Introduction

Aluminium /aluminum alloys have strong corrosion resistance. These alloys 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 aluminium / aluminum alloys can be enhanced at subzero temperatures, making them ideal low-temperature alloys.

The aluminium / aluminum 5154 alloy is a wrought alloy. The following datasheet will provide more details about the aluminium / aluminum 5154 alloy.
