Alloys made of aluminium and manganese (AlMn alloys) have manganese (Mn) as their primary alloying component. They are primarily made of aluminium (Al); they may also contain iron (Fe), silicon (Si), magnesium (Mg), or copper (Cu), with manganese making up the majority of the alloying elements (around 1%).
AlMn is a wrought alloy that is nearly exclusively formed into sheets or profiles using rolling or extrusion presses. The alloys have low strengths for aluminium alloys, are resistant to corrosion, and cannot be made harder through heat treatment. The 3000 series includes these as standard.
The Global Aluminum Manganese Alloy Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
China’s aerospace aluminium alloy:7055,7085 aluminium alloy producer helped the country progress to the position of aerospace powerhouse Hay with the development of the 2219 aluminium alloy: aluminium-copper-manganese-titanium-vanadium-zirconium series alloy.
It’s important to note that, regardless of the type of spacecraft, the structural materials and launch rocket structural materials used are primarily aluminium, titanium, high-temperature steel, composite materials, etc., but aluminium is used the most, accounting for more than 80% of the total material consumption.
The mechanical qualities of aluminium alloy are great at low temperatures, and as the temperature drops, so do their strength and fluidity. Accordingly, the majority of structural steels have low-temperature brittleness while aluminium alloy does not.
Aluminium, copper, manganese, titanium, vanadium, and zirconium are the elements that make up the alloy 2219. The alloy is American. The manufacturing procedure has developed and is reliable. It is currently being mass-produced in China.
For the structure of the carrier rocket compartment, China currently uses the fourth-generation 7055 and 7085 alloy and the third-generation 2195 and 2197 aluminium alloys (all of which contain lithium).
For instance, ZGLV Aluminium Technology Group’s 5A06 and 2A14 aluminium alloys are used to weld the normal temperature propellant storage tank and the liquid hydrogen and liquid oxygen storage tanks of Beidou-3’s final networked satellite, respectively.
Both of these materials are used in the production of ZGLV Aluminium Technology Group. The manufacturer guarantees that the liquid oxygen kerosene fuel tank for rockets will likewise be welded using 2219 aluminium alloy plates.
