Copper Thermal Spray Wire 3.17 mm

About Copper Thermal Spray Wire 3.17 mm

Copper thermal spray wire is a primary feedstock for electric arc spray (twin-wire arc spray) and, in some cases, combustion flame spray processes. The 3.17 mm diameter is a standard size compatible with most commercial arc spray guns and drive systems. When sprayed, the wire atomizes into fine molten droplets that flatten and solidify on the prepared substrate, building up a functional copper coating layer by layer.

Typical applications demand the inherent properties of copper: high electrical conductivity, excellent thermal conductivity, and natural corrosion resistance in non-acidic environments. Common uses include spraying conductive paths onto non-conductive surfaces, applying anti-seize or anti-galling coatings to threaded fasteners, and rebuilding worn copper alloy components back to dimensional tolerance. The coating also serves as a bond coat or a decorative architectural finish.

Because copper is a relatively soft, ductile metal, the as-sprayed coating is machinable. This allows workshops to spray slightly oversize and then finish-machine the part to the exact required dimensions. The wire is manufactured to consistent chemistry and diameter tolerance, ensuring stable arc voltage, steady feed rates, and repeatable coating quality across production runs.

Pack Options and Handling

This wire is available on plastic or metal spools in 15 kg, 20 kg, and 25 kg weights. Coil packs can also be arranged for specific dispensing systems. Spools are individually sealed to protect the wire surface from moisture and workshop contamination before use. We recommend storing spools in a dry, covered area and handling them with clean gloves to prevent surface oils from transferring to the wire, which can cause arc instability or coating porosity.
