AMS 4006 Aluminum Alloy – Composition, Properties and Uses

AMS 4006

AMS4006 is a popular material used in the aerospace industry for its high strength and corrosion resistance. With such properties, it’s no wonder it’s in high demand. This blog post will comprehensively explain AMS 4006’s composition, physical and mechanical properties, uses, and heat treatment.

What is AMS 4006?

AMS 4006 (also known as 3003 Aluminum Alloy) is a specification that is used in the aerospace industry when it comes to aluminium alloy 3003. This specification outlines the requirements that must be met for aluminium alloy products to be considered safe and reliable for use in aircraft. Everything must be carefully checked, from the chemical composition to the mechanical properties, before the product can be considered usable. With the aerospace industry being one of the most highly regulated industries worldwide, it is probably no surprise that a highly specific and detailed specification such as the AMS4006 is necessary for keeping everyone safe in the air.
