Feature
Application
1. Aerospace
Magnesium has long been used in the aerospace industry because of its low density and high specific strength. The aviation industry will take ways to increase the consumption of magnesium alloys.
2. Military field
Magnesium alloy has the advantages of light weight, good specific strength and stiffness, good vibration damping performance and strong shielding capability of electromagnetic interference, which can meet the requirements of military products for weight reduction, noise absorption, shock absorption and radiation protection.
3. Automobile field
The use of magnesium alloys as auto parts usually has the following advantages:
feature | advantage |
Improve comprehensive fuel economy standards | reduce exhaust emissions and fuel costs |
increase the loading capacity and payload of the vehicle | improve the braking and acceleration performance |
Light weight structure | improve the noise and vibration of vehicles |
4. 3C products
Nowadays, the most common 3C products using magnesium alloy are notebook computers. Driven by the development trend of 3C products towards light, thin, short and small direction, the application of magnesium alloy has been growing continuously in recent years.
5. Motorcycle field
Magnesium alloy applications components include power system, transmission system and a variety of motorcycle accessories more than 40 kinds.
So far, more than 60 parts of the automobile have been made of magnesium alloy. They are instrument panel base, seat frame, steering wheel shaft, engine valve cover, gearbox housing, intake manifold and automobile body.
