How Does 2219-T851 Help the Aerospace Industry?

Aluminum is a well-suited metal for many different industries. It is one of the most used metals in the world known for its lightweight and corrosion resistance. Its excellent strength-to-weight ratio makes it suitable for use in manufacturing aircraft. In fact, it is the most used metal in the aerospace industry. It is used extensively to manufacture safe and fuel-efficient aircraft. Here, we will answer the question “How Does Aluminum Help the Aerospace Industry?” by exploring the common benefits of using aluminum alloys like 2219-T851 and AMS QQ-A-250/30. Let’s get started.

 

Strength: Commercially pure aluminum has an ultimate tensile strength of 90MPa, making it suitable for structural applications. Working with processes like cold rolling increases its strength. Further increase in strength can be achieved by alloying it with some elements, including copper, manganese, and silicon. Alloys like 2219-T851 are much stronger than pure aluminum and can be even more strengthened via heat treatment.

 

High Strength-to-Weight Ratio: Aluminum’s strength-to-weight ratio is much higher than that of constructional steel. This property makes it well-suited for building and designing structures that need to be strong and lightweight like airframes. Airframes are needed to be strong to handle the stresses of takeoffs and landings over time. Plus, airframes are required to be lightweight so they will consume less fuel during flights. That’s why aluminum alloys like AMS QQ-A-250/30 are the best choice for manufacturing aircraft, especially airframes.

 

Corrosion resistance: Aluminum creates a protective thin oxide coating when exposed to air, preventing the metal from making further contact with the environment. It is particularly helpful for applications like aircraft that are exposed to various types of corrosion. Generally, aluminum alloys have less corrosion resistance than pure aluminum, except for marine magnesium-aluminum alloys. This property can be further improved with different types of surface treatments such as anodizing, painting, or lacquering.

 

Strength at Low Temperatures: Aluminum alloys like 2219-T851 are proven to be useful for use in cold temperatures. Unlike metals like steel, which becomes brittle when exposed to low temperatures, aluminum alloys become stronger. Not only does the aluminum strength increase at sub-zero temperatures but also its yield, tensile, and impact measurements. Moreover, the corrosion resistance also increases in such conditions, making it well-suited for use in cold and ice regions where corrosion resistance is essentially needed.

 

Conclusion: Undoubtedly, aluminum is one of the most used metals in the world as well as in the aerospace industry. Its properties and features make it versatile and suitable for various applications. Are you an aerospace manufacturer seeking a supplier to purchase aluminum alloys at competitive prices?
