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 ...
Zinc pest (from German Zinkpest "zinc plague"), also known as zinc rot, mazak rot and zamak rot, is a destructive, intercrystalline corrosion process of zinc alloys containing lead impurities. [1] While impurities of the alloy are the primary cause of the problem, environmental conditions such as high humidity (greater than 65%) may accelerate ...

Typical early Dinky die-cast toy, with multiple parts and rubber tires, but early models had no glazed windows. A die-cast toy (also spelled diecast, or die cast) is a toy or a collectible model produced by using the die-casting method of putting molten lead, zinc alloy or plastic in a mold to produce a particular shape.
1:18 scale diecast replicas are 1/18th the size of the real vehicle. Most popular in this category are 1:18 scale automobile replicas – usually made out of Zamak zinc diecasting alloy [1] with plastic parts. "1:18 scale" is the colloquial reference to this class of toy or replica.

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. [ citation needed ] The numbers associated with the name represent the amount of aluminium in the alloy (i.e. ZA8 has 8% aluminium).
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.
