Magnesium AZ61A
Why Structural Engineers Specify AZ61A:
Stop guessing if your extrusions will hold the load. AZ61A brings a balanced, high-strength profile that performs under consistent mechanical stress.
- Elite Load Bearing: The 6% aluminum content offers a robust yield limit, preventing structural sagging.
- Weldability First: Optimized chemistry ensures clean, crack-free joints for complex frame assemblies.
- Precision Extrusion: Smooth grain structure flows through complex dies, ensuring tight dimensional tolerances.
AZ61A is highly regarded for its weldability. By maintaining strict control over the manganese-to-iron ratio (keeping iron below 0.005%), we ensure that the heat-affected zone during welding remains strong and corrosion-resistant.

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.
