SILVER ALLOYS

SILVER ALLOYS

small fot 50 1 - Silver alloys

Silver alloys are characterized by good brazing properties, exhibiting good shearing, fatigue and impact stress strength. They are resistant to acids and alkalis. Due to good wettability, they may be used for joining most metals and alloys, including: carbon, alloy and stainless steels as well as copper and its alloys.

REPLACEMETS FOR CADMIUM ALLOYS

The EU Commission Regulation No. 494/2011 came into force on 10 December 2011 prohibiting the use of cadmium alloys. As a result, LUT-SPAW has introduced cadmium alloys equivalents. As an alternative to this type of alloy we will suggest alloys containing tin. This element is added in order to lower the melting point and improve the wettability of solder on the silver base.
