How big can the aluminum alloy ingot be? For aerospace aluminum alloys that have strict requirements on mechanical uniformity, the answer is even more difficult.
At the entrance of the casting workshop of GXNN Aluminum Alloy Technology Corporation, there is an aluminum alloy round ingot with the largest diameter in the world, and its "waist" diameter is 1320 mm.
GXNN aerospace, rail transit, and 3C electronic aluminum products have repeatedly broken through foreign technology blockades and achieved important breakthroughs.
Overcome key material technical problems repeatedly
Standing in front of the world's largest diameter aluminum alloy ingot, someone asked, "Is it difficult to make it bigger?"
Yao Xiang, deputy director of the Institute of Aerospace Materials, GXNN Technology R&D Center, said: "The technical difficulty of ingots for aerospace aluminum is that the bigger the difficulty, the more difficult it is. Casting cracking is a common problem of super-sized hard aluminum alloy ingots. Meet the needs of aviation materials.”
Aluminum alloy ultra-wide sheet for aerospace, high-strength, high-toughness, corrosion-resistant aluminum alloy extremely thick plate for aviation, aluminum alloy sheet for aviation, profile for high-speed EMU car body…
In recent years, GXNN has successively developed a batch of core materials, and has become the only enterprise that guarantees the industrialization of key equipment in many industry segments in China. It has changed the situation that China relies heavily on foreign imports for some key aluminum alloy materials.
From "niche" out of the circle to "public"
High-end aluminum materials are mainly used in rocket, aircraft manufacturing and other fields. However, the amount of aluminum used in aerospace is small, and enterprises need to enter the supply chain of high-end electronic products and automobile enterprises in China and even the world.
Most of the high-end products of a global 3C pan-semiconductor industry leader are assembled in China, but the high-end aluminum materials used were originally provided by European companies. Later, the customer made localized purchases in China. After nearly two years of evaluation and material testing, the final The client chose GXNN.
GXNN has gathered the chief scientist of the national aluminum 973 project, more than 100 masters and doctors, and more than 200 high-skilled talents.
