Other non-ferrous metals and alloys
Published in William Bolton, R.A. Higgins, Materials for Engineers and Technicians, 2020
A wide range of components, both for the engineering industries and for domestic appliances, is produced in a number of different zinc-based alloys. A family of such alloys was developed in 1929 in the United States and is known as Zamak, this being an acronym for Zinc, Aluminium, Magnesium and copper (Kupfer in German). In Britain in the early 1930s, the name Mazak was used for this family of alloys.

The most widely used zinc-casting alloy is called alloy No. 3, sometimes referred to as Zamak 3. It has 4% aluminum and 0.035% magnesium. Another is called Zamak 5, and it also contains 4% aluminum with 0.055% magnesium and 1.0% copper. A group of alloys having higher aluminum content are the ZA alloys, with ZA-8, ZA-12, and ZA-27 being very popular. The strength properties of cast ZA-12 zinc alloy are listed in Appendix A–11.

Zn–Al alloys have been widely studied as they present various applications in the industry, e.g. protective layers on steel items [1–5], sacrificial anodes for corrosion protection of marine equipment [6–9], high-temperature solders [10–15] and bearing materials [16–20]. Due to its improved wear resistance, lack of environmental impact and lower production cost, Zn–Al alloys have been used to replace the traditional bronze bearing [21,22]. The commercial denomination of Zn–Al-based alloys is Zamac or Zamak, or simply ZA. The most common Zamac alloys are ZA-8, ZA-12 and ZA-27, where the number represents the aluminium content in weight per cent in the alloy.
