Why should you use BS EN 3956 - Silver base alloy for aerospace series?
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 3956 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 3956 has been prepared in accordance with EN 4500-6. It covers all the requirements for silver base alloy and filler metal and wire for brazing.
BS EN 3956 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 3956, manufacturers can demonstrate the reliability of their metallic materials products and build trust for their use throughout the aerospace supply chain.
