ZA-12 is a zinc-aluminum-copper foundry alloy recommended for general-purpose castings of high strength at moderate cost. Its properties are similar to those of cast iron; however, it was designed for use in nonferrous foundries to compete with cast-iron, bronze, brass and aluminum castings. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive and shear strength as well as fracture toughness and fatigue. It also includes information on corrosion and wear resistance as well as casting, forming, heat treating, machining, and surface treatment. Filing Code: Zn-31.

KIDD Alloy ZA-12 is the general-purpose, zinc-aluminum-copper foundry alloy. It can be sand, permanent-mold or die cast. Alloy ZA-12 has a modest cost and a tensile strength suitable for many applications where bronze and cast or malleable iron were traditionally used. Alloy ZA-12 is extremely resistant to galling, has natural lubricity and is thus well suited to lubricated bearing and bushing applications. It is particularly well suited to liquid and gas-pressure applications. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength as well as fracture toughness and fatigue. It also includes information on casting, forming, heat treating, machining, and surface treatment. Filing Code: Zn-38. Producer or source: Kidd Creek Mines Ltd.

ZA-12 is the intermediate member of the family of three ZA die-casting alloys. Its melting point, solidification range and recommended casting-temperature range are greater than those of ZA-8. (See Alloy Digest Zn-48, January 1990). Due to these factors, ZA-12 must be die cast in cold chamber die-casting machines like conventional aluminum die-casting alloys. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive and shear strength as well as fracture toughness and fatigue. It also includes information on corrosion resistance as well as forming, machining, and surface treatment. Filing Code: Zn-49. Producer or source: Aluminum Smelting and Refining Company Inc..

ZA-27 is the strongest, hardest and lightest of the three-member ZA alloy group (see also ZA-8, Alloy Digest Zn-48, January 1990, and ZA-12, Alloy Digest Zn-49, May 1990). Mechanical properties of ZA-27 compare favorably with many heavier more costly (manufacturing intensive) alloys such as malleable and ductile iron, manganese and aluminum bronzes and many ferrous and nonferrous wrought alloys. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive and shear strength as well as fracture toughness and fatigue. It also includes information on corrosion resistance as well as casting, forming, machining, and surface treatment. Filing Code: Zn-50.

ZA-27 is a zinc-aluminum-copper alloy that offers exceptionally high strength (58,000 to 64,000 psi tensile strength as cast) at modest cost. It performs best in thin-walled castings (down to 0.10 inch) which means reduced weight and lower material costs when castings are redesigned. It is similar to the general-purpose ZA-12 alloy (Alloy Digest Zn-31, September 1977) except for its higher strength and elongation, but with higher casting temperatures and poor heavy-section castability. This datasheet provides information on composition, physical properties, hardness, tensile properties, and shear strength as well as fracture toughness and creep. It also includes information on corrosion and wear resistance as well as casting, forming, heat treating, machining, and surface treatment. Filing Code: Zn-32.

ZA-8 is a hypereutectic zinc-aluminum,highperformance die casting alloy. It is one of a family of three ZA Alloys which can be economically die cast with properties surpassing conventional zinc or aluminum alloys. It is the lowest aluminum content alloy of the family and it has the lowest melting point and casting temperature range. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive and shear strength as well as fracture toughness and fatigue. It also includes information on corrosion resistance as well as forming, machining, and surface treatment. Filing Code: Zn-48. Producer or source: Aluminum Smelting and Refining Company Inc..

HIDUMINIUM RR56 is a heat-treatable aluminium-base alloy recommended for general purpose forgings. It enables production of material which is readily worked in the hot stage and gives high mechanical properties, both for structural use and for use at moderately elevated temperatures. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive and shear strength as well as fatigue. It also includes information on high temperature performance as well as forming, heat treating, machining, and joining. Filing Code: Al-7. Producer or source: High Duty Alloys Ltd.

VANASIL 77 is an age-hardenable hypereutectic aluminum-silicon casting alloy having a low coefficient of thermal expansion and excellent wear resistance. These factors, combined with excellent high-temperature strength make it an excellent material for applications where light weight is required in combination with excellent wear resistance, dimensional stability, and high strength. Permanent molding is required to control properties. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on high temperature performance, corrosion and wear resistance as well as casting, heat treating, machining, and joining. Filing Code: Al-208.
