Good Thermal Conductivity Low Cutting Force Magnesium Round Bar For Aerospace Industry

The melting point of magnesium alloy is lower than that of aluminum alloy, and its die-casting performance is excellent. The tensile strength of magnesium alloy castings is comparable to that of aluminum alloy castings, generally reaching up to 250 MPa and, in some cases, exceeding 600 MPa. Yield strength and elongation are similar to those of aluminum alloy.

Magnesium alloy also offers good corrosion resistance, electromagnetic shielding performance, and radiation protection performance, and can be 100% recycled and reused.

Magnesium alloy parts exhibit high stability, and the casting line of die castings achieves high dimensional accuracy, allowing for high-precision processing. Magnesium alloy has good die-casting performance, and the minimum wall thickness of die-casting parts can reach 0.5 mm, making it suitable for manufacturing various die-casting parts for automobiles.

However, the linear expansion coefficient of magnesium alloy is relatively large, reaching 25–26 μm/m℃, compared with 23 μm/m℃ for aluminum alloy, approximately 20 μm/m℃ for brass, 12 μm/m℃ for structural steel, about 10 μm/m℃ for cast iron, only 5–9 μm/m℃ for rock (granite, marble, etc.), and 5–11 μm/m℃ for glass.

Compared with traditional magnesium alloy, semi-continuous casting delivers higher strength and extensibility in terms of 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 fewer impurities. This improves the compactness of the inner metallurgical structure of the magnesium rod, resulting in more reasonably dense internal crystallization. Physical properties are greatly enhanced compared with traditional casting products.
2. Impurities in the rhyolite tend toward 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 completely exposed to the air, which can only be flame-retarded by rhyolite and similar agents.
3. The surface is smooth and clean, with no porosity, no shrinkage, and no slag inclusion.
4. Length is flexible. The existing maximum diameter is Φ600 mm. Products can be peeled and cut as customized. We can also produce other specifications to meet customer requirements. Various specifications of magnesium alloy flat bar can be semi-continuously cast.

• Light weight: Magnesium is the lightest metal material in the world.
• High specific strength: Magnesium alloy has high strength-to-weight ratio and a certain bearing capacity.
• Small modulus of elasticity: Better strength and anti-seismic performance, not easily distorted.
• Good anti-electromagnetic interference and shielding.
• Non-polluting and recyclable.
• Stable dimensionally and easy to process.

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

Magnesium alloy casting production can be customized to your requirements. The technical process is excellent; extrusion production required for a variety of bars eliminates the need to purchase from abroad. Extrusion molding products are easy to mold with low energy consumption, saving production costs.

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