Why should you use BS EN 4324- Aluminium alloy AL-W42201 aerospace series?
An aluminium alloy is an alloy in which aluminium is the predominant metal. The mechanical and other properties of the alloy, differ with the change in the composition of the elements used in it, and hence, their application changes accordingly.
BS EN 4324 is part of the series of EN metallic materials for aerospace applications. The general organization of this series is described in EN 4258.
BS EN 4324 has been prepared in accordance with EN 4500-2. It covers all the requirements for aluminium alloys, filler metal for welding and rod.
BS EN 4324 creates a standardized approach for manufacturers of aluminium alloys, filler metal for welding and rod and to adhere to if they supply their metallic materials for use by the aerospace and defence industry. 
By adopting BS EN 4324, manufacturers can demonstrate the reliability of their metallic materials products and build trust for their use throughout the aerospace supply chain.
