NiAl 95/5 Thermal Spray Wire
Equivalent to Tafa 75B / PMET 885 / Metco 8400
Nickel-Aluminum Alloy Wire for Thermal Spray Coating Applications
Product Overview
NiAl 95/5 thermal spray wire is a solid wire alloy composed of 95% Nickel and 5% Aluminum, specifically engineered for thermal spray coating processes. It is widely used as a bond coat beneath ceramic topcoats or as a corrosion and oxidation resistant coating on metal substrates.
This wire is fully equivalent to Tafa 75B, PMET 885, and Metco 8400, and is compatible with various spray systems including arc spray and flame spray equipment.
With excellent adhesion properties, high-temperature stability, and resistance to thermal cycling, NiAl 95/5 is commonly applied in aerospace, marine, energy, and heavy industrial sectors.
Chemical Composition (Typical)
| Element | Content (%) |
|---|---|
| Nickel (Ni) | 94.0% – 96.5% |
| Aluminum (Al) | 3.5% – 5.5% |
| Others / Impurities | < 0.5% |
Complies with the standard NiAl 95/5 alloy grade. Equivalent to Tafa 75B, PMET 885, and Metco 8400.
Application Areas
Power & Energy Sector: Bond coat in thermal barrier coating systems for turbines and heat-sensitive components
Aerospace Industry: Protection layer for engine nozzles, exhaust parts, and turbine blades
Marine Applications: Corrosion-resistant coating for pipelines, ship hulls, and offshore platforms
Chemical & Petrochemical Equipment: External coating for pressure vessels, heat exchangers, tanks
Maintenance & Repair: Surface restoration, dimensional rebuild, and wear protection of mechanical parts
Key Features
Strong Adhesion: Excellent bond to steel, aluminum, and other substrates, ideal for use beneath ceramic topcoats
High-Temperature Oxidation Resistance: Suitable for thermal cycling and elevated temperature operations
Corrosion Protection: Forms a protective oxide layer in salt spray, acidic, or chemical exposure environments
Wide Process Compatibility: Supports arc spray and flame spray applications
Thermal & Mechanical Stability: Dense, uniform coatings with good thermal conductivity and mechanical bonding strength
