Zamak could be electroplated, moist painted, and chromate conversion coated effectively.[4]

Mazak[edit]
The 99.99%-purity refluxer zinc was not out there in Britain and they also acquired the fitting to fabricate the alloy utilizing a regionally out there electrolytically refined zinc of 99.95% purity. Within the early Thirties Morris Ashby in Britain had licensed the New Jersey zamak alloy. In 1933, Nationwide Smelting licensed the refluxer patent with the intent of utilizing it to provide 99.99% zinc of their plant at Avonmouth.[5]
Requirements[edit]
The Brief European Designation code breaks down as follows (utilizing ZL0430 as the instance):[11]
Zamak 2[edit]
The KS alloy was developed for spin casting ornamental elements. It has the identical composition as zamak 2, besides with extra magnesium with a purpose to produce finer grains and scale back the orange peel impact.(*5*)
Zamak 3[edit]
Zamak 3 is the de facto customary for the zamak sequence of zinc alloys; all different zinc alloys are in comparison with this. Zamak 3 has the bottom composition for the zamak alloys (96% zinc, 4% aluminum). Greater than 70% of all North American zinc die castings are created from zamak 3.[2]
Zamak 4[edit]
Zamak 4 was developed for the Asian markets to scale back the consequences of die soldering whereas sustaining the ductility of zamak 3. This was achieved by utilizing half the quantity of copper from the zamak 5 composition.[27]
Zamak 5[edit]
Zamak 5 has the identical composition as zamak 3 with the addition of 1% copper with a purpose to enhance power (by roughly 10%[17]), hardness and corrosive resistance, however reduces ductility.[30] It additionally has much less dimensional accuracy.[30] Zamak 5 is extra generally utilized in Europe.[2]
