Magnesium Ingot

Introduction of magnesium ingot
1. Definition and properties
Magnesium ingot is magnesium metal extracted from magnesium ore by electrolysis or thermal reduction, usually in the form of lumps or ingots. Its properties include:
Lightweight: magnesium is the lightest of the practical metals, with a density of 1.74 g/cm³, making it suitable for lightweight designs.
High specific strength: the mass ratio of strength to hardness is better than many metals, making it suitable for structural components.
Good cutting performance: easy to machine, suitable for complex shapes.
Excellent thermal and electrical conductivity: suitable for heat dissipation and conductive applications.
Corrosion resistance: performs well in dry environments, but requires surface protection in wet environments.

2. Manufacturing process
The manufacturing process of magnesium ingot mainly includes the following two methods:
Electrolysis method:
Extract magnesium chloride from dolomite or magnesite.
Electrolyze the molten magnesium chloride in the electrolyzer to obtain magnesium metal.
After refining, it is cast into ingots.
Thermal reduction method (Pijang method):
Dolomite is calcined and mixed with ferrosilicon reducing agent.
Reduction in a high temperature vacuum furnace to generate magnesium vapor.
After condensation, it is cast into ingots.

3. Areas of application
Magnesium ingots are widely used in the following industries:
Aerospace: Used in the manufacture of aircraft fuselage, engine parts and other lightweight structural parts.
Automobile industry: used in the manufacture of wheel hubs, transmission shells, seat skeletons and other components to reduce the weight of vehicles.
Electronics: used to manufacture lightweight and high strength parts such as laptop shells and cell phone frames.
Chemical industry: used in the manufacture of magnesium alloys, desulfurizers, reducing agents and so on.
Defense industry: used to manufacture ammunition, missile shells and other high-strength components.

4. Advantages
Light weight and high strength: significantly reduce the weight of products, while meeting the strength requirements.
Good processability: easy to cut, cast and mold.
Excellent thermal and electrical conductivity: suitable for heat dissipation and conductive scenes.
Environmentally friendly: magnesium can be recycled and utilized, in line with the concept of sustainable development.

5. Technical Challenges
Insufficient corrosion resistance: easy to corrode in humid environments, need to improve corrosion resistance through surface treatment (e.g. anodizing, coating).
Flammability: magnesium is flammable at high temperatures, and fire prevention measures need to be paid attention to when processing.

6. Market trend
With the growth of lightweight demand, the application of magnesium ingot in automotive, aerospace and electronics is expanding. At the same time, the progress of magnesium alloy technology and the popularization of the concept of environmental protection also promote the application of magnesium ingots in new energy and sustainable development.

7. Summary
With its light weight, high strength and excellent processing performance, magnesium ingot is widely used in many high-tech fields. In the future, with technological progress and the evolution of market demand, its application prospect will be even broader. Meanwhile, the competitiveness of magnesium ingots will be further enhanced by improving corrosion resistance and processing technology.
