Introduction
Magnesium ingot is a metal magnesium ingot with a purity of ≥ 99.8%, which is silver white in color and is the most basic form of magnesium metal in industry. Magnesium is the eighth most abundant element in the Earth's crust (about 2.3%), lightweight (density 1.74 g/cm ³, only 2/3 of aluminum), strong, and easy to process, known as the "green engineering material of the 21st century".
Core advantages
Lightweight
It is 33% lighter than aluminum and 75% lighter than steel, making it an ideal material for weight reduction in fields such as automotive and aerospace.
high specific strength
The specific strength (strength/density) is superior to steel and aluminum, making it suitable for load-bearing structural components.
Excellent damping performance
Strong shock absorption ability, suitable for shock absorption components of precision instruments and transportation vehicles.
Good thermal and electrical conductivity
The heat dissipation performance is close to aluminum, used for electronic device heat dissipation components.
Strong recyclability
100% recyclable, in line with environmental trends.
Excellent processing performance
Easy to cast, forge, and cut, suitable for the production of complex parts.
Electromagnetic shielding
Block electromagnetic waves, used for electronic device casings.
Application Area
automotive industry
Usage: Engine bracket, wheel hub, gearbox housing, etc.
Advantages: Reduce weight by 10% to 30%, lower fuel consumption and emissions (such as some Tesla models using magnesium alloy chassis).
EADS
Usage: Aircraft seats, cabin door frames, missile components.
Advantages: Lightweight design improves fuel efficiency, and the Boeing 787's fuselage is made of magnesium alloy.
3C Electronics
Usage: Laptop case, phone frame, camera body.
Advantages: heat dissipation+electromagnetic shielding+lightweight (such as ultra-thin magnesium alloy laptops weighing only 800g).
Military equipment
Usage: Armored vehicle components, drone frames, individual soldier equipment.
Advantages: Lightweight design enhances maneuverability, with some parts of the American Hummer military vehicles made of magnesium alloy.
Medical field
Usage: Orthopedic implants (such as degradable magnesium alloy bone nails).
Advantages: Biocompatibility+natural degradation, avoiding secondary surgery.
Chemical Industry and Energy Storage
Usage: Magnesium based hydrogen storage material, negative electrode of batteries (such as magnesium sulfur batteries).
Advantages: High hydrogen storage density (7.6wt%), making it a potential substitute for lithium-ion batteries.
Other industries
Metallurgy: Aluminum alloy additives (to enhance strength).
Fireworks: Magnesium powder is used to manufacture lighting flares and fireworks.
Market Prospect
Demand growth: The global magnesium ingot market is expected to exceed $6 billion by 2025, with an annual growth rate of approximately 7% (driven by the new energy vehicle and electronics industries).
Technological breakthrough: The improvement of corrosion resistance (such as surface treatment technology) will further expand its application scenarios.
