Zamak-3 is usually the first choice when considering zinc die casting. Its excellent balance of desirable physical and mechanical properties, superb castability and long-term dimensional stability are the reasons why over 70% of all the world zinc die castings are in Zamak-3. It is, therefore, the most widely available alloy from die casting sources. Zamak-3 also offers excellent finishing characteristics for plating, painting and chromate treatments. It is the "standard" by which other zinc alloys are rated in terms of die casting.
