Copper Alloy No. 844 is a free-cutting copper-tin-lead-zinc alloy for castings; it was formerly identified as 81-3-7-9 alloy. It is characterized by good casting properties, moderate strength and ductility, good machinability and good resistance to corrosion. It is used widely for fittings, plumbing goods and valves. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: Cu-349. Producer or source: Copper alloy foundries.

SeBiLOY I (UNS C89510) is a selenium/bismuth-modified cast red brass alloy. Its low lead content helps meet the National Sanitation Foundation’s standard on low lead pickup in water supply systems. The Se/Bi modification permits machining similar to some of the red brasses it is replacing. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on casting, machining, and joining. Filing Code: CU-605. Producer or source: Copper and copper alloy mills.

SeBiLOY II (UNS C89520) is a selenium/bismuth-modified cast red brass alloy. Its low lead content helps meet the National Sanitation Foundation’s standard on low lead pickup in water supply systems. The Se/Bi modification permits machining exactly like the leaded red brasses it is replacing. This datasheet provides information on composition and physical properties. It also includes information on casting, machining, and joining. Filing Code: CU-606. Producer or source: Copper alloy producers.

EnviroBrass III is one of a series of alloys pursued by an industry consortium to develop alloys that meet the National Sanitation Foundation’s standard on low lead pickup in water supply systems. The research showed that a combination of bismuth and selenium provides the same beneficial effect on machinability as does lead. EnviroBrass III contains up to 1.2% Bi and 0.1% Se and is suitable for permanent mold and pressure die castings. SeBiLOY was the original name used to represent these alloys (see SeBiLOY I, Alloy Digest Cu-605, June 1996, and SeBiLOY II, Alloy Digest Cu-606, revised October 1996). This datasheet provides information on composition, hardness, and tensile properties. It also includes information on casting and machining. Filing Code: CU-662. Producer or source: Copper and copper alloy mills.

Federalloy I-836 (C89833) is a lead-free bronze casting alloy that is machinable by alloying additions of bismuth. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive strength as well as fracture toughness. It also includes information on corrosion resistance as well as casting, machining, and joining. Filing Code: CU-612. Producer or source: Federal Metal Company.

Federalloy I (C89837) is a lead-free brass casting alloy that is machinable by alloying additions of bismuth. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive strength as well as fracture toughness. It also includes information on corrosion resistance as well as casting, machining, and joining. Filing Code: CU-614. Producer or source: Federal Metal Company.
