Zamak 3

The most common zinc die casting alloy in North America. Usually the first choice when considering an alloy for zinc die casting due to its excellent combination of mechanical and physical properties, and superb casting and finishing ability.

Zamak 2

Within the Zamak family of alloys, Zamak 2 has the highest strength and hardness due to its higher copper content (3%). Also known as Kirksite when making tooling for the stamping or plastic injection mold industries.

Zamak 5

Commonly used zinc die casting alloy throughout the world due to its combination of strength, ductility and fluidity. The 1% additional copper added to the alloy improves the alloy's mechanical properties.

Zamak 7

Although magnesium is a useful element to combat corrosion effects of the alloy due to certain impurities, it was also found to reduce the alloy's fluidity. In this alloy, nickel replaced magnesium, which helped improve the fluidity and casting ability of the alloy. The properties are similar to Zamak 3 with enhanced fluidity.

ZA-8

Zinc alloy with 8% aluminum. The most common of the ZA alloys due to its combination of strength, casting ability (cast in a hot chamber machine), and is often electro-plated.

ACuZinc

A zinc die casting alloy developed in the 1990's by General Motors. ACuZinc is a zinc based alloy with approximately 5% copper and 3% aluminum. The combination AL/Cu/Zn in this alloy produces castings with exceptional mechanical and physical properties.

ZA-12

ZA-12 has an excellent combination of mechanical properties and casting ability. Due to its elevated aluminum content this alloy is cast in a cold chamber die casting machine.

EZAC

Zinc die casting alloy with the highest strength, hardness and creep resistance, along with exceptional fluidity.

ZA-27

Zinc alloy with 27% aluminum. This higher aluminum content offers an alloy with exceptional mechanical properties as well as the lowest density of all the zinc die casting alloys.

A380

A380 is the most common Aluminum Die Casting Alloy used in North America.

ZA-8 Permanent Mold

Zinc/Aluminum alloy with 8% aluminum. ZA-8 can be both gravity cast and die cast. The lower aluminum content allows this alloy to be easily electro-plated.

A383

A383 is a common aluminum die casting alloy with a higher content of silicon and lower copper. This alloy has slightly improved corrosion resistance, resistance to hot cracking, fluidity, and strength at elevated temperatures compared to A380.

ZA-12 Permanent Mold

ZA-12 is a zinc based casting alloy that can be both gravity cast and die cast. It is the most common gravity casting alloy with the best combination of properties and casting ability.

A356

A356 is the most common gravity casting alloy cast in North America. It has excellent fluidity, corrosion resistance, can be welded and heat treated (T5 and T6) to improve the casting's mechanical properties.

ZA-27 Sand Cast

Zinc/Aluminum alloy with 27% aluminum. ZA-27 can be both gravity cast and die cast, and is the strongest of the ZA alloys.

Kirksite

A moderate strength zinc-based alloy developed primarily as a forming tool alloy.

Galfan

Galfan is used on steel products requiring higher ductility/formability, with the same galvanic/physical barrier protection as galvanized products.

Slush Cast Alloy

Zinc based alloy used to form "hollow" decorative castings that are not subjected to high stress conditions.

Brightener Master Alloys

Eastern Alloys manufactures both the 95-5 brightener (5% aluminum) as well as the 90-10 brightener (10% aluminum) alloys, which are used to convert a Galvaneal coating bath back to a Galvanizing bath or to maintain the aluminum content in the galvanizing bath on an on-going basis.

Galvalume

Eastern Alloys manufactures "Pre-mixed" Galvalume for those manufacturing facilities who do not want the challenges associated with the alloying process. Such challenges include purchasing the various metals to alloy, melting, mixing, and analyzing the alloys to ensure quality. Eastern also manufactures Aluminum Silicon master alloys that are also used to simplify the alloying process for Galvalume.

Nickel-Zinc Master Alloy

Eastern Alloys manufactures a Nickel-Zinc Master alloys for the Hot-Dip Galvanizing process.

Aluminum-Silicon Alloys

Eastern Alloys manufactures Aluminum Silicon alloys for various steel coating applications including a master alloy in the Galvalume process as well as a coating alloy for Aluminized steel.
