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% aluminum). 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]
ZA alloys make good bearings because their final composition includes hard eutectic zinc-aluminium-copper particles embedded in a softer zinc-aluminium matrix. The hard particles provide a low-friction bearing surface, while the softer material wears back to provide space for lubricant to flow, similar to Babbitt metal .

Toy road roller cast from zinc. Pot metal (or monkey metal) is an alloy of low-melting point metals that manufacturers use to make fast, inexpensive castings. The term "pot metal" came about because of automobile factories' practice in the early 20th century of gathering up non-ferrous metal scraps from the manufacturing processes and melting them in one pot to form into cast products.
The metal must be molten prior to introduction into the mold. It is necessary for a spin casting furnace to have a temperature controller, as there is an optimal range for each metal. For example, a particular zinc alloy is typically cast between 413 and 427 °C (775 and 801 °F), whereas it actually melts much lower around 260 °C (500 °F).
A widely used zinc alloy is brass, in which copper is alloyed with anywhere from 3% to 45% zinc, depending upon the type of brass. [125] Brass is generally more ductile and stronger than copper, and has superior corrosion resistance. [125] These properties make it useful in communication equipment, hardware, musical instruments, and water ...
In the early days, as mentioned, it was common for impurities in the alloy to result in zinc pest, and the casting would distort, crack, or crumble. As a result, die-cast toys made before World War II are difficult to find in good condition. The later high-purity Zamak alloy avoided this problem. Lesney began making die-cast toys in 1947.
