Aluminum has changed many different industries in the past 100 years. Due to the light weight and high strength of aluminum, many alloys such as 2024 alloy, 7075 T6 aluminum and 7150 aluminum are widely used on the aeroplane, making the aircraft a safe, economical and feasible mode of transportation.
Why is aluminum used in the aircraft industry
Two outstanding reasons why aluminum is so indispensable to the aerospace industry have been mentioned: high strength and weight ratio, which is of great value to the aerospace industry. The aircraft fuselage must be strong and durable enough to withstand the stress of take-off and landing over time.
At the same time, if the metal is too heavy, it will require more fuel consumption during the flight. This means that aluminum is generally a more cost-effective choice for aircraft. Strength and weight are not the only advantages of aluminum. Another major benefit of aluminum alloy is its superior corrosion resistance.
This is a major factor in aircraft durability. Aircraft are constantly affected by various factors and often experience extreme weather like freezing temperatures and various precipitations in high altitude areas.
In addition, aircraft aluminum is easy to shape. The aeroplane requires high precision to ensure aerodynamics, not to mention the small parts that can be found on the aircraft. The good formability makes it cost-saving.
What are the different uses of aluminum in airplanes
The skin of an airplane is usually made of aluminum. And most other metal parts on the plane are also made of aluminum. For example, the engine of a piston-driven airplane is made of aluminum. Most of the metal fixtures in the aircraft, such as seats, doors, cabinets, etc., are also made of aluminum.
What are the common aircraft aluminum
The alloy closely related to aircraft applications is 7075. 7075 is known for its excellent mechanical properties, ductility, high strength, toughness and fatigue resistance. Welcome to contact us for the 7075 aluminum cost.
In recent years, some higher performance alloys have been developed and replaced 7075 in for certain aerospace applications. One example is 2024, whose chemistry makes it ideal choice for the parts that require high cycle fatigue resistance.
Other popular alloys used in the aviation industry include 6061, 6063, 2014, 5052, 7050, 7085 and 7068.
