What Is AZ91D Magnesium Alloy


AZ91D Magnesium Alloy is a widely used magnesium alloy that belongs to the AZ (aluminum-zinc) series of alloys.

AZ91D Magnesium Alloy is composed of approximately 9% aluminum (Al) and 1% zinc (Zn) as the primary alloying elements, along with small amounts of other elements such as manganese (Mn), silicon (Si), and copper (Cu). The “D” in AZ91D refers to the high purity level of the alloy.

The Characteristics Chart Of AZ91D Magnesium Alloy


Here is a table outlining the general characteristics of AZ91D magnesium alloy:

Density (g/cm³)Tensile Strength (MPa)Yield Strength (MPa)Elastic Modulus (GPa)Melting Point (°C)
1.8240-310140-20045535
Composition:9% Al, 1% Zn, balance Mg

Please note that these values are approximate and can vary depending on specific manufacturing processes, heat treatments, and testing methods.

It is important to refer to detailed technical data sheets or material specifications provided by manufacturers for precise information on the characteristics and properties of AZ91D magnesium alloy.

The Properties Of AZ91D Magnesium Alloy


AZ91D magnesium alloy offers a good balance of mechanical properties, castability, and corrosion resistance, making it suitable for various applications. Here are some key properties of AZ91D:

1

Lightweight

Like other magnesium alloys, AZ91D has a low density, about 1.8 g/cm³, which is approximately one-fourth that of steel and two-thirds that of aluminum. This makes it an attractive choice for lightweight applications, where weight reduction is a critical factor.
2

Strength

AZ91D exhibits moderate to high strength, providing good structural integrity in various applications. The tensile strength of AZ91D typically ranges from 240 MPa to 310 MPa, depending on the specific heat treatment and processing conditions.
3

Castability

AZ91D has excellent castability, meaning it can be easily cast into complex shapes using various casting methods, such as sand casting, permanent mold casting, or die casting. Its low melting point (around 535°C) facilitates the casting process.
4

Corrosion Resistance

AZ91D alloy has relatively good resistance to corrosion compared to pure magnesium. However, it is still susceptible to corrosion in humid or corrosive environments. Surface treatments or coatings are often applied to enhance the corrosion resistance of AZ91D components.
5

Damping Capacity

AZ91D exhibits good damping capacity, which means it can effectively absorb and dissipate vibrations and reduce noise. This property makes it suitable for applications that require vibration damping, such as in automotive components or electronic devices.
6

Machinability

AZ91D can be machined using conventional machining processes, although its relatively low cutting forces and high thermal conductivity require specific cutting parameters and tooling considerations.

AZ91D magnesium alloy finds applications in various industries, including automotive, aerospace, electronics, and consumer goods. Common applications include automotive parts, such as transmission cases, engine blocks, and wheels, as well as components in electronic devices, sporting equipment, and lightweight structures.

It’s important to note that while AZ91D offers several advantages, it also has limitations. For example, it has lower creep resistance compared to some other magnesium alloys, and its mechanical properties can be affected by factors such as grain size, temperature, and casting process parameters.
