Product Description

FeNi52 is an austenitic iron-nickel alloy (FeNi alloy) alloy for use in arc and flame spray systems. The alloy has low resistivity and a high-temperature coefficient of resistance.

Typical applications for SW 782 are mould coatings in the glass industry or build-up coatings for dimensional restoration.

Nominal composition	52.0	Bal.

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 (%)	65-78
Hardness HV (300g)	130-215
Surface roughness (μm)	7-13
Porosity (%)	1-5*
Oxides (%)	15-22*

*) These results are obtained when using air as spraying gas. Also nitrogen has been used, resulting in lower rates of porosity and oxides.
