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.
