Introduction

Aluminum alloys contain have strong corrosion resistance characteristics and high electrical conductivity. These alloys obtain high strength when exposed to subzero temperatures and experience a decrease in strength when exposed toat high temperatures ranging between 200 and 250°C (392 and 482°F). Hence, Aaluminum alloys are known as good low-temperature alloys and are sensitive to high temperatures ranging between 200 and 250°C (392 and 482°F).
