Aluminum alloys are strong yet light metals that have found uses in almost every market. An alloy is a mixture of metals that, when together, are more useful than their constituents alone. A base metal (in this case aluminum), can be thought to be “improved” by small quantities of different metals, known as 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. 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. 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. 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). This article aims to show the properties and uses for 7075 aluminum, and highlight its strengths as an engineering material. 7075 aluminum is comp...
