Aluminum A413 vs 413: What’s the difference?

Aluminum 413 alloy should not be confused with A413 alloy. While both A413 and 413 are alloys of aluminum, they have slightly different characteristics. 413 Alloy has a higher Magnesium content than A413 but has a lower Iron content. The Elongation at the break for 413 is 2.5% while A413 is 3.5%. Also, A413 has higher thermal conductivity and coefficient of thermal expansion. Other than these, most of the mechanical and physical properties are quite similar.

A413 alloy is great for parts that must have high-pressure tightness. 413 has more balanced properties and is suitable for common die-casting applications. But it’s easy to get confused with so many choices for aluminum alloys. You can contact us without any hesitation if you need help choosing the right alloy for your project.
