Product Description 1.6mm 3.17mm Tafa Alcro Wire Cr23al51. IndroductionAlcro 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.2.Chemical composition C %Si %Mn %Cr %Al %Fe %Nominal composition Bal.Min---20.55.3 Max0.080.70.423.56.3 MachiningDepending 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.Mechanical propertiesWire sizeYield strengthTensile strengthElongation?Rp0.2RmAmmMPaMPa%1.68309305Physical propertiesDensity g/cm37.10Electrical resistivity at 20°C Ω mm2/m1.45Melting point1500 °CMagnetic PropertiesThe material is magnetic up to approximately 600 °C (the Curie point).Dimension tolerance mm+ 0/-0.05 Young's ModulusTemperature °C20GPa220Typical coating propertiesSummary of results obtained when spraying with a conventional Arc Spray gun, using varying spraying parameters.Deposition efficiency (%)62-78Hardness HV (300g)165-280Surface roughness (μm)11-16Porosity (%)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.
