Product Description
AZ91D Magnesium Alloy Sheet
Product Overview
AZ91D magnesium alloy sheet from Huona is a high-strength, cast-derived magnesium alloy optimized for die-cast-like mechanical performance in rolled sheet form. Featuring a higher aluminum content (9% Al, 1% Zn) than AZ31B/AZ61A, this grade delivers exceptional hardness, yield strength, and castability, making it ideal for high-load structural components, automotive powertrain parts, and consumer electronics housings. Manufactured via precision hot rolling and T4 solution heat treatment, it offers uniform grain refinement, consistent mechanical properties, and a smooth mill finish, balancing lightweight design with industrial-grade durability.

Key Differentiating Advantages
1. Industry-Leading Strength & Hardness
AZ91D offers a 15–20% increase in yield strength compared to AZ61A, making it the strongest common magnesium sheet alloy for structural applications. Its fine-grained microstructure delivers exceptional hardness and resistance to deformation under static and dynamic loads, ideal for high-stress components.
2. Cast-Like Performance in Rolled Form
Unlike traditional cast AZ91D, this rolled sheet eliminates porosity and shrinkage defects, offering uniform mechanical properties across the entire plate. It combines the alloy’s inherent castability with the precision and consistency of rolled materials, enabling complex machined parts without casting limitations.
3. Superior Corrosion Resistance for Magnesium
The controlled low-impurity composition (strict limits on Fe, Ni, Cu) minimizes galvanic corrosion risks, while the high aluminum content forms a dense, stable oxide layer. AZ91D exhibits better atmospheric corrosion resistance than AZ31B/AZ61A, even without surface treatment, making it suitable for semi-exposed industrial environments.
4. Optimized Machinability for High-Volume Production
Despite its high strength, AZ91D maintains excellent CNC machinability, with reduced tool chatter and chip formation issues compared to harder alloys. Its uniform grain structure enables precision milling, drilling, and tapping for complex components, supporting high-volume manufacturing with tight tolerances.
5. Balanced Thermal & Electrical Properties
The alloy’s thermal conductivity (~72 W/m·K) is lower than pure aluminum but sufficient for moderate heat dissipation applications, while its electrical resistivity (~12 μΩ·cm) supports lightweight grounding and shielding solutions in electronics.
