Zamak 3
The most popular and widely used zinc alloy, known for its excellent balance of strength, ductility, and castability. It's ideal for die-casting applications, such as automotive parts, hardware, and toys. Zamak 3 offers good surface finish and dimensional stability.
Zamak 5
Similar to Zamak 3 but with higher copper content, which provides increased strength and hardness. This makes it suitable for mechanical components requiring extra durability, like gears and pump parts. Zamak 5 is also used in die-casting for decorative finishes.
Zamak 7
A variation of Zamak 3 with a lower magnesium content, resulting in improved ductility and fluidity. It's ideal for intricate die-castings, such as precision instruments and art objects, where fine detail and smooth surfaces are required.
ZA-8
A high-strength zinc-aluminum alloy, suitable for both die casting and permanent mold applications. ZA-8 is used when more strength than typical Zamak alloys is needed, such as in automotive safety components and electronic devices.
ZA-12
Offering a good balance between castability, strength, and cost-effectiveness, ZA-12 is used in various applications like engine components, business machines, and building hardware. It can be cast using various methods, including die, permanent mold, and sand casting.
ZA-27
The strongest of the ZA series, with the highest aluminum content. It's used in demanding applications that require high strength and low weight, such as high-speed machinery parts and aerospace components. ZA-27 has excellent bearing properties and is also used in high-load bearing applications.
