Magnesium round bar is suitable for making extruded magnesium alloy profiles and can also be delivered directly. These Magnesium round bars are prized for their lightweight properties, making them ideal for applications in aerospace, automotive, and other industries where weight reduction is critical. In addition to being used for extrusion, magnesium round bars can be supplied directly in various sizes and lengths to meet specific design and manufacturing requirements. Their exceptional strength-to-weight ratio also makes them a preferred choice for parts that require both strength and reduced weight for improved performance.
As a professional company, YiRui Metal offers high-quality magnesium round bars that meet ASTM standards, ensuring expedited delivery times. However, it's important to note that only specific types of magnesium alloys can be produced as round bars. Unfortunately, alloys such as AM60B magnesium alloy and AM50A magnesium alloy are not included in this selection. For more details on the magnesium alloys available for round bar production, please refer to the chart below to find magnesium round bars that meet your custom needs.

Magnesium round bars are valued for their lightweight and durable properties, making them ideal for applications in the automotive, aerospace, and electronics industries. Below are key physical properties that make magnesium round bars highly effective in various uses:
Melting Point: Magnesium round bars have a relatively low melting point, making them suitable for die casting and molding processes. While this limits its use in extremely high-temperature applications, it works well for industries where high temperatures are not a primary concern.
Thermal Conductivity: With thermal conductivity, magnesium round bars excel in heat dissipation, making them ideal for use in heat-sensitive components such as electronics and heat exchangers.
Coefficient of Thermal Expansion: Magnesium round bars have a low coefficient of thermal expansion, providing dimensional stability across temperature fluctuations, which is especially important in precision industries like aerospace and automotive.
Magnetic Properties: Magnesium is non-magnetic, making it an excellent choice for applications in electronics and medical devices where magnetic interference must be avoided.
In summary, the physical properties of magnesium round bars—such as their low melting point, good thermal conductivity, stability under temperature changes, moderate electrical conductivity, and non-magnetic nature—make them ideal for a wide range of applications.
