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.

Federalloy I-844 (C89831) is a lead-free bronze casting alloy that is machinable by alloying additions of bismuth. Applications include bearings (high speed and heavy pressure), pumps, impellers, and corrosion-resistant and pressure-tight castings. 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 and joining. Filing Code: CU-611. Producer or source: Federal Metal Company.

Nibron Special is an extra high-strength nickel bronze that is corrosion resistant in both marine environments and industrial media. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as machining and joining. Filing Code: Cu-844. Producer or source: Columbia Metals Ltd.

Concast C89833 is a lead-free casting alloy that can be interchangeable with C836 (Alloy Digest Cu-317, August 1976). C89833 is classified as a bismuth tin bronze. See also Federalloy I-844, Alloy Digest Cu-611, March 1997. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. Filing Code: Cu-891. Producer or source: Concast Metal Products Company.

Carlson Alloy 904L is a 21Cr-24Ni-4.5Mo-1.5Cu low-carbon austenitic alloy that resists corrosion in a wide range of both oxidizing and reducing environments. It has good pitting and crevice-corrosion resistance and eliminates stress-corrosion cracking in most common chloride environments. The alloy resists intergranular corrosion in postwelded or stress-relieved conditions because of its very low carbon content. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-844. Producer or source: G.O. Carlson Inc.

AK Steel Nitronic 30 has good wet abrasion resistance, good resistance to aqueous and atmospheric corrosion, high strength, economy, and improved stress-corrosion cracking resistance over common 18-8 stainless steels. 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 forming and joining. Filing Code: SS-1138. Producer or source: AK Steel Corporation.

AK Steel Types 430, 434, 435 Mod, and 436 are ferritic stainless steels that provide a combination of corrosion resistance, functionality, and beauty that make them suitable for many roll-formed and stamped automotive trim applications. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming and joining. Filing Code: SS-1314. Producer or source: AK Steel Corporation.
