An alloy of 96% zinc and 4% aluminium is used to make stamping dies for low production run applications for which ferrous metal dies would be too expensive. [141] For building facades, roofing, and other applications for sheet metal formed by deep drawing, roll forming, or bending, zinc alloys with titanium and copper are used. [142]
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 ]
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.

Zinc–copper couple is an alloy of zinc and copper that is employed as a reagent in organic synthesis.The “couple” was popularized after the report by Simmons and Smith, published in 1959, on its application as an activated source of zinc required for formation of an organozinc reagent in the Simmons–Smith cyclopropanation of alkenes.

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 .
