What Is AZ31B Magnesium Alloy


AZ31B Magnesium Alloy is a commonly used magnesium alloy that belongs to the AZ (aluminum-zinc) series of alloys.

AZ31B Magnesium Alloy is composed of approximately 3% aluminum (Al) and 1% zinc (Zn) as the primary alloying elements, along with small amounts of other elements such as manganese (Mn) and copper (Cu). The “B” in AZ31B indicates a higher purity level of the alloy.

The Characteristics Chart Of AZ31B Magnesium Alloy


Here is a table outlining the general characteristics of AZ31B magnesium alloys:

Density (g/cm³)Tensile Strength (MPa)Yield Strength (MPa)Elastic Modulus (GPa)Melting Point (°C)
1.78240-310140-20045630
Composition:3% 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 AZ31B and AZ91D magnesium alloys.

The Properties Of AZ31B Magnesium Alloy


AZ31B magnesium alloy offers a good combination of mechanical properties, castability, and corrosion resistance, making it suitable for various applications. Here are some key properties of AZ31B:

1

Lightweight

Like other magnesium alloys, AZ31B has a low density, approximately 1.78 g/cm³, which is about two-thirds that of aluminum and one-fourth that of steel. This makes it an attractive choice for lightweight applications where weight reduction is important.
2

Strength

AZ31B exhibits moderate strength, providing good structural integrity in various applications. The tensile strength of AZ31B typically ranges from 240 MPa to 310 MPa, depending on the specific heat treatment and processing conditions.
3

Castability

AZ31B has excellent castability, allowing it to be easily cast into complex shapes using various casting methods, such as sand casting, permanent mold casting, or die casting. Its relatively low melting point (around 630°C) facilitates the casting process.
4

Corrosion Resistance

AZ31B alloy has good resistance to corrosion, particularly in dry or low-humidity environments. However, it can be susceptible to corrosion in humid or corrosive environments. Surface treatments or coatings can be applied to enhance the corrosion resistance of AZ31B components.
5

Damping Capacity

AZ31B exhibits good damping capacity, meaning 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

AZ31B can be machined using conventional machining processes, although its relatively low cutting forces and high thermal conductivity require specific cutting parameters and tooling considerations.

AZ31B magnesium alloy finds applications in various industries, including automotive, aerospace, electronics, and consumer goods. Common applications include automotive parts, such as body panels, chassis components, and powertrain parts, as well as components in electronic devices, sporting equipment, and lightweight structures.

It’s important to note that while AZ31B 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 processing conditions.
