China's Magnesium Sector Faces Oversupply and Price Challenges Despite Rising Output

China's Magnesium

China’s magnesium industry, which accounts for a staggering 83% of the world’s magnesium production, is grappling with challenges of oversupply and volatile prices, according to insights shared at the 27th annual conference of the China Magnesium Association (CMA) held in Xi'an.

Decade-Long Capacity and Utilization Issues

Over the past decade, China’s magnesium production capacity has ranged between 1.3 million and 1.5 million tonnes per year (t/yr). However, actual output has lagged behind at 800,000 to 1 million t/yr, resulting in an average utilization rate of just 63%, according to data from the China Nonferrous Metals Industry Association (CNMA).

Dependence on Traditional Sectors

The sector’s primary consumption is still tied to traditional industries like aluminium alloys, steel, and titanium sponge. Attempts to diversify into new applications, such as magnesium alloy construction sheets, consumer electronics, and new energy vehicles, have been slow. This limited innovation has contributed to an oversupply and pushed magnesium prices to near production costs.

Shifting Trends in Titanium Sponge Production

The use of magnesium in titanium sponge production has declined due to its environmental impact and price volatility. According to Jiang Baowei, lead engineer at Pangang Vanadium and Titanium Resources, many producers now use in-house magnesium obtained through electrolysis of titanium tetrachloride residue, reducing environmental pollution and stabilizing costs. In 2023, China’s titanium sponge production capacity reached 220,000 t/yr, supported by 250,000 t/yr of in-house electrolytic magnesium production.

Rising Production Amid Challenges

Despite these hurdles, China’s magnesium production rose to 702,900 tonnes during January-September 2024, an 18% year-on-year increase, fueled by resumed production in Shaanxi, the country’s largest magnesium-producing region. Output in Shaanxi grew by 14%, while neighboring Shanxi saw a 10% rise. Shaanxi alone houses 50 producers with a combined capacity of 678,000 t/yr, including 34 producers in Fugu County.

CMA’s Call to Action

Ge Honglin, CNMA president, urged the industry to emphasize magnesium’s benefits as a light structural metal and explore emerging markets like hydrogen storage and new energy vehicles. He also called for price stabilization to ensure affordability and reduce market volatility.

Sustainable Production Gains

The industry has made strides in energy efficiency, reducing the energy required to produce 1 tonne of magnesium from 5.2 tonnes of standard coal in 2012 to just 4 tonnes in 2023. Over the same period, magnesium consumption in structural materials more than doubled to 192,100 tonnes, contributing to a sharp rise in overall consumption, up by 76% since 2012.

China’s magnesium sector continues to grow in global prominence, but it faces an urgent need to diversify its applications, reduce environmental impacts, and stabilize pricing to maintain its leadership in the global market.
