Magnesium (Mg): Uses, Supply Chain and Market

Facts checked against sources on . How we check facts.

Magnesium metal is a lightweight structural metal used mostly in castings for the automotive industry and in aluminum alloys. In 2025 China produced an estimated 950 kt, 86% of world smelter production (USGS world total: 1,100 kt), according to the US Geological Survey (USGS). US net import reliance for magnesium in 2025 was more than 75%. Magnesium is on all four official critical minerals lists: the US, EU, Australian and Canadian.

How is magnesium mined and processed?

The only US primary magnesium smelter, in Utah, recovered magnesium from Great Salt Lake brines by an electrolytic process. Production stopped in 2022 and the operator filed for Chapter 11 bankruptcy protection in September 2025. Full page on how magnesium is mined and processed.

What is magnesium used for?

For secondary magnesium, about 58% was used in aluminum alloys and about 42% for structural uses.

  • Castings, principally for the automotive industry: 69% of US primary magnesium consumption in 2025
  • Aluminum-base alloys: 15%, used for packaging, transportation and other applications
  • Desulfurization of iron and steel: 9%
  • All other uses: 7%

Is magnesium a critical mineral?

Magnesium is on all four official critical minerals lists: the US, EU, Australian and Canadian. Each government builds its list with its own method, so a mineral can be critical in one place and not in another.

Export controls and trade measures

  • China has required export licenses for magnesium materials since 2024 (USGS Table 4).

See the export controls tracker for dates and current status.

What are the substitutes for magnesium?

USGS names substitutes for 2 applications of magnesium, for example castings and wrought products: aluminum and zinc; magnesium is lighter, but its high cost is a disadvantage. Full magnesium substitutes page.

Can magnesium be recycled?

About 26,000 tons of secondary magnesium was recovered from old scrap and 82,000 tons from new scrap in 2025. Aluminum-base alloys took about 53% of it and magnesium-based castings, ingot and other materials about 47%.

What are the supply risks and recent events for magnesium?

  • September 2025. The operator of the only US primary magnesium smelter, in Utah, filed for Chapter 11 bankruptcy protection. Primary production there fell sharply in September 2021 after equipment failures and stopped in 2022.
  • July to December 2025. A California company developing a magnesium-from-brine pilot plant, which won $19.6 million in Defense Production Act Title III financing in February 2024, produced a sample that met the purity target on a pilot scale. In December it announced plans for a commercial phase 1 plant in southwestern Arkansas.
  • 2025. US imports of magnesium metal (99.8% purity) fell 27% through August while imports of alloys rose 37% and of waste and scrap 48%. European prices were 13% lower on an annual-average basis than in 2024, which USGS attributed to maintenance closures and lower producer inventories in China.

Baowu Magnesium TechnologyChinaPrimary magnesium and magnesium alloy producer (SZSE: 002182)Its 2025 annual report, in Chinese, describes a chain from mine to primary magnesium to alloy using the vertical retort process, with three primary magnesium bases, and says its alloy output and sales have led the world for several years, which is its own claim. It quotes the China Nonferrous Metals Industry Association for domestic primary magnesium output of 1.0935 million tonnes in 2025 (up 6.6%) and alloy output of 428,400 tonnes (up 8.0%).

TETRA Technologies and Magrathea MetalsUnited States (Arkansas)Joint venture planned to make magnesium metal by electrolysis (NYSE: TTI)Their 2 December 2025 release announced a term sheet for a joint venture to rebuild the US magnesium metal industrial base at TETRA's Evergreen Project, a bromine plant being built near Stamps, Arkansas that is planned to begin operations by the end of 2027. It says Magrathea has already secured Defense Production Act Title III funding from the Department of War for its commercial phase 1, without an amount, and gives no magnesium capacity or start date.
