The main advantages of having an exceptional strength-to-weight ratio are increased performance, improved durability, and reduced weight: you get high performance, efficient, longer lasting, and lighter components.
This feature is crucial in the aviation industry, where increased strength allows components to withstand greater stresses and strains over time without compromising performance. Improving performance allows parts to work effectively, demonstrating better overall performance.
Thermal stability means greater reliability and better performance. An improved reliability means that components are not affected by temperature variations, making them ideal for use in extreme and complicated environments. Improved performance allows parts to operate more efficiently over a wide range of temperatures, leading to better overall performance.
Aluminium 7075 is an aluminium alloy with zinc as the primary alloying element. It is one of the most popular aluminium alloys in the aerospace and defence industries due to its strength and fatigue resistance.
The properties of Aluminium 7075 are impressive, particularly its strength-to-weight ratio. In terms of strength, it is much stronger than other common aluminium alloys such as 6061-T6 and 5083-H112.
It has a tensile strength of at least 572 MPa, a yield strength of at least 503 MPa, and an elongation of at least 9%. In terms of weight, it is around 30% lighter than steel, making it an ideal material for weight-sensitive applications.
The advantages of Aluminium 7075 are numerous. Its strength-to-weight ratio makes it suitable for components where weight savings are important.
It also has excellent fatigue resistance, meaning it can withstand repeated loading without failure. It is also resistant to corrosion and can be welded, machined, and formed easily.
Aluminium 7075 is used in a variety of industries. It is widely used in the aerospace and defence industries, where its strength and fatigue resistance make it an ideal material for components.
It is also used in the automotive industry, where its light weight and corrosion resistance make it an ideal material for components such as suspension arms and brake calipers. In the marine industry, it is used for components such as propeller shafts and hull plates, due to its excellent corrosion resistance. It is also used in the sporting goods industry, where its strength and light weight make it an ideal material for components such as bicycle frames, golf clubs, and skis.
