Successfully developed the largest magnesium-lithium alloy forging billet in China

Recently, Zhengzhou Qingyan Alloy Technology Co., Ltd. (China Metal Zhengzhou Nonferrous Metal Research Institute Metal Materials Research Institute) has continuously adjusted the vacuum melting casting process and deformation process to successfully prepare a large-size magnesium-lithium alloy 300kg forged billet with excellent performance, which effectively meets This has laid the foundation for the large-scale application of magnesium-lithium alloys on large-scale structural parts.

At present, China has listed the development of new practical magnesium alloys as the focus of future scientific and technological development and research. Especially in the past three years, magnesium-lithium alloy, as the metal structure material with the most potential for weight loss, has become more and more popular in areas where the demand for weight loss is extremely urgent in aerospace, defense military industry, high-end 3C electronic products, transportation, etc. From military aerospace satellites to civilian notebook computer cases, more and more cases have been successfully applied. However, due to the limitation of the domestic magnesium-lithium alloy casting level, the enterprises that can produce magnesium-lithium alloys are all castings and forgings of several tens of kilograms, and there are no large-scale magnesium-lithium alloy product parts available. The 300kg forging billet produced by Zhengzhou Qingyan Alloy effectively satisfies the needs of large and medium-sized components for the seamless structure of magnesium-lithium alloy, and realizes a major step in the localization, industrialization and scale-up of magnesium-lithium alloy.

Zhengzhou Qingyan Alloy Technology Co., Ltd., as the earliest enterprise in China to develop, produce, and sell magnesium-lithium alloys, built the first domestic magnesium-lithium alloy industrial production line in March 2010, devoted to magnesium-lithium alloy casting-alloying-pressure processing -Machining-Development and research of the whole process of heat treatment and surface treatment technology. It has accumulated a large number of proprietary technologies and has perfect process standards for melt casting, pressure processing, surface treatment and so on. The company's research and production capacity of magnesium-lithium alloys ranks first in the world. At present, the production of magnesium-lithium alloys accounts for more than 70% of the world's output and more than 95% of the national output.
