What is magnesium alloy semi-solid die casting?

Semi-solid die-casting uses the principle of semi-solid slurry shear thinning to subject it to shear stress field during the filling process to improve the filling capacity and obtain perfect casting surface quality. Characteristics of magnesium alloy semi-solid die casting:

①Light weight：

The density of magnesium alloy is 1.83, which is 2/3 of aluminum and 1/4 of iron. It is the lightest metal among practical metals. It is mainly used in electronic products and is used in various lightweight products. Lightweight products can save energy and reduce carbon dioxide emissions;

②Excellent strength：

Magnesium alloy and plastic items have a larger specific gravity than plastic, but it has stronger bending elasticity and tensile strength, and can be molded into thin-walled products. For the same strength requirements, it can be molded into lightweight products;

③Good heat dissipation：
Magnesium alloy has good heat transfer characteristics, with a thermal conductivity of 150W/mk, which can effectively dissipate the internal heat of the machine;

④Good electromagnetic：
wave shielding In the domestic and foreign markets, many digital products are prone to emit electromagnetic clutter, so these products must control the clutter within the specified range of electromagnetic waves. Magnesium alloys have high electromagnetic wave shielding performance;

⑤Regeneration：
Magnesium alloy is a metal, and it is easier to remelt. It can be regenerated into raw materials. The energy of magnesium alloy used in regeneration is only 4% of the production of new raw materials. Increase the utilization rate of recycled materials, and magnesium alloy will become an economical and practical material that optimizes the environment;

⑥Vibration damping：
Magnesium alloy has vibration damping properties, and the use of magnesium alloy can reduce noise and extend the service life of various devices;

⑦Dimensional stability：
With the passage of temperature and time, the size of magnesium alloy products hardly changes, and the original size of the product is maintained for a long time;

⑧ Impact resistance：
Because magnesium alloy has high impact resistance, it is not easy to dent and deform due to impact;

⑨Machining performance：
Magnesium alloys are easy to process, which can greatly save processing time and processing costs;

⑩Rich resources：
The seawater contains 0.13% magnesium, and the ore also contains a large amount of magnesium. my country is the country with the largest reserves of magnesium ore in the world

Advantages of magnesium alloy semi-solid die casting:

①Easy to replace: Since magnesium alloy scraps are used as raw materials, no melting furnace is needed, so it is easy to replace the type of magnesium alloy formed;

②Excellent quality: Due to the fast injection speed and high injection pressure, the product surface quality is excellent, and thin-walled products with high precision can be formed;

③Good size and mechanical properties: Compared with ordinary die-casting, the melting temperature of magnesium alloy is lower, and the forming dimensional accuracy and mechanical properties are good

④Good compactness: Since the magnesium alloy put into the molding machine is not in contact with air, the operating environment, safety and cleanliness are better than ordinary die-casting;

⑤Environmental protection: without SF6 protective gas, it is an excellent process for protecting the earth's environment;
