applications include:

• Marine and offshore: Coating ship hulls, decks, offshore platform legs, and risers.
• Infrastructure: Protecting bridge girders, lamp posts, guardrails, and transmission towers.
• Industrial plant: Coating storage tanks, pipework, ducting, and structural frames in chemical or coastal environments.
• Component manufacturing: Applying aluminum coatings to pump housings, valve bodies, and automotive parts.
• Repair and maintenance: Restoring worn or corroded surfaces on shafts, journals, and bearing housings.

Selection and Handling Tips

• Confirm process compatibility: Arc spray and flame spray systems have different setup requirements. Our team can help you verify that this wire matches your equipment before you order.
• Choose the right pack: For high-volume production, 25 kg spools reduce changeover time. For smaller jobs or field work, 15 kg spools are easier to handle and store.
• Store correctly: Keep wire spools in a dry, covered area. Aluminum wire can oxidize if exposed to moisture, which may affect spray quality.
• Check surface preparation: A clean, properly profiled substrate is essential for coating adhesion. We also supply abrasive media and blasting spares for surface preparation.
