Aerospace
In the aerospace field, "gram by gram matters"—every 1 kg reduction in a rocket's weight can cut launch costs by $20,000, while reducing a missile's weight by 1 kg can extend its range by an impressive 15 km.
Magnesium alloys have the distinct advantage of being only two-thirds the density of aluminum and one-quarter the density of steel.
Aluminum-lithium alloy, as a lightweight yet high-strength metallic structural material, holds tremendous potential for applications in the aerospace industry. Adding just 1% lithium to aluminum alloy reduces its density by 3% while increasing its elastic modulus by 6%.
Replacing conventional aluminum alloys with aluminum-lithium alloys can reduce structural weight by 5% to 15% while increasing stiffness by 15% to 20%. The immediate weight-saving benefits enable a significant boost in the payload capacity of aerospace vehicles, offering substantial economic advantages and strategic importance.
Spacecraft Structure
The satellite's skeletal structure and solar panels utilize magnesium alloy thin-walled components, reducing the satellite's weight by 25% while ensuring structural stability through precision casting technology. Meanwhile, rocket engine components feature heat-resistant magnesium alloy nozzles fabricated using Directed Energy Deposition (DED) 3D printing, achieving a 30% weight reduction and improving high-temperature performance by 15%.
Aviation sector
In the area of lightweight aviation seating, the world's first magnesium alloy-based main structural component for aircraft seats has achieved a 22.8% reduction in weight, while maintaining strength comparable to aluminum alloys. Additionally, in terms of stealth upgrades for fighter jets, magnesium alloy electromagnetic shielding covers can attenuate up to 90% of electromagnetic interference, ensuring the stable operation of fighter jet radar systems even in complex electromagnetic environments.
Future Aerospace Technologies
The magnesium alloy thermal control system for reusable spacecraft leverages high thermal conductivity and thermal expansion compatibility with semiconductor materials, reducing temperature-control energy consumption by 40%. Meanwhile, the rare-earth magnesium alloy wings of hypersonic vehicles are fabricated using arc additive manufacturing, enabling complex hollow structures and increasing strength by 18%.
