Magnesium Alloy Supplier

Magnesium Alloy (Mg Alloy), fundamentally based on the light metal Magnesium (Mg) (Atomic Symbol), is the lightest metal alloy used for structural applications. Its defining property is its extremely low density, typically ranging from $1.74 to $1.81 g/cm3. This makes it approximately 1/4 the weight of steel and 2/3 that of aluminum, delivering superior mass reduction capabilities.

Magnesium alloys are formulated by adding elements like aluminum, Zinc, calcium, zirconium, and rare earths to enhance their overall performance.

In terms of mechanical properties, magnesium alloys exhibit outstanding specific strength.
For example: Cast alloys (such as AZ91D) can achieve tensile strengths up to 230 MPa with a density of approximately 1.8 g/cm³.
Wrought alloys (e.g., AZ31 extruded material) can achieve tensile strengths of 250 MPa or higher while maintaining good ductility.
High-temperature alloys (e.g., rare earth alloy WE43) maintain high strength at elevated temperatures, ranking among the strongest grades. They have a density of approximately 1.8g/cm³and a tensile strength reaching around 250 MPa.

Magnesium alloys are widely used in automotive (weight reduction), aerospace (high specific strength), laptop casings (lightweight and heat dissipation), and medical applications due to their lightweight properties, excellent vibration damping, good electromagnetic shielding performance, and high melting point of up to 650°C (pure magnesium). Magnesium alloys are ideal for achieving structural weight reduction and performance upgrades in these fields. aerospace (high strength-to-weight ratio), laptop casings (lightweight and heat dissipation), and medical applications. Magnesium alloys are an ideal solution for achieving structural weight reduction and performance upgrades.
