Magnesium AM50
Why Procurement Teams Upgrade to AM50:
Chasing raw rigidity on paper causes brittle cracks under dynamic stress. When safety is critical, you need a metal that flexes smoothly without splitting.
- Stop Brittle Failure: Balanced 4.5% aluminum blocks early cracking, letting high-impact parts bend safely.
- Absorb Heavy Shock: Elite ductility combined with steady yield limits handles sudden dynamic forces easily.
- Thin Wall Flow: Fluid melt fills massive complex dies perfectly, cutting foundry reject scrap waste.
Magnesium AM50 cast alloy is chiefly used in several components in the automobile sector. The following are some of them:
- Brackets
- Seat frames
- Steering wheels
- Instrument panels
- physical properties
- chemical composition
- mechanical properties
Here is the typical chemical composition of Magnesium AM50:
| Element | Content (wt%) | Notes |
| Magnesium (Mg) | Balance | Base metal |
| Aluminum (Al) | 4.0 – 5.0 | Primary alloying element |
| Manganese (Mn) | 0.2 min | Improves corrosion resistance |
| Zinc (Zn) | 0.3 max | Improves strength and corrosion resistance |
| Copper (Cu) | 0.05 max | Impurity limit |
| Iron (Fe) | 0.005 max | Impurity limit |
| Nickel (Ni) | 0.005 max | Impurity limit |
| Silicon (Si) | 0.02 max | Impurity limit |
Here are the typical mechanical properties of Magnesium AM50:
| roperty | Value | Unit | Notes |
| Ultimate Tensile Strength | 200 – 250 | MPa | Depends on processing and temper |
| Yield Strength | 120 – 150 | MPa | 0.2% offset |

How is magnesium alloy surface treated?
For the surface of magnesium alloy material is easy to deteriorate the problem, magnesium alloy products will be finalized after the final surface treatment, at present commonly used (phosphating, passivation), spraying, vacuum transfer printing, anodic oxidation, micro-arc oxidation and other treatment methods. Magnesium alloy micro-arc oxidation treatment is currently a common surface treatment in the rail transit industry. Our company has the capacity of micro-arc oxidation treatment of ultra-long profiles (>5 meters) and acid-resistant micro-arc oxidation treatment. Widely used in military, aerospace, machinery, electronics and rail transportation and other fields.
