Applications of 7075 Aluminum
Type 7075 aluminum is one the strongest aluminum alloys. Its high yield strength (>500 MPa) and its low density make the material a fit for applications such as aircraft parts or parts subject to heavy wear. While it is less corrosion resistant than other alloys (such as 5052 aluminum alloy, which is exceptionally resistant to corrosion), its strength more than justifies the downsides. Some major applications of 7075 aluminum alloy include:
7075 aluminum alloy can be further improved by how it is strengthened using a process known as heat-treatment, sometimes referred to as “tempering.” This method uses high heat (300-500 ºC) to reconfigure the metal’s crystal structure to strengthen its overall mechanical properties, and can literally make-or-break a material. There are many methods of tempering 7075 aluminum, but to simplify this article, we will highlight T6 tempered 7075 aluminum alloy (7075-T6). 7075-T6 is a common temper for aluminum plate and bar stock; however, it is important to know that each tempering process gives 7075 aluminum its own distinct values and characteristics.
