It is the zinc aluminum alloy one uses in die casting with the lowest possible aluminum content. It features an aluminum content of 8.4 percent with one percent copper. Because of the minimal aluminum content, ZA 8 has a lower melting point and higher density than other zinc aluminum alloys.
Iron in Aluminum. Iron is necessary in aluminum die casting alloys because iron free liquid aluminum alloy aggressively attacks ferrous metals, including die steels, causing severe erosion. Aluminum also tends to stick, or solder, onto die surfaces. Iron in aluminum die casting alloys, in

Aluminum die casting defects Aluminum die casting defects is an undesired irregularity in a aluminium Die casting process .but it’s also a normal phenomenon .As 650°C molten aluminium material solidify into casting by high pressue.
Apr 19, 2016 · Zinc 3 is the most commonly used zinc alloy, and it is sometimes exclusively used by die casters because of its tendency to be priced lower. In addition, the alloy provides a better surface finish during higher production rates, and it’s still capable of casting stable,
Aluminum alloy die casting Preface. The chart below is from the Japanese Industrial Standards and is based on the information contained in ISO/FDIS 3522Aluminium and aluminium alloys Castings Chemical composition and mechanical properties published in 2006.
Reviews from Alloy Die Casting employees about Alloy Die Casting culture, salaries, benefits, work life balance, management, job security, and more.
The die casting process forces molten aluminum into a steel die (mold) under pressure. This manufacturing technique is normally used for high volume production. Precisely formed aluminum parts requiring a minimum of machining and finishing can be produced through this casting method.
Practically all zinc alloy diecastings contain some porosity, and “sound” is therefore not an absolute term. In zinc pressure die casting, the porosity originates from two sources. Firstly, from trapped air that is unable to escape from the runner system plus mould which are themselves sealed and filled by molten metal in milliseconds.

Approximately 85% of aluminum alloy die castings are produced in aluminum silicon copper alloys (alloy 380.0 and its several modifications). This family of alloys provides a good combination of cost, strength, and corrosion resistance, together with the high fluidity and freedom from hot shortness that are required for ease of casting.
Typically the casting temperature for AZ91 is in the range 650–680 °C for cold chamber casting, and 620–640 °C for hot chamber casting. Alloys with lower aluminum contents are cast at somewhat higher temperatures, 660–690 °C. The most common magnesium die casting alloy is AZ91D.
