ZAMAK 3（ZNAL4，ZPO400）

Zamak 3 is usually the first choice when considering a zinc die casting .  It has an excellent combination of physcial and mechanical properties, superb castability and long-term dimensional stability.  Nearly 70% of all zinc die castings are made from 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.

The appropriate industry：

Environmentally friendly die-cast zinc alloy -3# is suitable for Automobiles, Motorcycles, Electronic communications, Instruments and other Mechanical parts, as well as Toys, Ornaments, Tableware, Locks and other Hardware devices.

 

Performance feature：

  • This product meets the standards of China, the United States and the European Union;Comply with ROHS, EN71Part3, EN1811, CPSIA and other requirements;
  • Low remelting temperature, less slag content, and fine internal crystallization;
  • Good physical and mechanical properties, castability, dimensional stability and creep resistance.

 

Method of application

  • Bake and dry before use. Do not stir or dredge when feeding.The scum above the molten liquid is stirred calmly with a slag rake to collect it and remove it;
  • The nozzle material according to the ratio of 25%-30% input, no need to slag;
  • The best die casting temperature: 420℃-435℃, the best mold temperature: 210℃-230℃.The upper limit of die-casting temperature is recommended for thin-walled parts and complex parts, and the lower limit is recommended for thick-walled parts and simple parts.
  • The following phenomena may exist in the use process: there is a thin oil film on the surface of the alloy liquid, and there will be a small amount of black film, which is a normal phenomenon.
