Magnesium Alloy Casting
Custom magnesium alloy die casting housings designed for lightweight structures, equipment assemblies, and industrial applications.
1. Product Overview
Magnesium alloys are alloys based on magnesium with the addition of other elements. Known as “the green material of the 21st century,” they are one of the best material solutions for achieving the “dual carbon” strategy. Magnesium alloy castings are components produced by casting methods, and they are classified into cast magnesium alloys and wrought magnesium alloys according to the forming method, with cast magnesium alloys being far more widely used than wrought alloys.
Magnesium alloys are abundant in resources and offer outstanding advantages such as low density, high specific strength and specific stiffness, excellent damping capacity for vibration and noise reduction, electromagnetic shielding capability, and good recyclability. The density of magnesium is approximately 1.8 g/cm³, which is only about 2/3 that of aluminium and 1/4 that of steel. Thanks to their remarkable lightweight properties, magnesium alloy castings are now widely used in automotive manufacturing, aerospace, 3C electronics, national defence, military industries, rail transit, and many other fields.
Our products strictly comply with national standards including GB/T 13820-2018 Magnesium Alloy Castings, GB/T 1177-2018 Cast Magnesium Alloys, and GB/T 25747-2022 Magnesium Alloy Die Castings. The performance and quality of our products meet internationally advanced levels.
2. Product Classification
2.1 By Alloy System
Cast magnesium alloys are mainly divided into the following three major alloy systems:
(1) Mg‑Al System Alloys
Cast magnesium alloys with aluminium and zinc as the main alloying elements. This is currently one of the most cost‑effective and efficient forming magnesium alloy systems. Typical grades include AZ91D, AM60, AM50, AE44, ZM5, ZM10, etc. Mg‑Al system alloys are mainly used for pressure die casting due to their excellent formability and good strength. Among them, AZ91D is the workhorse of the magnesium die‑casting industry, accounting for about 90% of all applications.
(2) Mg‑Zn‑Zr System Alloys
Cast magnesium alloys with zinc and zirconium as the main alloying elements. Typical grades include ZM1 (ZMgZn5Zr), ZM2 (ZMgZn4RE1Zr), and ZM7 (ZMgZn8AgZr). Mg‑Zn system alloys have a wide solidification range and are not suitable for pressure die casting, but they can achieve ideal mechanical properties through squeeze casting combined with aging treatment.
(3) Mg‑RE‑Zr System Alloys (Magnesium‑Rare Earth‑Zirconium)
Cast magnesium alloys with rare earth elements and zirconium as the main alloying elements. Typical grades include ZM3 (ZMgRE3ZnZr), ZM4 (ZMgRE3Zn2Zr), ZM6 (ZMgRE2ZnZr), as well as VW63K, VW83K, VW103K, WE54, WE43, and EA42. Mg‑RE system cast magnesium alloys can be formed not only by pressure die casting but also by sand casting, squeeze casting, and other processes. After T6 treatment, the yield strength can exceed 300 MPa and tensile strength exceed 400 MPa.
2.2 By Casting Process
Magnesium alloys have a wide adaptability to casting processes; almost all casting methods can be used to produce magnesium alloy castings. The main processes include:
- High‑Pressure Die Casting (HPDC) : The most mature and widely used casting technology for magnesium alloys. Magnesium alloys have low melting points and good fluidity, making them suitable for die casting and capable of producing thin‑walled components.
- Sand Casting: Suitable for large, complex‑shaped parts with good casting quality.
- Permanent Mold Casting (Gravity Die Casting) : Suitable for complex, large parts with good quality but higher cost.
- Investment Casting (Lost‑Wax) : High‑precision process for complex, precision castings.
- Low‑Pressure Casting: Suitable for medium‑sized, complex parts with good quality and relatively low cost.
- Squeeze Casting: Significantly reduces casting defects.
- Semi‑Solid Casting: An emerging casting technology.
2.3 By Designation Nomenclature
In the Chinese designation system, magnesium alloy grades consist of two Chinese pinyin letters followed by Arabic numerals: M stands for magnesium alloy, Z for casting, Y for die casting, and B for wrought. For example, ZM1 means No. 1 cast magnesium alloy, and YM5 means No. 5 die‑cast magnesium alloy. Internationally, most magnesium alloy grades follow the ASTM recommended nomenclature: two English letters indicate the main alloying elements (A‑aluminium, E‑rare earth, K‑zirconium, Z‑zinc, etc.), and the two subsequent digits indicate their nominal contents.
