Description

Aluminium is one of the most ubiquitous metals in the modern world, thanks to properties like high strength-to-weight ratio, high thermal and electrical conductivity, atmospheric corrosion resistance, workability and formability. These properties make it an ideal choice in applications as varied as the aerospace and construction industries, high-tech electronics, high voltage power lines, and more. These characteristics, along with its high recyclability, help improve life-cycle management, and reduce the overall economic and environmental impact of its application.
