Terfenol-D (terbium, dysprosium, and iron), a highly magnetostrictive alloy used in portable speakers such as the SoundBug device; Ferrocerium (cerium, iron) Neodymium magnets, another strong permanent magnet; SmCo ; used for permanent magnets in guitar pickups, headphones, satellite transponders, etc. Scandium hydride
The practice of alchemy in the Western world, based on a Hellenistic and Babylonian approach to planetary astronomy, often ascribed a symbolic association between the seven then-known celestial bodies and the metals known to the Greeks and Babylonians during antiquity.
Corinth's location on a map of modern Greece. Corinthian bronze, also named Corinthian brass, aes Corinthiacum, or Grilver was a metal alloy in classical antiquity.It is thought to be an alloy of copper with gold or silver (or both), although it has also been contended that it was simply a very high grade of bronze, or a kind of bronze that was manufactured in Corinth.

Low-melting alloys, such as Bi-Cd-Pb-Sn alloy which melts at 70 °C (158 °F), are also used in automotive and aviation industries. Before deforming a thin-walled metal part, it is filled with a melt or covered with a thin layer of the alloy to reduce the chance of breaking. Then the alloy is removed by submerging the part in boiling water. [91]
A superalloy, or high-performance alloy, is an alloy with the ability to operate at a high fraction of its melting point. [1] Key characteristics of a superalloy include mechanical strength , thermal creep deformation resistance, surface stability, and corrosion and oxidation resistance.
Different atomic mechanisms of alloy formation, showing pure metal, substitutional, interstitial, and a combination of the two. When a molten metal is mixed with another substance, there are two mechanisms that can cause an alloy to form, called atom exchange and the interstitial mechanism. The relative size of each element in the mix plays a ...
Mangalloy, also called manganese steel or Hadfield steel, is an alloy steel containing an average of around 13% manganese. Mangalloy is known for its high impact strength and resistance to abrasion once in its work-hardened state.
Ti-6Al-4V titanium alloy commonly exists in alpha, with hcp crystal structure, (SG : P63/mmc) and beta, with bcc crystal structure, (SG : Im-3m) phases. While mechanical properties are a function of the heat treatment condition of the alloy and can vary based upon properties, typical property ranges for well-processed Ti-6Al-4V are shown below.
