What Is Magnesium And Alloy

Magnesium alloys are metal alloys composed primarily of magnesium along with other elements. These alloys are created by combining magnesium with various alloying elements, such as aluminum, zinc, manganese, and rare earth metals. Magnesium alloys are the lightest structural metals with a high strength-to-weight ratio.The addition of these elements imparts specific properties and characteristics to the magnesium, enhancing its strength, corrosion resistance, and other desirable qualities.

Corrosion and mechanical properties have many characteristics: fast heat dissipation, light weight, good rigidity, certain corrosion resistance and dimensional stability, impact resistance, wear resistance, good attenuation performance and easy recycling; in addition, it also has thermal conductivity and High conductivity, non-magnetic, good shielding, non-toxic and so on.

How Hard Is It To Machining Magnesium Alloy?

While magnesium provides many benefits, it is also a difficult alloy to machine.Machining Magnesium alloy can present certain challenges compared to other materials. While it is not necessarily extremely difficult, it requires specific considerations due to the properties of magnesium and its alloys. Here are some factors that make machining magnesium unique:



Magnesium is highly flammable and can ignite at relatively low temperatures. When machining magnesium, the heat generated by cutting and friction poses a fire risk. Special precautions, such as using proper machining techniques, coolant selection, and fire suppression systems, must be taken to mitigate this risk.

Heat Dissipation

Magnesium has a relatively high thermal conductivity, meaning it can conduct and retain heat more effectively than some other materials. This can lead to heat build-up during machining, which may affect tool life and dimensional accuracy. Proper cooling and chip evacuation methods are essential to manage heat dissipation.

Low Cutting Forces

Magnesium alloys are generally softer and have lower strength compared to other metals. This characteristic results in lower cutting forces during machining. While this can be advantageous in terms of reduced tool wear, it may require adjustments in cutting parameters and tool selection to prevent excessive material deformation or chatter.

Chip Control

Magnesium alloys tend to produce long, continuous chips during machining. These chips can be flammable and pose a safety hazard. Effective chip evacuation systems, such as chip breakers or chip conveyors, should be employed to control chip formation and minimize the risk of chip accumulation.

Tool Selection

Appropriate cutting tools are crucial for machining magnesium. Carbide tools are commonly used due to their high heat resistance, hardness, and wear resistance. Coatings like titanium nitride (TiN) or aluminum titanium nitride (AlTiN) can enhance tool life and performance. Additionally, tools with sharp cutting edges and polished surfaces help reduce heat and improve chip control.

Corrosion Concerns

Magnesium alloys are prone to corrosion, especially when exposed to moisture or certain environments. It is important to consider post-machining processes, such as surface treatments or coatings, to protect the machined magnesium components from corrosion.

Machining magnusium alloy materials involves selecting the right equipment, with the right partner who can customize, deploy and support your manufacturing and purchasing strategies. With BE-CU, you’ll not only get one-stop metal cnc machining service and you’ll receive the support and solve all your doubts about machining & production.
