Heusler alloys are magnetic materials made from three different metals that are not magnetic individually. The alloys are used broadly for their magnetic and thermoelectric properties, and their ability to regain their original shape after being deformed, known as shape memory. Investigations by Tohoku University's advanced materials scientist An-Pang Tsai and colleagues now show that these materials can also be fine-tuned to speed up chemical reactions. Heusler alloys have a typical composition of two parts metal X, one part metal Y, and one part metal Z (X2YZ). Each of the three come from a distinct region of the periodic table of elements. The original Heusler alloy, discovered in 1898, was Cu2MnAl, made from copper, manganese and aluminium. Many other combinations of met...

Researchers at the notorious Sandia National Laboratories in New Mexico - a primary supplier of US ancillary nuclear weapon systems - have announced the development of a two-metal alloy that is so hard that only diamond can compare in its ability to resist wear.

Engineers at Sandia National Laboratories have developed what they say is the most durable metal alloy ever created. Made up of a combination of platinum and gold, the new material is apparently 100 times more wear-resistant than high-strength steel, which makes it the first metal alloy to join the same class as diamond. Even better, it naturally produces its own lubricant that, under normal circumstances, is extremely fiddly and expensive to make.

Growing imports of manganese ore continued to buoy supplies of raw materials in 2018, even as environmental issues weighed on domestic production. Imports of manganese ore reached 22.08 million mt in January-October, compared to 21.26 million mt of total imports in 2017. This is likely to increase ore supplies by 15% year on year in 2018.
