Magnesium Alloy AZ91D Mechanical Properties

AZ91D is a magnesium alloy that is commonly used in various applications due to its desirable mechanical properties. Here are some of its mechanical properties:

  • Tensile Strength: magnesium alloy AZ91D has a tensile strength of 230 MPa (MegaPascals) in the as-cast condition, and it can be improved up to 270 MPa through appropriate heat treatment.

  • Yield Strength: The yield strength of magnesium alloy AZ91D is 140 MPa in the as-cast condition and can be improved up to 200 MPa with heat treatment.

  • Elastic Modulus: The elastic modulus of magnesium AZ91D is around 45 GPa (GigaPascals), which is lower than that of aluminum alloys and steel.

  • Ductility: AZ91D has good ductility, which means it can be easily formed into complex shapes. Its elongation at break is typically around 3-4%.

  • Fatigue Strength: The fatigue strength of magnesium alloy AZ91D is moderate compared to other engineering materials, and it decreases with increasing cyclic stress.

Overall, AZ91D is a lightweight material with good strength and ductility, making it an attractive choice for applications where weight reduction is important. However, it should be noted that magnesium alloys are prone to corrosion, so appropriate measures need to be taken to prevent corrosion in service.

AZ91D Magnesium Alloy Physical Properties

  • Density: The density of magnesium AZ91D is around 1.78 g/cm³, which is about one-third the density of steel and two-thirds the density of aluminum.

  • Melting Point: The melting point of magnesium alloy AZ91D is approximately 570°C (1060°F).

  • Thermal Conductivity: The thermal conductivity of magnesium alloy AZ91D is lower than that of aluminum alloys and steel, but higher than most plastics. It is around 75 W/mK (Watts per meter Kelvin) at room temperature.

  • Coefficient of Thermal Expansion: The coefficient of thermal expansion of magnesium alloy AZ91D is relatively high, around 26 x 10^-6/K (per Kelvin) in the temperature range of 20-100°C.

  • Electrical Conductivity: The electrical conductivity of magnesium AZ91D is relatively low, around 15% that of copper.

  • Magnetic Properties: magnesium AZ91D is not magnetic, which makes it suitable for applications where magnetic interference needs to be avoided.

Magnesium Alloy AZ91D Application

  • AZ91D magnesium alloy is a commonly used magnesium alloy in various industrial applications.  It is a cast alloy, which means it is formed by pouring molten metal into a mold and allowing it to solidify.

  • Magnesium in automotive industry: AZ91D magnesium alloy is commonly used in the automotive industry for components such as engine blocks, transmission cases, and wheels.  Its lightweight properties make it an attractive material for reducing the weight of vehicles, which can improve fuel efficiency and reduce emissions.

  • Magnesium alloy in aircraft: The alloy is also used in the aerospace industry for applications such as aircraft engine components, and in the electronics industry for housings and frames of devices like laptops and smartphones.

  • Other applications of AZ91D magnesium alloy include sporting goods such as golf club heads and bicycle frames, as well as medical implants and orthopedic devices due to its biocompatibility and strength-to-weight ratio.



AZ91D Magnesium Alloy Features

Magnesium alloy AZ91D is mainly cast by pressure die, which is characterized by high specific strength and greatly improved corrosion resistance compared with pure magnesium. This magnesium alloy for sale is mainly used for shells of electrical products, small-sized thin or special-shaped supports, etc.
The AZ91D alloy has a high strength-to-weight ratio, which makes it an ideal material for applications that require strength and durability while minimizing weight.  It has a density of 1.78 g/cm³, which is about two-thirds that of aluminum and one-fourth that of steel.
One of the key benefits of AZ91D is its excellent corrosion resistance, which is better than most other magnesium alloys.  This makes it a suitable material for use in harsh environments, such as marine or corrosive industrial settings.In addition, AZ91D Magnesium Alloy is easily machinable, allowing for the creation of complex shapes and parts with tight tolerances.  It can also be cast into a variety of shapes and sizes, making it a versatile material for a range of applications.
Overall, AZ91D Magnesium Alloy is a high-performance material that offers a unique combination of strength, durability, and light weight.  It is widely used in a variety of industries and is an excellent choice for applications where high strength and corrosion resistance are required.
