AMPCOLOY 62 is a cast copper-base alloy known as low-tensile manganese bronze. Despite the fact that it is at the low-strength end of the manganese bronzes, it has a tensile strength about 20,000 psi greater than that of the corresponding copper-zinc alloys; therefore, it is often classified as a high-strength yellow brass. It has an excellent combination of strength and ductility, and good resistance to corrosion. Among its applications are marine hardware, propellers and gears. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive strength as well as fracture toughness, creep, and fatigue. It also includes information on corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: Cu-369. Producer or source: Ampco Metal Inc..

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..

AMPCOLOY 570 is a cast copper-nickel-aluminum-cobalt-iron alloy specially developed for applications involving severe stresses and high temperatures, such as glass-making molds and plate-glass rolls. It is significantly superior to cast iron which has been commonly used for glass-making molds. Good foundry techniques will yield high-quality castings of Ampcoloy 570 in a wide range of section sizes. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: Cu-392.
