Abstract Sterling Silver (Silversmiths grade) contains a minimum of 92.50% silver; the standard grade contains a minimum of 92.10% silver. Historically the remainder was unrestricted but copper was (and is) used because it is more desirable, in general, than other metals. Also, copper is a more effective hardener than other metals that have been considered; however, copper lowers the melting point substantially and lowers the electrical and thermal conductivities appreciably. Sterling Silver is used for flat and hollow tableware, various items of jewelry and special industrial applications. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on corrosion resistance as well as casting, forming, heat treating, and joining. Filing Code: Ag-11. Producer or source: Precious Metals Producers.

Abstract AMSULF is a free-machining copper combining high electrical and thermal conductivities with a machinability rating of 85% of free-cutting brass. (Conventional oxygen-bearing and oxygen-free coppers have ratings of 20%). AMSULF copper offers uniform machinability; in addition, it is resistant to hydrogen embrittlement because it is based on oxygen-free copper. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Cu-125. Producer or source: Amax Copper Inc..

Abstract UGIMA NSU and UGIMA 303 are the same grades designated differently for the European and North American markets, respectively. They are resulfurized grades with calcium added. Carefully controlled steelmaking results in a composition with oxides that have a low melting point and produce a lubricating effect during machining. Gains in the cutting conditions of 25 to 50% are typical on computer numerical control (CNC) lathe or classical machine work. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-709. Producer or source: Ugine-Savoie. Originally published March 1998, revised September 1998.
