Copper Thermal Spray Wire 2.3 mm

Copper Coatings for Electrical and Corrosion Protection

Thermally sprayed copper coatings are widely used where a combination of high electrical conductivity and atmospheric corrosion resistance is required. Unlike paint or polymer coatings, a sprayed copper layer provides a true metallic barrier that can also serve as a conductive path. Common industrial uses include:

• Electrical conductivity: Spraying copper onto carbon, ceramic, or polymer components to create conductive surfaces for switchgear, grounding, and lightning protection.
• Corrosion protection: Applying a copper layer to steel structures exposed to industrial or marine environments, often as a primer or functional coating.
• Dimensional restoration: Building up worn copper alloy parts, bearing housings, or sealing surfaces where the base material is copper or a compatible alloy.

Copper wire is generally sprayed using arc spray equipment, where two electrically charged wires are fed into a gun, melted by an arc, and atomized by compressed air. It can also be used in combustion flame spray systems with appropriate wire feed units. The 2.3 mm (approximately 0.090 inch) diameter is a common industrial size compatible with a wide range of standard thermal spray guns.

Selection and Handling Notes

To achieve a high-quality coating, the wire surface must be clean and free from oxidation, drawing lubricants, or moisture. SPA2Z wire is supplied on spools with protective packaging to maintain surface condition during storage and transit. When requesting a quotation, please specify your spray process (arc or flame), gun model, and required pack size so we can confirm compatibility and lead time.
