3 Main Properties of Aluminium 7075

Aluminium 7075 is a lightweight, high-strength aluminium alloy that has been used in many industries for decades. It is popular due to its strength-to-weight ratio, corrosion resistance, and durability. In this blog post, we will discuss the various uses of aluminium 7075 and why it is such an essential material for industrial applications.



Strength and Durability

Aluminium 7075 is an alloy with the highest strength of any other aluminium alloy available on the market. It offers an impressive yield strength of at least 574 MPa (83 ksi) and ultimate tensile strength of at least 828 MPa (120 ksi). This makes it suitable for use in structural components that must withstand significant stress levels or load. The durability of aluminium 7075 also means that it can be used in applications where longevity is key – from automotive parts to aerospace components.

Corrosion Resistance

Aluminium 7075 offers excellent corrosion resistance due to its chemical composition. It contains chromium, copper, magnesium, manganese, silicon and zinc, which all help to protect against corrosion in various environments. This makes it ideal for use in outdoor applications or those that may require exposure to saltwater or other corrosive substances. This also helps increase the component’s lifespan as it won’t degrade over time as some other materials would.


Aluminium 7075 can be easily welded with conventional welding techniques such as TIG or MIG welding. Depending on the application, a filler material may be necessary, but most welds can be completed without one if the correct procedures are followed. This makes aluminium 7075 an ideal option for those who need to combine two pieces quickly and efficiently without sacrificing strength or performance.




Aluminium 7075 is a versatile material with many uses across various industries, such as aerospace engineering, automotive manufacturing and marine applications. Its high strength-to-weight ratio makes it suitable for structural components, while its corrosion resistance ensures long-lasting performance even when exposed to harsh environments. Additionally, its weldability allows for quick assembly without compromising the component’s overall integrity, making it an excellent choice for anyone looking for a reliable material with superior performance characteristics. Whether you’re looking for something to use in aerospace engineering or automotive manufacturing, aluminium 7075 should definitely be considered!
