The machinability of magnesium alloys is the best of any commercial metal, and in many applications, the savings in machining costs more than compensate for the increased cost of the material. [ citation needed ] It is necessary, however, to keep the tools sharp and to provide ample space for the chips.
Magnesium is the third-most-commonly-used structural metal, following iron and aluminium. [58] The main applications of magnesium are, in order: aluminium alloys, die-casting (alloyed with zinc), [59] removing sulfur in the production of iron and steel, and the production of titanium in the Kroll process.

The "Final 2023 Critical Materials List" was determined by the United States Department of Energy (DOE), [5] with the Undersecretary for Science and Innovation involvement. . This list incorporates materials deemed critical for energy applications and minerals from the 2022 final list designated by the Department of the Interior through the United States Geological Survey (USG
Dissimilar friction stir welding (DFSW) is the application of friction stir welding (FSW), invented in The Welding Institute (TWI) in 1991, [1] to join different base metals including aluminum, copper, steel, titanium, magnesium and other materials. [2] It is based on solid state welding that means there is no melting.
A report by the National Academy of Sciences [6] concluded that these center based programs were instrumental in defining "materials science and engineering" as a new interdisciplinary activity which was evidenced by a rapid increase of materials science departments between 1960 and 1970 and beyond. In addition, to the building of new ...
Die casting machines and cells including the peripheral equipment for molten-metal casting, magnesium die casting, semi-solid metal casting, squeeze-casting and vacuum applications. Process technology and systems for dispersion and true grinding applications such as printing inks, paints, coatings, pigments and colorants, electronic materials ...
The technology was proposed in 2009 based on magnesium and antimony separated by a molten salt. [31] [32] [33] Magnesium was chosen as the negative electrode for its low cost and low solubility in the molten-salt electrolyte. Antimony was selected as the positive electrode due to its low cost and higher anticipated discharge voltage.
Aluminium-magnesium alloys are considered to be very corrosion-resistant, making them suitable for marine applications, but this is only true if the -phase exists as a non-contiguous phase. Alloys with Mg contents below 3% are therefore always corrosion-resistant, with higher contents, appropriate heat treatment must ensure that this phase is ...
