Metco 51F-NS is a golden-colored, inert gas atomized material. It is a bronze in which aluminum is the main alloying element along with other alloying elements such as iron. The presence of aluminum in these bronzes helps enhance the corrosion resistance of coatings produced from these materials due to the formation of a thin, tenacious surface oxide that acts as a protective layer to the copper-rich alloy. Coatings of these materials are easily machined and excellent finishes are achievable. They have good resistance to fretting and galling at low to moderate temperatures, and excellent resistance to abrasion and cavitation. These coatings are recommended for soft bearing applications. This material is suitable for low temperature applications to produce surfaces where moderate oxidation, wear and cavitation resistance is needed, and when better corrosion resistance than that provided by pure copper materials is needed.""
