Zinc Alloys Have Favorable Casting Characteristics

Zinc alloys are widely used in a variety of industries and applications, including in the automotive and architectural industries. Zinc alloys can be defined as metal alloys made up of zinc and other metals.

Here are some zinc alloys that have favorable casting characteristics:

AZ92 (ASTM A792) or AZ101 (ASTM B101) :

A lead-free creep-resistant brass with good high-temperature strength up to 190C. Suitable for many applications requiring long-term resistance to corrosion and erosion, as well as high-temperature conditions.

AZ56A (ASTM B556) :

A high-strength zinc-aluminum alloy is widely used for components requiring a combination of high strength and stress corrosion resistance with good formability and weldability. It is also used as a friction alloy in both brake linings and clutch facings.

AZ91D (CZ105) :

A marine brass with enhanced machinability designed for the production of parts requiring excellent stress corrosion resistance at temperatures up to 50C below the water freezing point in fresh water and good resistance over a wider temperature range in salt water. It is commonly used for marine fittings, deck hardware, kitchen equipment, and appliances.

AZ80 (CZ80) :

A very versatile, leaded, high-strength brass with good formability, machinability, and weldability. It is used for parts requiring good strength at low temperatures, particularly in the automotive industry where it is extensively used for valve components.

X-750 (CZ105A) :

A zinc-copper alloy with improved tensile strength and increased resistance to stress corrosion cracking in chlorinated media. It also has good ductility at low temperatures. Used in architectural and industrial applications.

A286 (B275) :

A good-formability brass that can be easily machined and welded, but with excellent resistance to stress corrosion cracking, and sulphidation. It is widely used in the production of fittings such as pipes and ducting due to its high strength at temperatures up to 150C.

CZ52 (CZ52) :

A zinc-iron-chromium alloy with excellent creep resistance, good formability, and weldability. It is widely used in the automotive industry where it is used for engine components, bearing shells, and vehicle underbody applications such as chassis subframes, floor pans, and chassis cross members.

Factors That Affect the Quality of the Zinc Alloys Used in die casting

The quality of the zinc alloys used in the best custom zinc die casting can be affected by several factors, including the composition of the alloy, the manufacturing process, and the conditions under which the alloy is cast. The most important factor, however, is the composition of the alloy. The composition of the alloy must be carefully controlled to achieve the desired properties.

Alloys with low tin content are more ductile and easier to machine than those with high tin content. Therefore, these alloys are more often used in automobile manufacture. Low-tin alloys are also better suited for making thin-wall products because they cool faster than those with high tin content. But if low-tin alloys are cooled too quickly they will crystallize into brittle phases that will not hold up well under use or service.


There are many different types of alloys in the zinc family, and the properties of individual alloy grades can vary from batch to batch and even from lot to lot. To gain an understanding of all the properties and characteristics of a particular type of zinc alloy, it is important to use a major alloy reference standard.
