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 ...
Fire-retardant materials should not be confused with fire-resistant materials. A fire resistant material is one which is designed to resist burning and withstand heat. An example of a fire-resistant material is one which is used in bunker gear worn by firefighters to protect them from the flames of a burning building.
These alloys are marketed under the name Zamak. ... zinc has been proposed as a salting material for ... PRIs increase from 7.5 to 12.7 mg/day as phytate intake ...
The later high-purity Zamak alloy avoided this problem. Lesney began making die-cast toys in 1947. Their popular Matchbox 1–75 series was so named because there were always 75 different vehicles in the line, each packaged in a small box designed to look like those used for matches. These toys became so popular that the "Matchbox" became ...
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.
Generally, the casting materials used for competing processes like metal die casting and injection molding are similar, but not suitable for spin casting. For example, a typical zinc die-casting alloy such as Zamak 3 can be used but will solidify too rapidly from a molten state when cast with centrifugal force.

The material used for the slide in the .380 ACP pistols is a zinc-aluminum alloy known as ZAMAK. [3] The guns chambered in 9x19 Parabellum, .357 SIG and .40 S&W used steel slides and were all locked breech firearms using the short recoil system developed by John Browning .
