We recently published a list of 13 Best Magnesium Stocks to Buy Right Now. In this article, we are going to take a look at where POSCO Holdings Inc. (NYSE:PKX) stands against other best magnesium stocks to buy right now.

Magnesium is a key material used in various industrial applications. Magnesium chloride is commonly utilized for deicing roads and as an ingredient in fertilizers. Beyond its industrial uses, magnesium is essential to U.S. national security, as it supports critical sectors such as aerospace, defense, and steel production.

The automotive sector is one of the top magnesium consumers, owing to its lightweight properties, helping enhance fuel efficiency and vehicle performance. Top automakers have already started to use magnesium instead of steel and aluminum in several components, according to the International Magnesium Association. For example, a magnesium alloy wheel can reduce weight by 32% compared to aluminum. The shift toward lighter materials has helped the automotive sector meet stricter fuel economy and emission standards, transforming magnesium into an essential material in modern vehicle design.

As such, the global magnesium industry has seen strong growth in the past years, with its size forecasted to reach $4.97 billion in 2025, up from $4.67 billion in 2024, at a growth rate of 6.4%, as per The Business Research Company. This growth has primarily been driven by the rising demand for lightweight materials in the automotive industry, the increasing adoption of magnesium alloys in aerospace applications, and its widespread usage in medical implants as well as consumer electronics. The industry’s growth is also supplemented by government initiatives promoting magnesium.

Furthermore, magnesium has broader implications for efficiency due to its ability to reduce vehicle weight remarkably. According to estimates by the U.S. Automotive Material Partnership, using 150 lbs of magnesium instead of 500 lbs of steel, or 90 lbs of magnesium instead of 150 lbs of aluminum can help reduce vehicle weight by 15%. This property can save over 5 billion gallons of fuel by 2030 as magnesium gets integrated into 25% of the vehicles in the U.S. Such positives add to magnesium’s role in the shift of industry toward sustainability and cost efficiency.

Additionally, the increasing demand for battery electric vehicles (BEVs) further cement magnesium’s market. According to S&P Global Mobility, BEV sales worldwide are expected to reach 15.1 million units in 2025, a 30% surge from 2024. These sales would account for 16.7% of total light vehicle sales. As the automotive market shifts toward prioritizing weight reduction to increase battery range and efficiency, magnesium alloys are anticipated to play an important role in vehicle design.

Apart from the automotive sector, emerging trends in the magnesium market are powering innovation across sectors. Medical applications are driving the development of new magnesium-based materials, including biodegradable implants that dissolve naturally in the body, leaving no residue. This development could revolutionize the medical industry, providing more sustainable and safer options to traditional implant materials.

Additionally, as the world moves toward sustainable and recyclable materials, magnesium’s appeal is increasing in various sectors. The environmental impact of magnesium is expected to lower, as advancements are being made in magnesium recycling technologies, in line with global sustainability goals while potentially driving cost efficiency. The magnesium recycling market is expected to reach $1.03 billion by 2032, up from $558.8 million in 2023, increasing at a CAGR of 7.1%, according to Custom Market Insights. Such growth points toward the increasing role of recycled magnesium in addressing industrial demand, as well as reducing dependency on primary extraction.

Magnesium holds an essential position in the automotive and aerospace industries, driven by its high strength-to-weight ratio and high melting point. Around 70% of global magnesium produced is being used for alloy manufacturing currently, adding to its importance in structural applications. Thus, as various sectors look to move toward lightweight, durable, and eco-friendly materials, magnesium’s role is expected to grow in the global market, strengthening the trajectory of its long-term growth.
