Since the the successful design of the world’s first all-metal monoplane made of aluminum by German Hans Resnell in 1912 and the development of 2017 alloy, the the aviation industry has entered a period of rapid development.
In the past 100 years, the dominant position of aluminum alloy in aircraft body materials has not changed. Dozens of new aluminum alloys has been developed for the the continuous development of the aerospace industry, from the Al alloy 2024 and 7075 to 2124, 2224, 2324, 7050, 7010 those alloys. Others like aluminum-lithium alloys, rapid solidification aluminum alloys, aluminum-based composite materials has been under research.
Aluminum alloys are mainly used as structural materials in aircraft, such as body panels, frames, propellers, fuel tanks, and landing gear pillars. According to the different operating conditions and parts of the aircraft, three basic aluminum alloys are mainly used: high-strength aluminum alloy, heat-resistant aluminum alloy, and corrosion-resistant aluminum alloy.
High-strength aluminum alloy is mainly used for aircraft fuselage parts, engine compartments, seats, control systems, etc. Heat-resistant aluminum alloy parts are mainly used in the engine room close to the motor, air exchange system, etc. Corrosion-resistant aluminum alloy has sufficiently high strength, plasticity, impact toughness, fatigue performance, weldability and especially the corrosion resistance, so it can be used in seaplanes.
In China, the development and application of aviation aluminum alloy began in the 1950s, initially to meet the needs of aircraft maintenance and imitation. In the mid-1980s, we started developing 7075. 2024, 7475,etc. Since the 1990s, we have started our research on heat-resistant aluminum alloy and aluminum-lithium alloy.
At present, the top aircraft aluminum suppliers in China are Southwest Aluminum, Nannan Aluminum and Haomei Aluminum. Haomei Aluminum has been in this field for over 20 years, which can supply worldwide. Welcome to leave message below to inquire what you need.
