Zamak alloy primarily consists of zinc and aluminum in addition to other metals. The main components of Zamak 3 alloy have about 96% zinc and a small percent of aluminum. But there are other metals in a very small amount. The below list shows all the components of Zamak 3:
- Aluminum (Al) – 3.8 – 4.2%
- Magnesium (Mg) – 0.035 – 0.06%
- Lead (Pb) – 0.003%
- Copper (Cu) – 0.03%
- Iron (Fe) – 0.02%
- Nickel (Ni) – 0.001%
- Cadmium (Cd) – 0.003%
- Tin (Sn) – 0.001%
- Silicon (Si) – 0.02%
There are two categories of Zamak 3 properties. Mechanical properties and physical properties.
