Why is Aluminum Alloy A7075 Used in the Aviation Industry?

Aluminum alloy A7075 belongs to the group of high-grade aluminum alloys, outstanding with high mechanical strength, good load-bearing capacity, especially widely used in the aviation, military and precision machinery manufacturing industries. Thanks to the optimal alloy ratio, A7075 has strength almost like steel but is 30-40% lighter, helping to increase performance and reduce weight for high-tech products.

Chemical Composition Of Aluminum A7075

Element Content (%) Effect
Aluminum (Al) ~90% Main ingredients, help reduce weight
Zinc (Zn) 5.1 - 6.1% Increased tensile strength, good load bearing capacity
Magnesium (Mg) 2.1 - 2.9% Improved corrosion resistance
Copper (Cu) 1.2 - 2.0% Increased hardness and heat resistance
Chromium (Cr), Manganese (Mn) Small amount Increased flexibility and high strength

Comments: The combination of these alloying elements gives Aluminum A7075 the highest strength among aluminum alloys, ideal for applications requiring good strength and resistance to deformation.

Why Is Aluminum A7075 Preferred In The Aviation Industry?

Aluminum A7075 is considered the standard material in the aviation industry due to its ideal strength/weight ratio, heat resistance, corrosion resistance and ease of machining.

Outstanding Strength/Weight Ratio

  • Tensile strength up to 572 MPa, 2 times higher than 6061 aluminum, increasing load-bearing capacity.
  • 35% lighter than steel, helping to reduce aircraft weight, improve flight performance and save fuel.

Practical applications: Landing gear, airframe, propellers of UAVs, drones – parts that require high durability but must be lightweight.

Good Corrosion and Heat Resistance

  • Good anti-oxidation and anti-corrosion, stable operation in high humidity, sea salt and chemical environments.
  • High heat resistance, no deformation when the aircraft operates at high altitudes and extreme temperatures.

Practical applications: Engine frame parts, transmission systems, rocket casings – parts exposed to high temperatures and harsh environments.

Easy to Process, Suitable for Aircraft Parts Production

  • High precision CNC machining, creating complex details such as airframes, landing gear, and load-bearing plates.
  • Can be anodized or painted, which increases corrosion resistance and extends product life.

Practical applications: Propeller components, airframes, engine covers, flight control components – requiring precision machining and durable surfaces.
