What is aviation aluminum-magnesium alloy?

What is aviation aluminum-magnesium alloy for sale? Airplanes are one of the mainstream means of transportation today, because of the attraction of the earth, the lighter the aircraft, the better. The lighter the aircraft, the higher, faster, farther it flies, and the greater the load. Therefore, the main material of the aircraft body is aluminum alloy, but it is not an ordinary aluminum alloy!

Compared with ordinary aluminum alloys, aluminum alloys for aircraft have higher requirements for strength, hardness, toughness, fatigue resistance and plasticity. Aviation aluminum is mainly used in fuselage trusses, wing skins, webs, seat slides, keel beams, wing trusses, side frames, fuselage skins, lower fuselage siding, main floor stringers, spar upper and lower edge strips and other parts. Today's aluminum alloys for aviation aircraft structures in all countries in the world are mainly high-strength 2 series (2024, 2017, 2A12, etc.) and ultra-high-strength 7 series (7075, 7475, 7050, 7A04, etc.), in addition to some 5 series (5A06, 5052, 5086, etc.) and 6 series (6061, 6082, etc.) and a small number of other series of aluminum.

Aluminum is lightweight, strong and corrosion-resistant, and although it loses some strength at high temperatures, its strength increases at sub-zero temperatures, which is very useful in aerospace because aircraft often fly in extremely low temperatures. During World War I, aluminum began to replace materials such as wood and canvas on aircraft as the main body of aircraft. The first all-metal aircraft, Junkers J 1, was designed by German aircraft designer Hugo Junkers in 1915 and had an aluminum alloy tube. Today, the use of aluminum in aviation has become increasingly complex, with parts such as fuselages, wings, doors, floors and seats almost entirely made of aluminum, with few parts that can be replaced by aluminum, and 80% of the Boeing 737's fuselage is made of aluminum.

The world's aviation manufacturing industry has entered a period of rapid development, the current private aircraft and civil aviation and large aircraft production is increasing year by year, aviation aluminum market scale in recent years will become larger and larger.
