Introduction

Aluminum alloys are known for their strong corrosion resistance characteristics and have high electrical conductivity. These alloys lose some of their strength when exposed to high temperatures and experience an increase in strength at subzero temperatures, and thus are good low-temperature alloys.

The following datasheet provides an overview of Aluminium/Aluminum 1188 alloy.
