What Makes Magnesium Alloy Special?

Magnesium alloys are approximately 30% lighter than aluminum and significantly lighter than steel. Despite their low density, they still offer good mechanical strength and machinability.

Key advantages include:

• Extremely lightweight structure

• Good vibration damping performance

• Excellent machinability for CNC processing

• High strength-to-weight ratio

• Suitable for precision components

Common Grades of Magnesium Alloys

Different grades are used depending on the application requirements. Some of the most common include:

• AZ31B – widely used for sheet and plate applications

• AZ91D – commonly used in cast components

• ZK60 – used in high-strength structural parts

Each alloy offers a different balance of strength, ductility, and corrosion resistance.
