AMPCOLOY 90 is a cast copper with a good combination of electrical and thermal conductivity and resistance to corrosion. It has low room-temperature strength and medium-to-good ductility. These characteristics make it highly suitable for many applications requiring good electrical and thermal conductivity combined with good resistance to corrosion and oxidation. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fatigue. It also includes information on corrosion resistance as well as casting, heat treating, machining, joining, and surface treatment. Filing Code: Cu-413. Producer or source: Ampco Metal Inc..
