Introduction

Aluminum alloys are good low-temperature alloys as they gain strength when exposed to subzero temperatures. They have high electrical conductivity and strong corrosion resistance characteristics. These alloys lose their strength when exposed to high temperatures. Aluminum alloys are sensitive to high temperatures ranging between 200 and 250°C (392 and 482°F).
