Capalex Aluminium Extrusions

 

Introduction

Aluminium alloy 2024, is a high copper alloy and has a very high strength, slightly higher than 2014. With a high fatigue strength, this is used to an advantage on structures and parts where good strength to weight ratio are required.

 

Applications

Alloy 2024 commonly used for aerospace components – machined or fabricated items. Also used for engineering.

Aerospace materials are covered by the ‘L’ series of British standards.
