The modulus of elasticity for 7075 aluminum is 71.7 GPa (10,400 ksi), and it's shear modulus is 26.9 GPa (3900 ksi) (see Table 1 for a summary).
The measure of a material’s resistance to deformation is given by its modulus of elasticity and shear modulus. 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. There are many methods of tempering 7075 aluminum, but to simplify this article, we will highlight T6 tempered 7075 aluminum alloy (7075-T6). The copper content of 7075 aluminum increases its susceptibility to corrosion, but this sacrifice is necessary to make such a strong-yet-workable material.ħ075 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 ✬) to reconfigure the metal’s crystal structure to strengthen its overall mechanical properties, and can literally make-or-break a material. 7075 aluminum alloy is one of the strongest aluminum alloys available, making it valuable in high-stress situations. Its density is 2.81 g/cm3 (0.102 lb/in³), which is relatively light for a metal. Physical Properties of 7075 Aluminumħ075 aluminum is composed of 90.0% Al, 5.6% Zn, 2.5%Mg, 0.23%Cr, and 1.6% Cu, though these numbers nominally fluctuate depending upon manufacturing factors. This article aims to show the properties and uses for 7075 aluminum, and highlight its strengths as an engineering material. The other three digits in its name specify individual alloys from each other within its series (for a more in-depth explanation of this naming convention, see our article on 6061 aluminum alloy). The topic of this article is from the 7xxx series, or alloys which use zinc as their main alloying element, and its name is type 7075 aluminum alloy. Aluminum is a very common metal that has many useful alloys so many in fact that the Aluminum Association has defined classes of these alloys using a numbered-naming scheme based on alloying elements. Alloys have been invented to provide stronger, more conductive, and/or more resilient materials for designing new ideas, and have revolutionized our engineering capabilities.
A base metal (in this case aluminum), can be thought to be “improved” by small quantities of different metals, known as alloying elements. An alloy is a mixture of metals that, when together, are more useful than their constituents alone. Aluminum alloys are strong yet light metals that have found uses in almost every market.
