... a thin layer of the silver-copper eutectic composition alloy at the joint interface, which is molten at the process temperature. Aluminum alloy components can be joined similarly using this approach at temperatures close to 575 °C (1065 °F) [ Niemann and Wille 1978 ]. Such joints tend to be strong, being...
