Metal materials commonly used in aerospace parts processing plants and their performance characteristics
Today we will discuss in detail the commonly used metal materials and their performance characteristics for aerospace components.
1： Aluminum alloy
Aluminum alloy has many advantages, such as low density, corrosion resistance, high strength, high stiffness, and low processing difficulty. Therefore, as long as used properly, it can become an ideal material in the aerospace field.
With the development of the aerospace industry, people's requirements for aluminum alloys are constantly changing, making their performance increasingly powerful. For example, researchers have significantly improved the corrosion resistance of aluminum alloy materials through heat treatment, effectively enhancing the safety of aircraft.
With the progress of the times, new aluminum alloy materials have also been developed, allowing each alloy to have different properties and characteristics, greatly improving its load-bearing capacity and fatigue life in different usage areas.
2： Titanium alloy
According to research, titanium and titanium alloy materials have a relatively low density but high specific strength, and possess characteristics such as corrosion resistance, high temperature resistance, stable performance, and no magnetism. This material can be directly connected to the structure of composite materials. Due to the similar thermal expansion coefficients between titanium alloys and composite materials, they are less prone to electrochemical corrosion, and their overall performance is excellent.
Therefore, titanium alloys are also widely used in the aerospace industry. When an aircraft is flying at high speeds, the surface temperature of the aircraft body may exceed the limit of conventional aluminum alloys. However, if other materials, such as steel, are used as the material for the aircraft body, it will increase the weight of the aircraft body, affecting flight speed and lift.
If titanium alloy is used for the fuselage, it can not only solve the problem of surface temperature during high-speed flight, but also reduce the total weight of the fuselage. It can be said that the use of titanium alloy materials greatly improves the performance of the aircraft.
When manufacturing aviation engines, titanium alloy is also the main material. Another important use of titanium alloy is that it can be used as a material for fasteners such as bolts and rivets. Although fasteners have a small volume, they play an important role in the aerospace industry, and the use of titanium alloy fasteners can greatly reduce weight.

3： Ultra high strength steel
Ultra high strength steel not only has advantages in strength, rigidity, toughness, and price that other materials do not have, but also has obvious advantages under extremely high load conditions. Under extremely high load conditions, it not only has good reliability, but also has a long service life. Therefore, this material is widely used in the aerospace field.
For example, in the manufacturing process of aircraft landing gear, ultra-high strength steel is used. Due to the complex loads that landing gear needs to withstand, such as impacts, and the large loads it needs to bear, while ensuring that the landing gear can bear the load, the landing gear compartment volume is relatively small. The high strength and stability advantages of ultra-high strength steel make it the preferred material for landing gear.
4： Magnesium alloy
Magnesium alloy has a low density, light weight, strong seismic resistance, and can withstand large impact loads, making it widely used in the field of spacecraft. It is mainly used as a material for aircraft frames, seats, engine casings, and gearboxes.
After reading the previous introduction, it can be known that aluminum alloy, titanium alloy, ultra-high strength steel, and magnesium alloy are commonly used metal materials in the manufacturing process of aerospace components.
