Zamak alloys are part of the zinc aluminium alloy family; they are distinguished from the other ZA alloys because of their constant 4% aluminium composition. [ 2 ] The name zamak is an acronym of the German names for the metals of which the alloys are composed: Zink (zinc), Aluminium , Magnesium and Kupfer (copper). [ 2 ]
Tombac, or tombak, is a brass alloy with high copper content and 5–20% zinc content. [1] Tin , lead or arsenic may be added for colouration. [ 2 ] [ 3 ] It is a cheap malleable alloy mainly used for medals , ornament , decoration and some munitions .
This is a list of named alloys grouped alphabetically by the metal with the highest percentage. Within these headings, the alloys are also grouped alphabetically. Within these headings, the alloys are also grouped alphabetically.
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. Such toys are made of metal, with plastic, rubber, glass, or other machined metal parts.
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.
An inexpensive alloy that is easily cast and worked, spelter was used from the 1860s in the manufacture of candlesticks, clock cases, tableware, and light fixtures. In the early 20th century, sculptors such as Jacques Limousin used spelter heavily in their manufacture of Art Nouveau and Art Deco figurines and other ornaments.
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 .
The alloy typically consists of 85–88% copper and the remainder being zinc. It is also known by other names such as "composition gold leaf", "Dutch gold", "Schlagmetal" and "Schlag leaf". [1] It is very malleable and ductile and so can be beaten into very thin sheets. These sheets are sold for use as metal leaf or imitation gold leaf. [2]
