Industrial gold brazing alloys

Wettability of Brazing Filler Metals on Copper and Copper Alloys

The possibility of alloying can not be avoided at the interface between molten brazing filler metal and base metal in brazing, so the wettability of brazing filler metal can not be easily explained theoretically. We used the original apparatus for wettability test and investigated the relation between the wettability of brazing filler metals of Ag-P-Cu and Ag-Cu-Zn-Cd systems on copper and the ...

VACUUM BRAZING BETWEEN SiCp/6063 Al MMCs AND Fe-Ni ALLOYS

Article history: Received: 4.9.2015. Received in revised form: 1.12.2015. Accepted: 2.12.2015. This research paper deals with the joining of different materials such as SiCp/6063Al MMCs and Fe-Ni alloys by means of vacuum brazing with active filler metal Ag47-Cu18-In17-Sn17-Ti1. With the optimal process parameters, i.e., brazing temperature 580 °C, soaking time of 30 min and vacuum degree of 6....

Industrial Applications for Shape Memory Alloys

Although medical applications for shape memory alloys (SMA) now dominate in today’s market, there are many applications in the industrial sector which have reached large volume production that far surpass the material usage in the medical fields. In the early growth of shape memory alloy technology the most important applications were for fasteners and couplings, mainly in the military sector. ...

Characterization of 14 Karat Gold Alloys

This paper is a continuation of the project we presented at the 2010 Santa Fe Symposium® in which we defined a characterization system and analysis of data on 18K gold alloys. The research carried out since then has enabled us to connect the physical-mechanical characteristics of each alloy with its chemical composition, thereby identifying the best solution possible to produce a specific item....
