The Most
Versatile Metal

Magnesium is the lightest structural metal in use today. As such it is an attractive material for the automotive, aerospace and defence industries. It is 36% lighter per unit volume than aluminum and 78% lighter than iron. When alloyed, magnesium has the highest strength-to-weight ratio of all the structural metals.



Our Mission:

At REE-Magnesium  Inc., our main mission is to refine rare earth elements, Magnesium and other strategic metals using our proprietary processes and technologies. All our technologies used in refining these metals are environmentally neutral and cost-effective.

Pure magnesium burns vigorously, but magnesium alloys have higher melting points and are widely used in the aerospace and automotive part manufacturing. Magnesium alloys can withstand highly elevated-temperature applications. The new magnesium alloys, use calcium and strontium or Rare Earth Elements with sufficient creep resistance at elevated temperatures. These alloys are used in components such as engine blocks and power trains. MI is the only refinery in the United States that is licensed by CVMR® to manufacture these magnesium alloys.



Magnesium is considered to be a superior choice material in the areas of defense and aerospace engineering for aircraft and missile components; aircraft engine mounts, control hinges, fuel tanks, and wings, all use alloys of magnesium. In the automotive and motorcycle sectors, magnesium is used for wheels, housings, transmission cases, engine blocks, steering wheels and columns, seat frames and electronics. The use of magnesium and its alloys in automotive components was limited in the early sixties and seventies, but today fuel savings and environmental protection through reduced CO2 emissions have substantially increased its demand.


In structural applications, where weight plays a major role, magnesium is by far a superior choice. Laptop computers, television sets, cell phones and many other electronic devices use magnesium as a primary metal.

Magnesium is also a critical nutrient necessary for our bodies to function well. Magnesium deficiency has far reaching consequences, from Alzheimer’s and Asthma, to back pain, blood pressure, colon cancer, diabetes, cirrhosis of liver, toxic shock syndrome, urinary incontinence among many other illnesses, all can be traced often to a dietary deficiency in magnesium. Magnesium is such a vital part of our biology that by simply adding it to our diet as a nutritional supplement can reverse a whole slew of health issues.


Magnesium salts are included in various foods, fertilizers, paper production, fireproofing wood, mothproofing textiles and electrical insulators. Magnesium compounds, primarily magnesium oxide, are used as a refractory material in furnace lining to produce iron, steel, nonferrous metals, glass and cement.



According to the “U.S. Geological Survey, Mineral Commodity Summaries of 2016,” the latest official data available to the public, the following are the primary source production figures for magnesium:

World 910 000 tonnes1
China 800 000 tonnes1
U.S. 70 000 tonnes2
Russia 30 000 tonnes1
Israel 25 000 tonnes1
Kazakhstan 20 000 tonnes1

By the early 1990s the amount of magnesium produced in China was negligible, about 5% of total world consumption. Today China supplies 90% of the world’s consumption of pure and alloyed magnesium. This in turn has resulted in the shutdown of plants in many countries. The usual manufacturing processes of magnesium require large amounts of energy. This has been a fundamental reason that has made production of magnesium in many countries uneconomic.  Magnesium production in Western Europe is almost completely dependent on imports from China.
