Spray wire alloys

The Kanthal® program of spray wire includes the following types of alloys:

  • FeCrAl and FeCrAlY alloys
  • NiCr and NiCrFe alloys
  • NiAl alloys
  • NiFe alloys
  • CuNi alloys


Standard sizes are 1.20, 1.60 and 2.00 mm (0.0472, 0.0693 and 0.0787 inch). Other sizes can be offered on request. The standard delivery form is tight wound on SD 300K spools.

Typical applications

Kanthal® thermal spraying wire is used in a variety of applications, such as:

  • High-temperature oxidation protection used, for example, to resist gases in boiler atmospheres
  • Coatings to resist heat and prevent scaling of conventional low alloy steels
  • Bond coats for improving the adhesion of top coatings
  • Coatings on moulds in the glass industry


Personnel working with thermal spraying should be aware of the hazards connected to the process. They should be familiar with the use of protection equipment for eyes, skin, hearing, respiratory system etc. Personnel should be familiar with safety regulations regarding the complete process, including spraying and the spray equipment used.

This product contains elements, which in certain combinations may be dangerous to your health. We provide Material Safety Data Sheets (MSDS) for this product, which should be read and understood before using the material.

Not following these instructions may be a danger to your health.
