Specifications
Alcro Wire is a ferritic iron-chromium-aluminum alloy (FeCrAl alloy) for use in arc and flame spray systems. The alloy produces dense, well bonding coatings, resistant to high-temperature oxidation and corrosion.
Typical applications for Alcro wire are bond coats in high-temperature coating systems, protective coatings in high-temperature atmospheres containing sulphur or carbon and protective coatings against scaling of conventional low alloy steels.

Machining
Depending of surface finish requirements, the coating may be machined by turning or grinding. For rougher surface, turning using carbide tools, light cuts and efficient cooling to avoid overheating is recommended. Grinding in fine steps using cooling, light pressure and clean wheels gives smoother finish.

Typical coating properties
Summary of results obtained when spraying with a conventional Arc Spray gun, using varying spraying parameters.
| Deposition efficiency (%) | 62-78 |
|---|---|
| Hardness HV (300g) | 165-280 |
| Surface roughness (µm) | 11-16 |
| Porosity (%) | 1-6* |
| Oxides (%) | 5-20* |
*) These results are obtained when using air as spraying gas. Also nitrogen has been used, resulting in lower rates of porosity and oxides.
Safety
Personnel working with thermal spraying should be aware of the hazards connected to the process. They should be familiar with the use of equipment regarding, i.e. eye, skin, hearing and respiratory protection.
