Acuzinc5（ZNAL3CU5，ZP0350）

ACuZinc was developed by General Motors in the 1990's and has improved tensile strength, hardness and creep performance compared to the Zamak alloys.  Its strength, hardness and wear properties are comparable to ZA-12.  Although ACuZinc can be cast in a hot chamber die casting machine, it is known to be more difficult to cast with a higher wear rate of the shot end components in the die casting machine.

The appropriate industry：

 Environmentally friendly die-cast zinc alloy -Acuzinc5  is widely used in many fields, including but not limited to:

  • Automotive manufacturing: used to manufacture the shell, valve rod and other key parts of the automotive transmission system to ensure the performance and safety of the vehicle.
  • Electronic products: In the electronics industry, Zamak 2 is often used to manufacture electronic equipment housings, plugs and other components, to protect the internal circuit from the external environment.
  • Other industrial fields: In addition, the alloy is also used in the manufacture of door locks, handles, pull rings, zippers and other hardware accessories, as well as mechanical parts, tools, etc.

 

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: 535℃-580℃, 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.
