Commonly used metal materials and their performance characteristics for aerospace components in aviation parts processing plants

Today, let's take a detailed look at the commonly used metal materials for aerospace components and their performance characteristics.

One: Aluminium alloy

​

Aluminum alloy, as a material, has many advantages, such as low density, corrosion resistance, high strength, high rigidity, and low difficulty in processing and forming. Therefore, as long as it is 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 instance, researchers have significantly enhanced the corrosion resistance of aluminum alloy by subjsting it to heat treatment, effectively improving the safety of aircraft.

With the progress of The Times, new types of aluminum alloy materials have also been developed, which enables each alloy to have different properties and characteristics. As a result, their load-bearing capacity and fatigue resistance life have been greatly enhanced in different application parts.

Two: Titanium Alloy

According to research findings, titanium and titanium alloy materials have relatively low density but high specific strength. They also possess characteristics such as corrosion resistance, high-temperature resistance, stable performance, and non-magnetism. This material can be directly connected to composite material structures. Due to the similar thermal expansion coefficients between titanium alloys and composite materials, electrochemical corrosion is less likely to occur between them, and their comprehensive performance is relatively excellent.

Therefore, titanium alloys are also widely used in the aerospace field. When an aircraft is flying at high speed, the surface temperature of the fuselage may exceed the limit of conventional aluminum alloys. However, if other materials, such as steel, are used as the fuselage material, it will lead to an increase in the weight of the fuselage, affecting the flight speed and ceiling.

If titanium alloy is used for the fuselage, not only can the problem of surface temperature of the fuselage during high-speed flight be solved, but also the total weight of the fuselage can be reduced. It can be said that the use of titanium alloy materials greatly improves the performance of the aircraft.

Titanium alloy is also a major material when manufacturing aero engines. Another important application of titanium alloy is that it can be used as a material for fasteners such as bolts and rivets. Although fasteners are small in size, they play an important role in the aerospace field. The use of titanium alloy fasteners can significantly reduce weight.

Three: Ultra-high strength steel

Ultra-high strength steel not only has advantages that other materials do not have in terms of strength, rigidity, toughness and price, but also has obvious advantages under extremely high load conditions. Under extremely high load conditions, it not only has good reliability but also a long service life. Therefore, this material is widely used in the aerospace field.

For instance, ultra-high strength steel is used in the manufacturing process of aircraft landing gears. Due to the fact that landing gears need to withstand complex loads such as impact, and the loads they need to bear are relatively large, while ensuring that the landing gear can bear the load, the volume of the landing compartment is relatively small. The advantages of high strength and stability of ultra-high strength steel make it the preferred material for landing gears.

Four: Magnesium Alloy

Magnesium alloys have a low density, light weight, strong shock resistance and the ability to withstand large impact loads, which makes them widely used in the field of spacecraft. They are mainly used as materials for aircraft components such as frames, seats, engine casings and gearboxes.

After reading the above introduction, it can be known that aluminum alloys, titanium alloys, ultra-high strength steels and magnesium alloys are commonly used metal materials in the manufacturing process of aerospace components.
