Nickel Alloy 625 Coating Wire for Corrosion Protection
Alloy 625 is widely specified in thermal spraying for its ability to withstand harsh environments. The high nickel content provides a stable, ductile matrix, while chromium delivers oxidation and corrosion resistance. Molybdenum and niobium additions enhance resistance to pitting and crevice corrosion, making this wire a reliable choice for overlays in marine, chemical, and power generation industries.
The 2.0 mm diameter is a common size compatible with many arc spray systems. It offers a good balance between deposition rate and coating quality. The wire is manufactured to tight dimensional tolerances, ensuring consistent feeding and a stable arc. Coatings produced with Alloy 625 wire are typically dense, low in oxides, and exhibit excellent bond strength when applied with proper surface preparation and spray parameters.
Typical Applications for Alloy 625 Spray Wire
- Boiler tube coatings: Protects against sulfidation and chloride corrosion in waste-to-energy and biomass plants.
- Chemical processing equipment: Overlays on vessels, valves, and pump components exposed to acidic or caustic media.
- Marine and offshore: Shafts, seals, and structural components requiring seawater corrosion resistance.
- Dimensional restoration: Rebuilding worn or mismachined parts on high-value industrial components.
Selection and Handling Tips
Store wire spools in a dry, covered area to prevent surface oxidation or contamination before use. Confirm your spray gun's wire drive rolls and contact tips are sized correctly for 2.0 mm wire. For arc spray, typical spray parameters using air or inert gas atomization produce coatings with low porosity and high hardness. Parameter optimization should be performed for each specific application and equipment set.
When ordering, specify the required pack type (spool or coil) and weight. For critical applications, discuss your service conditions with our team so we can confirm the suitability of Alloy 625 and recommend complementary bond coats or sealing treatments if needed.
