Aircraft aluminium 7075 materials CNC Machining Parts

7075 aluminum is a high-strength alloy widely used in aerospace and military applications due to its exceptional mechanical properties and resistance to stress corrosion. This alloy is primarily composed of zinc, with other elements like magnesium, copper, and chromium, which enhance its performance characteristics. When machined using CNC (Computer Numerical Control) technology, 7075 aluminum can be precisely shaped to meet the stringent specifications required for critical applications.
Material Properties:
Strength: 7075 aluminum exhibits remarkable tensile strength, comparable to many steels, making it ideal for applications that require high durability and load-bearing capacity.
Weight: Despite its strength, it remains lightweight, which is crucial in aerospace designs where minimizing weight is essential for fuel efficiency and performance.
Corrosion Resistance: While 7075 is less corrosion-resistant than other aluminum alloys, proper treatment and coatings can enhance its durability in harsh environments.
Machinability: CNC machining allows for complex geometries and tight tolerances, making 7075 a favored choice for custom components.
Thermal Conductivity: This alloy has good thermal conductivity, which can be beneficial in heat dissipation applications.
Applications:
Due to its high strength-to-weight ratio and machinability, 7075 aluminum is utilized in a variety of aerospace components, including:
Aircraft structures (fuselages, wings)
Military equipment (aircraft frames, missiles)
Automotive parts (chassis components, suspension)
Sports equipment (bicycle frames, high-performance sporting goods)
