Product details
AZ31B magnesium alloy is a widely used deformed magnesium alloy, and Hot Rolled Magnesium Alloy Plate is a common product form in the materials processing field. However, when it comes to thicker magnesium plates, Casting Magnesium Alloy Plate and Forged Magnesium Alloy Plate are the key choices to meet this need. In the following section, we will provide a comprehensive analysis of their chemical composition and mechanical properties.
Chemical Composition of AZ31B Magnesium Alloy Sheet
Main alloying elements
Aluminium (Al): The mass fraction of aluminium in AZ31B magnesium alloys ranges from approximately 2.5% to 3.5%. Aluminium is a core element in the alloying system and significantly increases the strength and hardness of the alloy, giving it excellent mechanical properties. In addition, the right amount of aluminium optimises the casting properties and corrosion resistance of the alloy, making it perform better in the moulding process and in the real world.
Zinc (Zn): Zinc is present in AZ31B magnesium alloys at a mass fraction of approximately 0.7% - 1.3%. As an additional core element, Zinc produces a solid solution strengthening effect that, together with Aluminium, further strengthens the AZ31B Magnesium alloy and increases its load-bearing capacity.
Manganese (Mn): Manganese is typically found in AZ31B magnesium alloys in the range of 0.2% to 1.0% by mass. Within the alloy, Manganese is used to improve the corrosion resistance of the alloy by effectively neutralising impurity elements such as iron, thereby reducing the electrochemical corrosion caused by impurities and ensuring the stability and durability of the alloy in complex environments.
Impurity elements
Iron (Fe), copper (Cu) and nickel (Ni) are usually found at low levels in AZ31B magnesium alloys. These impurities not only reduce the corrosion resistance of the magnesium alloy, but also have a negative impact on the mechanical properties of the alloy, which can reduce the service life of AZ31B in practical applications.
Mechanical Properties of AZ31B Magnesium Alloy Plate
Tensile Strength: The tensile strength of AZ31B magnesium alloys is generally in the range of 220 - 290 MPa. However, this value can vary depending on a number of factors such as processing and heat treatment conditions.
Yield Strength: The yield strength of AZ31B magnesium alloys generally ranges from 140 - 200 MPa. Yield strength is a key indicator of the stress to which a material is subjected when it begins to deform plastically.
Elongation: AZ31B magnesium alloys typically have an elongation of 15% - 25%. This indicates that AZ31B magnesium alloys have some degree of plastic deformation and can be formed into a variety of shapes through a variety of processes such as rolling and extrusion.
Density Advantages of AZ31B Magnesium Sheet
The density of AZ31B magnesium alloy is approximately 1.78 g/cm³, whereas aluminium alloys typically have a density of 2.63 - 2.85 g/cm³. In areas such as aerospace, automotive and 3C electronics, where weight is critical, AZ31B magnesium alloys offer significant structural weight savings without compromising strength and performance. More critically, AZ31B magnesium alloy offers greater strength and stiffness than aluminium alloys for the same weight, allowing it to maintain structural stability and resist deformation or damage when subjected to greater external forces and loads.
AZ31B Magnesium Plate in Aerospace Applications
AZ31B magnesium alloy sheet has a wide range of important applications in the aerospace industry. On the one hand, it is used in the Magnesium Alloy Vibrating Platforms, providing critical data and practice for optimising the performance of aerospace equipment. On the other hand, AZ31B magnesium alloy plays an indispensable role in the manufacture of fuselages and wings. Due to its low density, the use of AZ31B magnesium alloy for fuselage components significantly reduces the overall weight of the aircraft, which in turn improves fuel efficiency and extends the range of the aircraft. At the same time, the alloy's strength and toughness ensure that the fuselage maintains its structural integrity and safety during flight.
