Alloy 718 Spray Wire 3.0 mm

Understanding Alloy 718 Thermal Spray Wire

Alloy 718 (often referred to by the trademark Inconel 718) is a nickel-chromium alloy with additions of molybdenum, niobium, and titanium. In thermal spray form, it is used to deposit dense, well-bonded coatings that protect base materials from wear, high-temperature oxidation, and corrosive attack. The 3.0 mm diameter is a common size for high-deposition-rate arc spray systems and heavy-duty flame spray torches.

Typical coating applications include dimensional restoration of worn shafts and bearing journals, repair of gas turbine and aerospace components, and protection of industrial parts exposed to heat and aggressive chemical environments. The alloy's ability to retain mechanical properties up to approximately 700°C (1300°F) makes it a strategic choice for hot-section component maintenance.

Key Features and Industrial Benefits

• High-temperature strength: Maintains hardness and structural integrity in elevated-temperature service, reducing coating degradation.
• Oxidation and corrosion resistance: The nickel-chromium chemistry forms a protective oxide layer, resisting scaling and chemical attack.
• Good sprayability: Consistent wire chemistry and diameter tolerance support stable feeding and uniform melting in arc and flame spray systems.
• Versatile pack options: Supplied on 15 kg, 20 kg, or 25 kg spools, or in coil packs to suit different production setups and consumption rates.

Application Guidance for Buyers

When selecting Alloy 718 spray wire, consider the base material, service temperature, and the specific degradation mechanism (wear, corrosion, or oxidation). This alloy is frequently specified for:

• Salvage and dimensional build-up of nickel-alloy and stainless steel components.
• Protective coatings on furnace parts, heat exchangers, and chemical processing equipment.
• Bond coats or intermediate layers in multi-layer thermal spray systems.

Process parameters such as spray distance, current/voltage settings, and atomizing gas pressure should be optimized for the 3.0 mm diameter. SPA2Z recommends confirming process fit with your equipment manufacturer or our technical team before finalizing your order.
