Zamak






Zamak ingot


Zamak (formerly trademarked as ZAMAK[1] and also known as Zamac) is a family of alloys with a base metal of zinc and alloying elements of aluminium, magnesium, and copper.


Zamak alloys are part of the zinc aluminium alloy family; they are distinguished from the other ZA alloys because of their constant 5% aluminium composition.[2]


The name zamak is an acronym of the German names for the metals of which the alloys are composed: Zink (zinc), Aluminium, Magnesium and Kupfer (copper).[2] The New Jersey Zinc Company developed zamak alloys in 1929. Zinc alloys are popularly referred to as pot metal or white metal. While zamak is held to higher industrial standards, it is still considered a pot metal.


The most common zamak alloy is zamak 3. Besides that, zamak 2, zamak 5 and zamak 7 are also commercially used.[2] These alloys are most commonly die cast.[2] Zamak alloys (particularly #3 and #5) are frequently used in the spin casting industry.


A large problem with early zinc die casting materials was zinc pest, owing to impurities in the alloys.[3] Zamak avoided this by the use of 99.99% pure zinc metal, produced by New Jersey Zinc's use of a refluxer as part of the smelting process.


Zamak can be electroplated, wet painted, and chromate conversion coated well.[4]

Mazak


In the early 1930s Morris Ashby in Britain had licensed the New Jersey zamak alloy. The high-purity refluxer zinc was not available in Britain and so they acquired the right to manufacture the alloy using a locally available electrolytically refined zinc of 99.95% purity. This was given the name Mazak, partly to distinguish it from zamak and partly from the initials of Morris Ashby. In 1933, National Smelting licensed the refluxer patent with the intent of using it to produce 99.99% zinc in their plant at Avonmouth.[5]

†color of the cell is the color of the material designated by ASTM B908.[2]

The Short European Designation code breaks down as follows (using ZL0430 as the example):[11]



  • Z is the material (Z=Zinc)

  • P is the use (P=Pressure die casting (casting), L=Ingot)

  • 04 is the percent aluminium (04= 4% aluminium)

  • 3 is the percent copper (3= 3% copper)



Zamak 2


Zamak 2 has the same composition as zamak 3 with the addition of 3% copper in order to increase strength by 20%, which also increases the price. Zamak 2 has the greatest strength out of all the zamak alloys. Over time it retains its strength and hardness better than the other alloys; however, it becomes more brittle, shrinks, and less elastic.[17]


Zamak 2 is also known as Kirksite when gravity cast for use as a die.[2][18] It was originally designed for low volume sheet metal dies.[19][20] It later gained popularity for making short run injection molding dies.[19] It is also less commonly used for non-sparking tools and mandrels for metal spinning.

Zamak 3


Zamak 3 is the de facto standard for the zamak series of zinc alloys; all other zinc alloys are compared to this. Zamak 3 has the base composition for the zamak alloys (96% zinc, 4% aluminium). It has excellent castability and long term dimensional stability. More than 70% of all North American zinc die castings are made from zamak 3.[2]

Zamak 5


Zamak 5 has the same composition as zamak 3 with the addition of 1% copper in order to increase strength (by approximately 10%[17]), hardness and corrosive resistance, but reduces ductility.[31] It also has less dimensional accuracy.[31] Zamak 5 is more commonly used in Europe.[2]

Zamak 7


Zamak 7 has less magnesium than zamak 3 to increase fluidity and ductility, which is especially useful when casting thin wall components. In order to reduce inter-granular corrosion a small amount of nickel is added and impurities are more strictly controlled.[2]

Quarantine

For other uses, see Quarantine (disambiguation). Signal flag "Lima" called the "Yellow Jack" which when flown in harbor means ship is under quarantine. A simple yellow flag (also called the "Yellow Jack") had historically been used to signal quarantine (it stands for Q among signal flags), but now indicates the opposite, as a signal of a ship free of disease that requests boarding and inspection. A quarantine is used to separate and restrict the movement of people; it is 'a restraint upon the activities or communication of persons or the transport of goods designed to prevent the spread of disease or pests', for a certain period of time. [1] This is often used in connection to disease and illness, such as those who may possibly have been exposed to a communicable disease. [2] The term is often erroneously used to mean medical isolation, which is "to separate ill persons who have a communicable disease from those who are healthy...
