Copper Thermal Spray Wire 4.8 mm

Copper Wire for Arc and Flame Spray Coating

Copper thermal spray wire produces coatings with high electrical and thermal conductivity. Common applications include anti-seize coatings on threaded fasteners, conductive tracks on insulators, and corrosion-resistant layers on steel structures exposed to marine or industrial atmospheres. The 4.8 mm (3/16 inch) diameter is a standard size compatible with many common arc spray systems and larger flame spray guns.

When sprayed, the molten copper particles flatten and rapidly solidify on the prepared substrate, forming a lamellar coating structure. Bond strength and coating density depend on spray parameters, surface preparation, and wire quality. Consistent wire chemistry, cast, and helix help maintain stable feed and a uniform spray pattern.

Pack Options and Handling

SPA2Z offers this copper wire in 15 kg, 20 kg, and 25 kg spools, as well as coil packs for high-volume users. Spools are wound to provide smooth dereeling and consistent wire feed. The wire is protected against surface oxidation during storage and transit. Buyers should specify their required pack type and spool weight when requesting a quotation.
