Understanding Zinc Die Casting Fundamental

Zinc die casting is a process of manufacturing in which molten metals (molten zinc) alloy is forced into the highly engineered molds under high injection pressures in steel, utilizing high pressure for better results . The process produces dimensionally precise, complex-shaped parts with the outstanding quality of surface finish and superior strength . Hot chamber die cast zinc alloys possesses zinc’s superior casting fluidity that is extremely excellent and thus such alloy is suitable where complex designs are aimed to be used when thin walls and dimensions tolerances are desired.

The nature of zinc die casting is based on peculiarities of the material, contributing to material cost savings . The low melting point, high fluidity and good casting capability of Zinc allow the manufacturers to make durable components and parts having a tight tolerance such as high precision +/- 0.001 inches and achieve the same quality over longer production cycles.

Primary Zinc Die Casting Alloy Families

ZAMAK Alloy Series

The family of ZAMAK (Zinc- Aluminum- Magnesium- Copper) alloys are the most popularly used material in zinc die casting industrial uses for producing zinc die cast components . The alloys use the inherent characteristics of zinc alloys, with specific properties being improved by the relatively delicate addition of aluminum, magnesium and copper.

The most common zinc alloy used in die casting is zamak 3 due to the castability and the outstanding finishing properties. This alloy gives an ideal compromise and that is why it is used in so many die casting applications, particularly in the automotive industry where high precision and reliable performance compared to other metals is a requirement.

ZA Alloy Series

Overall the ZA alloys are stronger, harder and provide greater creep resistance than the Zn alloys and can be used where bearing properties are critical. ZA (Zinc-Aluminum) ZA-8, ZA-12, and ZA-27 alloys, known as za alloys, all have their unique benefits depending on any particular zinc die casting process applications where mechanical properties of a higher order and wear properties are required.

ZAMAK 3: The Industry Standard

ZAMAK 3 is one of the dominant materials in zinc die cast parts usage partly caused by its unique blend of properties, making die cast zinc suitable for a range of heat sinks and decorative coatings. Its advanced physical and mechanical outstanding properties, good castability and long term dimensional stability, along with the potential for lower production costs, are reasons why many choose it over other materials. This alloy has a content of about 4% of aluminum and 0.035 percent of magnesium that offer good strength to weight ratio and corrosion resistance, contributing to improved die casting production rates .

The elongation characteristics of the alloy allow crimping and swaging processes to be performed and thereby it is suitable in assembly that involve mechanical joining requirements to help reduce fabrication costs . ZAMAK 3 has an outstanding surface finish quality which enables different finishing options to be undertaken, such as plating, painting and powder coating without a rigorous surface preparation work, especially in shot chamber applications .

ZAMAK 5: Enhanced Strength Properties

The enhanced tensile strength as well as hardness of ZAMAK 5 is achieved by increasing the copper percentage as compared to ZAMAK 3, making it suitable for various applications in the zinc die casting process . The alloy offers about 10 percent greater strength and can be cast under high pressure with high rates of castability and dimensional stability. The improved mechanical characteristics result in the ability of ZAMAK 5 to be used for producing zinc parts under the heavier loads compared to its predecessors, surpassing performance of other casting processes .

The increased creep resistance of the alloy increases the service life of the zinc die cast components used in operations where constant loading is used. The machinability of zinc fabricated components like ZAMAK 5 is good, and with its superior creep resistance, secondary operations may be performed where necessary although the as-cast surface finish is so good in most applications no machining is necessary.

Advanced ZA-8 Alloy Properties

ZA-8 alloy has a much-improved strength and hardness level compared with the zinc alloy die casting traditional ZAMAK alloys because it has a lot of aluminium content about 8.4 per cent, providing excellent wear properties . The alloy has tensile strength of more than 290 MPa and good casting capabilities with high dimensional stability.

The higher the quantity of aluminum, the higher the strength-to-weight ratio of the alloy, something which makes the alloy appealing in areas where saving weight is paramount, such as in aircraft. The high level of bearing AB-8 and wear resistance qualifies it to be used in the mechanical fluid areas that experience sliding contact and have cyclic loading, contributing positively to die life .

High-Performance ZA-12 Characteristics

A wonderful bearing alloy, zinc ZA-12 can be plated as well, though the adhesion of the plating is less than what it is in the traditional alloys zinc. It is very powerful alloy with reported yield strength of 380 MPa (55ksi). Its proprietary strength characteristics are among the strongest available with design engineers capable of building lighter, more efficient electrical components with no loss of performance.

ZA-12 is an outstanding bearing material appropriate in bushings, gears as well as other parts that demand high wear resistance. Dimensional stability of the alloy enables the alloy to perform over long durations with little maintenance making the system more reliable.

ZA-27: Maximum Strength Applications

ZA-27 is the strongest alloy of zinc die casting alloy available with about 27 percent of the aluminum content. The alloy offers tensile strengths of more than 420 MPa but having very high properties of hardness and wear resistance. The two-phase microstructure due to the high content of Al, increases mechanical properties drastically.

The combination strength-to-weight ratio of the alloy comes close to that of the aluminum alloys, and retains zincs excellent casting properties. ZA-27 has excellent machinability enabling precision operations to be performed after the secondary casting operation where necessary but in most cases it does not necessitate any machinability due to the high as-casted dimensions of the material.

Mechanical Properties Comparison

Zinc die castings compared to other alloys are stronger, tougher, stronger, perform better and offer die casting production rates that lead to economically manufacture cast parts and cost-effective efficiencies. The die casting property of the zinc alloy usually surpasses the property of other alloys like the aluminum alloy, magnesium alloy/ bronze, other plastics and other cast irons.

Knowledge of the mechanical characteristics of the various zinc-alloys, therefore facilitates the best selection of a material to suit a particular job. Zenithal tensile strength of alloy grades is 260 mp (ZAMAK 3) and above 420 mp (ZA-27) respectively and the yield strength is 200 mp (ZAMAK 3) and 380 mp (ZA-27).

Surface Finish and Dimensional Accuracy

The alloy die cast zinc offers ductility and strength of impact, thin walls and good surface finish thus preparation of plating and painting is accessible for zinc die cast parts . The high quality of surface finish that zinc die casting can produce, usually obviates secondary finishing processes and so lowers production costs and lead times.
