AZ80 Magnesium Alloy

AZ80 is a relatively high-strength wrought magnesium-aluminum-zinc alloy offering a good strength-to-weight ratio, good machinability, and heat-treatable properties. Compared with AZ31B, AZ80 provides higher strength and hardness, making it better suited for lightweight mechanical components subjected to higher loads.

Appearance & Properties

Color: Silver-white to light gray

Density: Approx. 1.80 g/cm³

Tensile Strength: Approx. 300–380 MPa, depending on condition and heat treatment

Corrosion Resistance: Moderate

Machinability: Good

Weldability: Moderate

Strength: Relatively high

Heat Treatment: Can be age-hardened for improved properties

Surface Finishes: Chemical conversion coating, anodizing, bead blasting, painting, powder coating, etc.

Typical Applications

AZ80 is widely used in aerospace, automotive, motorcycles, industrial equipment, sporting goods, and high-performance lightweight structures.

Typical parts include wheels, brackets, connectors, robotic components, structural frames, transmission parts, and high-strength precision CNC components.

Advantages

• Higher strength than AZ31B

• Good strength-to-weight ratio

• Good CNC machinability

• Mechanical properties can be improved through heat treatment

• Suitable for medium-to-high load lightweight components

Limitations

• Limited corrosion resistance

• Lower weldability than AZ31B

• Generally more expensive than common magnesium alloys

• Not ideal for prolonged high-temperature service
