Extruded Magnesium Alloy Rod Slab Bar AZ31B AZ61 AZ91 For Bicycle Tube Wheelchairs

Extruded magnesium alloy rod, slab, and bar in grades AZ31B, AZ61, and AZ91 are engineered for demanding applications such as bicycle tubes and wheelchair frames. Semi-continuous casting bar is widely used in the processing of magnesium alloy plate, sheet, rod, and bar, and is also suitable for alloy ingots and other board products.

Compared with traditional magnesium alloy, 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 low impurity content. This improves the compactness of the inner metallurgical structure of the magnesium rod, producing a more uniform and denser internal crystallization. Physical properties are greatly enhanced compared with traditional casting products.
2. Impurities in the melt 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 and can only be protected against burning by agents such as rhyolite.
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 to customized dimensions. We can also produce other specifications to meet customer requirements, and 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 offers high strength-to-weight ratio and a certain load-bearing capacity.
• Small modulus of elasticity: Provides better strength, anti-seismic performance, and resistance to distortion.
• Good anti-electromagnetic interference and 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 magnesium alloy products, and have developed high-strength magnesium alloy extruded sheet. Through the purification of ordinary magnesium, purity can be raised to 99.99% high purity.

Magnesium alloy casting production can be customized to your requirements. The technical process is robust, and extrusion production covers a variety of bars without the need to purchase from abroad. Extrusion molding products are easy to form, consume low energy, and help save 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, and stand among the leading magnesium alloy production enterprises.
