Introduction

Aluminum alloys have strong corrosion resistance. They are sensitive to high temperatures ranging between 200 and 250°C (392 and 482°F), and tend to lose some of their strength. However, the strength of the aluminum alloys can be enhanced at subzero temperatures, thus making them good low-temperature alloys.

The aluminum 5457 alloy is a wrought alloy type. The following datasheet will provide more detail on this aluminum 5457 alloy.
