Raw material properties of aluminum alloy 7075-T651

Aluminum alloy 7075-T651 is an excellent choice for making precise CNC machined parts including CNC machining prototype parts to be used in vehicle or aircraft applications. This alloy is renowned for its superior mechanical properties and is widely used in the aerospace and automotive industries for aluminum CNC rapid prototype machined parts or production parts.

The 7075-T651 alloy is known for its exceptionally high strength-to-weight ratio, which is crucial for components used in vehicles and aircraft, where weight savings can significantly improve performance and efficiency. With a tensile strength of up to 572 MPa (83 ksi) and a yield strength of up to 503 MPa (73 ksi), this alloy is significantly stronger than the more commonly used 6061-T6 alloy, making it an ideal choice for high-stress applications.

In addition to its impressive strength, the 7075-T651 alloy also exhibits excellent machinability, allowing for the production of precise, complex CNC machined parts. The alloy's relatively low hardness (Brinell hardness of around 150) and fine grain structure enable CNC machines to hold tight tolerances, typically within ±0.025 mm (±0.001 inches) or even tighter, depending on the specific application. This level of precision is essential for ensuring the proper fit and function of critical components in vehicle and aircraft systems.

Furthermore, the 7075-T651 alloy offers good corrosion resistance, which is crucial for parts exposed to harsh environments, such as those found in automotive and aerospace applications. This resistance to corrosion helps to extend the service life of the components and ensures their long-term reliability.

By leveraging the exceptional mechanical properties, machinability, and corrosion resistance of the 7075-T651 aluminum alloy, manufacturers can produce high-performance, precision-engineered parts that meet the stringent requirements of the vehicle and aircraft industries. This makes the 7075-T651 alloy an ideal choice for a wide range of critical components, from engine and suspension parts to airframe structures and aerospace mechanisms.
