One of the future development direction of new materials
Technology wins the Future
In the age of technology, the future has arrived
In recent years, the thin and light this has become in recent years each big electric manufacturer advocate push a product. In addition to the thickness control of internal components, the volume and integration of components continue to improve, the choice of notebook shell material is also the main way to reduce the weight of the notebook, the current notebook commonly used shell materials for aluminum alloy, magnesium aluminum alloy and carbon fiber composite materials. With the continuous progress of The Times and the continuous development of materials, a new material magnesium lithium alloy, with a specific gravity of 1.48~1.52, came out, and there is a new choice for weight reduction.
What is magnesium lithium alloy LZ91?
Lithium is the lightest metal in the world (0.53 g/cm3)
Magnesium lithium alloy is the lightest commercial alloy material (1.48 g/cm3)
The Phase-rich (HCP) of the magnesium alloy is converted into a li-rich Phase-rich (BCC) structure by adding 10% lithium to the magnesium. Due to the addition of lithium in magnesium lithium alloy, the material has super light weight and excellent formability.
When magnesium lithium alloy was added, it had the lowest density among structural metal materials. Generally, lithium contained 14-16%, while its specific gravity was 1.48-1.52, lower than the 1.8 of ordinary magnesium alloy, slightly higher than the plastic, with strength of 220 ~ 340MPa and elastic modulus of 40GPa. Large damping, more than ten times that of aluminum alloy, that is, can absorb impact energy, damping and noise reduction effect is good, in shielding electromagnetic interference, magnesium lithium alloy also has outstanding performance.
Magnesium-lithium alloy weighs about a quarter as much as aluminum, but has a ceramic texture that makes it a good choice for making laptops.
More magnesium lithium alloy properties and advantages, ultralight and high strength material - magnesium lithium alloy in pen electric lightweight application prospect. In the initial stage of RD mechanism design, the r&d team of "Lvde Electronics" will participate in avoiding the limitations of materials, such as forming Angle, clamping structure, body thickness, assembly relationship, and reasonable distribution of strength supporting parts, so as to achieve structure forming.

Fujitsu Lifebook UH75/B1
In 2017, Fujitsu released A 13.3-inch notebook computer in Japan, the Fujitsu Lifebook UH75/B1, which weighs only 777G. The A part is forged from the magnesium lithium alloy LZ91/ LAz-Ares.
NEC LAVIE Hybrid ZERO
Following Fujitsu's introduction of the world's lightest 13.3-inch laptop, the new NEC LaVie Hybrid ZERO takes back the title of "world's lightest" with the launch of the 13.3-inch Fujitsu Lifebook UH75/B1. The 13.3-inch device weighs only 769g and is forged by LZ91.
