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. [30] It also has less dimensional accuracy. [30] Zamak 5 is more commonly used in Europe. [2]
Zamak 2, of a slightly different composition, was originally developed as a gravity-cast alloy with greater finished strength but was found to work well with spin-casting. Its extra copper content encourages the eutectic behaviour and gives a lower freezing point.
6, 5-10% potassium hexafluorozirconate K 2 ZrF 6, and 5-10% sodium fluoride NaF by weight. The formula was meant to be dissolved in water at the concentration of 9.0 g/L, giving a bath with pH = 1.5. It yielded a light gold color after 1 min, and a golden-brown film after 3 min. The average thickness ranged between 200 and 1000 nm. [6]
