Selecting the right manufacturing process requires balancing weight, structural integrity, and production reliability. While traditional Magnesium and Aluminium (ADC12) die casting has long been an industry standard, it often struggles with gas porosity, internal defects, and component warpage.
Explore the comprehensive mechanical, thermal, and physical data below to see how Thixomolding outperforms
conventional casting methods.
| Property | Magnesium Thixomolding (AZ91D) | Magnesium Die Casting (AZ91D) | Aluminium Die Casting (ADC12) |
|---|---|---|---|
| Density (g/cm³) | 1.81 | 1.81 | 2.70 |
| Tensile Strength (MPa) | 260 | 215 | 255 |
| Yield Strength (MPa) | 150 | 140 | 155 |
| Elastic Modulus (GPa) | 45 | 45 | 71 |
| Elongation (%) | 8 | 3 | 2 |
| Thermal Conductivity (W/m·K) | 72 | 72 | 96 |
| EMI Shielding @ 100 MHz (dB) | 75 | 75 | 85 |
| Vibration Damping (loss factor η) | 0.025 | 0.015 | 0.0005 |
| Electrical Conductivity (MS/m) | 6.7 | 6.7 | 14 |
| Corrosion (mg/cm²/day, uncoated, 3.5% NaCl) | 5 | 8 | 0.3 |
| Strength-to-Weight Ratio (MPa·cm³/g) | 143 | 119 | 94 |
| Porosity (%) | 0.5 | 3 | 2 |
| Shock Absorption | Very High | High | Low |
| Hardness (HB) | 73 | 68 | 80 |
| ~33% lighter | than ADC12 aluminium at comparable strength — ideal for EV range, fuel efficiency, and structural weight reduction. |
| 50% higher strength-to-weight | ratio than ADC12 (143 vs. 94 MPa·cm³/g) — best in class for load-bearing lightweight parts. |
| 50× better vibration damping | than aluminium — superior NVH performance for transmission cases, brackets, and housings. |
| Lower porosity (<1%) | than either die-casting process — ideal for pressure-tight, thin-wall, and structural parts. |
| Comparable EMI shielding | to aluminium at significantly lower weight — perfect for electronics and infotainment housings. |
| SF6-free, recyclable | eco-friendly process with up to 90% yield and 100% recyclable magnesium chips as raw material. |
