China Special aluminum alloy manufacturer and Supplier for Aerospace Aluminum Alloy materials

From Tiangong 2 to Shenzhou 11 to Long March 5, on the 60th anniversary of China `s aerospace this year, a series of aerospace feats have inspired and pride the Chinese people. At 20:43 on November 3, the landmark China's newly developed large-thrust carrier rocket "Long March V" was launched at the Wenchang launch site in Hainan. After 30 minutes, the load assembly was successfully separated from the rocket and arrived at the scheduled date. Orbit, launch was a complete success.

DQ Company is the earliest enterprise involved in the development of aluminum alloy materials in China's aerospace industry. Since October 8, 1956, China's first rocket and missile research institute was established, marking that China's space industry has entered the stage of history. In the past 60 years of China Aerospace, DQ has established hundreds of scientific research projects in aerospace. In the past ten years, nearly 10 large-scale scientific research achievements have come out. DQ aluminum alloys have been accompanying the development of the aerospace industry all the way, and have always been committed to the dream of a space power.

Over the years, hundreds of researchers and thousands of engineers and technicians from DQ Group have fought in the front line of scientific research, overcome numerous technical problems, and after hard research and unremitting efforts, they have successfully developed high-performance aluminum alloy materials for aerospace. Fill the gap in our country. After the successful launch of the rocket, DQ became the designated manufacturer of aluminum alloy materials for the Long March series of launch vehicles. The aluminum alloy materials with independent intellectual property rights were identified as the final products for the Long March series of launch vehicles.

It is understood that a large number of aluminum alloy materials are required for the Long March series of launch vehicle propulsion modules, fuel tanks and other structures. In addition to key products that require process research and quality research, this type of material requires absolute stability and reliability, and stability and reliability are very demanding, that is, uniform organization and stable performance, requires process flow and parameter curing, and quality assurance requirements are foolproof. After years of technical research, DQCompany has achieved a number of major scientific research results. It has provided a large number of high-strength, high-toughness, and high-corrosion-resistant aluminum alloy materials for the Long March series of launch vehicles, mainly including aluminum alloy plates, profiles, rods, wires, and Forgings and other products are mainly used in key parts such as skins, stiffeners, structural parts, ignition devices and load-bearing components of launch vehicles. 

The successful launch of the Long March V launch vehicle is a one-time large-scale low-temperature liquid bundling launch vehicle developed in 2006, and it is also a new generation of China's new-generation carrier rocket with a core core diameter of 5 meters. It will be applied to the construction of China's future Tiangong space station, Beidou navigation system, the third phase of the moon exploration project and other deep space exploration. The rocket series has stricter requirements on the properties and specifications of aluminum alloy materials, especially the comprehensive performance such as strength and corrosion resistance is almost harsh. In order to ensure the stability and reliability of the quality of these highly comprehensive performance materials, during the development and production process, DQ Company has made every effort to overcome the high technical requirements for the actual situation of large-scale investment in aerospace products, complex specifications, many varieties, and low usage. Difficulties such as production discontinuities and high cost control pressures have specifically opened up green channels. From melting and casting to rolling, from heat treatment to internal tissue inspection, from extrusion to forging, each process and process is full of cutting-edge challenges. The process parameters are extremely strict. Quality checks and test adjustments have ensured the absolute reliability of each process parameter and each batch of products. We have repeatedly submitted qualified answers to the aerospace industry in China. In order to meet the needs of aerospace.

In recent years, with the strong support of Chinalco, DQ Company has launched a technological transformation project of oversized 4 billion yuan special aluminum alloy strips. Today, this project is The development of the aviation industry plays an irreplaceable role. This major project is to help the aerospace industry grow its wings.
