CTOnews.com April 3 news, According to Lenovo official news, Recently, Lenovo Group and China Aluminum Ruimin jointly developed "Silk Aluminum" 5L52 passed the national standard examination and approval, Become a new national standard brand, And on March 28, Held an unveiling ceremony in Beijing. Lenovo said that 8 million notebook products will use "silk aluminum" 5L52 material this year.

Lenovo "Silk Aluminum"5L52 was awarded the new national standard registration certificate Recently, the new aluminum material "Silk Aluminum"5L52 developed by Lenovo Group officially passed the national standard review and promulgated, and was compiled into the national standard GB / T 3190. This brand is the first new national standard for Chinese original aluminum alloy plate and strip in the 3C field. According to introduction, the notebook computer products using this "silk aluminum" material have beautiful color, silky light feeling, delicate surface unique high-end texture.

"Silk Aluminum" 5L52 gives consideration to metallic luster and silky feel. According to CTOnews.com, Lenovo just officially released the spring new products of the full series of small new notebooks in 2023 last month. Among the new laptop products, the slim, stylish new Air 14 2023 haze purple color is refreshing. The laptop body adopts Lenovo's self-developed aluminum "silk aluminum," which has silky feel and luster, face value and experience. According to officials,"silk aluminum" materials have been widely used in YOGA, Xiaoxin, Savior, ThinkBook and other Lenovo product series.

Lenovo Xiaoxin Air 14 2023 haze purple in recent years to benefit from the pursuit of notebook computer design extreme thin, magnesium aluminum alloy material heat greatly increased. Before the birth of "silk aluminum" material, most of the aluminum-magnesium alloy plate brands in GB / T 3190 followed the material numbers of the former Soviet Union, the United States and Japan, and have been used for decades.

Lenovo officials said that starting from 2020, Lenovo's consumer notebook R & D team quantified the "perceptual cognition" of face value and quality by scientific means and believed that the plates used in the industry at that time could not meet the needs of users for the beauty and quality of computers. During the three years of research and development, Lenovo and many core partners in the organization industry chain completed the standardization and digitization of the whole process together, overcame technical problems one by one, and made tens of thousands of samples. Finally, a brand-new material "Silk Aluminum"5L52 named after the initial letter "L" in Lenovo LENOVO was created.

In the process of manufacturing "Silk Aluminum" 5L52 material, strict control of iron content is realized, the temperature range of annealing tempering is clearly defined, and the most reasonable grain size control is carried out in the face of the changes of grain growth, displacement and dislocation during rolling, so as to make the interface between each grain the most uniform and the dislocation generated the least. In the process of anodic oxidation, each component that produces acid corrosion is accurately controlled, including temperature, time, and particle, speed, area and angle of sand blasting, and a number of key process technology indicators are solved and finalized.

"Silk Aluminum" 5L52 has uniform metallographic structure With Lenovo Xiaoxin product launch conference, named "Silk Aluminum" 5L52 officially launched to users, Lenovo is expected to have 8 million Lenovo notebook products this year using "Silk Aluminum" 5L52 material.
