Magnesium Alloy Metal Die Casting Services for Lightweight Parts
As industries push for lighter, stronger, and more efficient components, magnesium alloy metal has become an increasingly popular choice for die casting. Its exceptional strength-to-weight ratio, thermal conductivity, and recyclability make it ideal for applications in automotive, aerospace, electronics, and more.
In this article, we explore the key advantages of magnesium alloy die casting and how it compares to other metals—plus how OEMs can benefit from professional magnesium die casting services.
What Is Magnesium Alloy Metal?
Magnesium alloy metal is a blend of magnesium with other elements like aluminum, zinc, manganese, and rare earths. These alloys combine lightweight properties with good mechanical strength, making them ideal for high-performance, weight-sensitive applications.
Magnesium is the lightest structural metal available, approximately 33% lighter than aluminum and 75% lighter than steel.
Global Magnesium Alloy Usage and Trends
Magnesium alloys have seen fluctuating demand and production levels in recent years.
- Global Production: In 2022, global magnesium production will reach approximately 1.053 million tons, marking a 3.3% decrease from the previous year.
- China's Dominance: China will produce about 933,300 tons of magnesium in 2022, accounting for 88.63% of global production.
- Automotive Industry: The push for vehicle lightweighting has led to increased use of magnesium alloys. In 2023, China's demand for magnesium alloy automotive die-cast parts grew by 10% year-on-year, with projections indicating a 9.1% increase in 2024.
- Future Projections: By 2030, China's demand for magnesium alloy automotive die-cast parts is expected to reach approximately 1.37 million tons, with a compound annual growth rate (CAGR) of around 15% from 2025 to 2030.
