The oldest known pills were made of the zinc carbonates hydrozincite and smithsonite. The pills were used for sore eyes and were found aboard the Roman ship Relitto del Pozzino, wrecked in 140 BC. [78] [79] The Berne zinc tablet is a votive plaque dating to Roman Gaul made of an alloy that is mostly zinc. [80]
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]
Zinc, cadmium and mercury form a large range of alloys. Among the zinc containing ones, brass is an alloy of zinc and copper. Other metals long known to form binary alloys with zinc are aluminium, antimony, bismuth, gold, iron, lead, mercury, silver, tin, magnesium, cobalt, nickel, tellurium and sodium. [11]
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.
Pewter (/ ˈ p juː t ər /) is a malleable metal alloy consisting of tin (85–99%), antimony (approximately 5–10%), copper (2%), bismuth, and sometimes silver. [1] In the past, it was an alloy of tin and lead , but most modern pewter, in order to prevent lead poisoning , is not made with lead.
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 .
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.
White bronze is a white-coloured alloy. Examples of various alloys composed of copper, tin and zinc or composed of zinc, copper, aluminum and magnesium. [1] [2] A modern composition contains 55% copper, 30% tin and 15% zinc. [3] A 1904 patent for "white bronze" is composed of 86% zinc, 9.9% copper, 4% aluminum and 0.1% magnesium. [1]
