Alloy 625 Spray Wire 3.0 mm

Why Alloy 625 for Thermal Spray Coatings

Alloy 625 (often referred to by the trade name Inconel 625) is widely specified for thermal spray coatings because of its exceptional resistance to corrosion, oxidation, and a broad range of aggressive media. The wire chemistry—primarily nickel with significant chromium and molybdenum additions—provides reliable protection in seawater, chemical processing, and elevated-temperature service environments where lesser alloys would degrade quickly.

Common coating purposes include:

• Corrosion protection: Shielding boiler tubes, heat exchangers, and process vessels from wet corrosion, acid attack, and chloride-induced pitting.
• Rebuild and dimensional restoration: Salvaging worn shafts, bearing journals, and pump components that require a corrosion-resistant build-up layer.
• High-temperature oxidation resistance: Protecting components exposed to cyclic heating and aggressive flue gases up to approximately 1000 °C (needs confirmation for your specific operating conditions).

Wire Diameter and Spray Process Compatibility

The 3.0 mm (1/8 inch) diameter is a common size for both electric arc spray and combustion flame spray systems. Arc spray typically offers higher deposition rates and is preferred for large-area corrosion protection and rebuild work. Flame spray may be selected when a finer as-sprayed finish or lower capital equipment cost is required.

Process fit depends on your spray gun model, wire feed rollers, and power source. SPA2Z recommends confirming the wire diameter tolerance and surface finish with your equipment manual before ordering. If you are unsure, our team can help cross-check your gun specifications against this wire.

Pack Options and Handling

Alloy 625 Spray Wire 3.0 mm is available in the following pack configurations to match different production volumes and feeder setups:

• 15 kg spool
• 20 kg spool
• 25 kg spool
• Coil pack (weight on enquiry)

Spools are precision-wound to ensure consistent payoff and minimal tangling during continuous spraying. Coil packs are available for high-volume users with suitable dereeling equipment. Store wire in a dry, covered area to prevent surface contamination that could affect arc stability or coating quality.
