Why should you use BS EN 3957 - Silver base alloy AG-B14001 for aerospace applications? 

Silver alloys are commonly used in the creation of jewellery. 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 3957 creates a standardized approach for manufacturers of silver-based alloy and filler metal and wire for brazing and to adhere to if they supply their metallic materials for use by the aerospace and defence industry.   

By adopting BS EN 3957, manufacturers can demonstrate the reliability of their metallic materials products and build trust for their use throughout the aerospace supply chain.
