Abstract
A brazed joint between a beryllium-base part and a copper-base part comprises a first layer of brazing material in contact with the beryllium-base part. This brazing material is an alloy that just prior to brazing consists essentially of silver and a minor constituent of either: (a) tin in a percentage of 4% to 15% by weight of the alloy, (b) silicon in a percentage of 1% to 5% by weight of the alloy, or (c) indium in a percentage of 6% to 25% by weight of the alloy. Contacting this first layer and brazed thereto is a second layer of a material that just prior to brazing consists essentially of silver. Between the second layer and the copper-base part, there is another brazed connection, which is formed at temperatures exceeding 600.degree. C.
