Industry Thermally Conductive Magnesium Alloy Bar Excellent Machining Performance

Magnesium alloys are the third largest metal engineering material after steel and aluminum, widely recognized as the green engineering material of the 21st century. Magnesium alloy profiles are primarily used across the chemical, electronics, transportation, and aerospace industries. The most common magnesium alloy grade is AZ31B.

Our thermally conductive magnesium alloy bars deliver excellent machining performance and are engineered for demanding industrial applications.

Magnesium is the lightest of all practical metals, with a density approximately two-thirds that of aluminum and one-quarter that of iron. It offers high strength and high rigidity. Magnesium alloys are widely used in portable equipment and the automotive industry to achieve weight reduction.

Although heavier than plastic, magnesium alloy offers higher strength and elastic modulus per unit weight. For parts of equal strength, magnesium alloy components are thinner and lighter than plastic equivalents. Since the specific strength of magnesium alloy also exceeds that of aluminum alloy and iron, the weight of aluminum or iron parts can be reduced without compromising strength. Magnesium alloys are commonly used for support frames and back shells of LCD screens on mobile phones and notebook computers.

While the thermal conductivity of magnesium alloy bars is lower than that of aluminum alloys, it is dozens of times higher than that of plastics. This makes magnesium alloys effective at transferring internal heat to the exterior in electrical products. Typical applications include casings and heat dissipation components for high-temperature computers and projectors. Magnesium alloy can be used on TV casings without the need for heat dissipation holes.

The electromagnetic wave shielding performance of magnesium alloy bars exceeds that of electroplated shielding films on plastics. Using magnesium alloy eliminates the need for the electroplating process required for electromagnetic wave shielding films. Common applications include mobile phone casings and shielding materials.

Magnesium alloy bars offer lower cutting resistance than other metals, enabling faster processing speeds. Available alloy families include:

• Magnesium-aluminum-zinc alloys: AZ31B, AZ40M, AZ61M, AZ91D, etc.
• Magnesium-manganese alloys: M2M, etc.
• Magnesium-zinc-zirconium alloys: ZK61M, ZK61S, etc.

Compared with traditional magnesium alloy production, semi-continuous casting delivers higher strength and greater extensibility in both structure and composition.

1. Magnesium liquid is poured directly from the holding furnace and rapidly crystallized through pipetting and double refining with high purity and minimal impurity content. This improves the compactness of the inner metallurgical structure of the magnesium rod, resulting in more uniform internal densification and crystallization. Physical properties are significantly enhanced compared to traditional casting products.
2. Impurities in the rhyolite are reduced to near zero in the molded product. Semi-continuous casting magnesium alloy adopts a new inert gas protection device, greatly reducing entrapped slag and improving product quality. In the traditional process, the smelting process is fully exposed to air, which can only be protected by rhyolite and similar methods.
3. The surface is smooth and clean, free from porosity, shrinkage, and slag inclusion.
4. Length is flexible. The existing maximum diameter is Φ600mm. Products can be peeled and cut to customized specifications. We also produce other specification products to meet customer requirements. Various specifications of magnesium alloy flat bar can be semi-continuously cast.

• Lightweight: Magnesium is the lightest metal material in the world.
• High specific strength: Magnesium alloy offers high strength and quality with reliable bearing capacity.
• Small modulus of elasticity: Provides better strength, anti-seismic performance, and resistance to distortion.
• Excellent electromagnetic interference shielding.
• Non-polluting and recyclable.
• Dimensionally stable and easy to process.

We operate advanced die-casting, extrusion, forging, rolling, and casting processing production lines alongside precision testing equipment. We can produce a wide variety of magnesium alloy types and products, and have developed high-strength magnesium alloy extruded sheet. Through the purification of ordinary magnesium, we can raise magnesium purity up to 99.99%.

Magnesium alloy casting production can be customized to your requirements. Our technical process is highly refined, and extrusion production for a variety of bars requires no overseas procurement. Extrusion molding products are easy to form, consume low energy, and reduce production costs.

Our team includes magnesium smelting technology personnel with more than 15 years of experience. From the selection of primary materials to smelting processing, we bring a wealth of experience and mature management techniques. We maintain technical research and development capabilities in magnesium ingots and magnesium alloy extrusion products, placing us at the forefront of magnesium alloy production enterprises.
