Products made from aluminum and its alloys are mostly popular for their strength-to-weight ratio, corrosion resistance, and strength. The majority of the alloys are easy to weld, CNC machine, and take through different forms of fabrication. Their recyclability is also resonating well with the present mantra of environmental sustainability.<\/p>\n

While these are desirable attributes for anyone looking for metal to use, they are general. When it comes down to a specific material, the qualities of an aluminum alloy can differ, even if slightly. That\u2019s the case for aluminum 7005 and aluminum 7075. If you are torn between these two alloys or just want to learn about them, this post is for you.<\/p>\n

We will look at the main properties of the 7075 and 7005 aluminum alloys, including chemical composition, physical properties, mechanical properties, applications, and the comparison of all these.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

What is 7075 aluminum?<\/strong><\/h2>\n<\/div>

7075 aluminum<\/a><\/strong> is a popular aluminum alloy from the 7000 series that we produce at the Fonnov Aluminum facility. It is extremely strong and relatively easy to machine, especially when you compare it with high-strength steel. Considering its superior strength, it is understandable why most of its applications are where strength is paramount. You will therefore find it in the aerospace and defense industries, as well as in other high-strength structures. Its rich concentration of zinc element is a key contributor to the characteristics we witness. Note that this alloy has a high strength-to-weight ratio, so it is perfect for areas where this combination of properties is needed.<\/p>\n<\/div><\/div><\/div>

Chemical Composition of 7075 Aluminum<\/em><\/strong><\/h3>\n<\/div>

For aluminum 7075, the components are magnesium 2.1-2.9 %, zinc 5.1-6.1%, Copper 1.2-2.0%, and Iron 0.50. The silicon and manganese contents are 0.40% and 0.30% respectively. Aluminum 7075 also contains smaller components of Titanium and Chromium among others. Similar to aluminum 7005, the rest of the composition is aluminum.<\/p>\n<\/div>\n
