A visitor at our booth during the 2013 SVC (Society of Vacuum Coaters) conference suggested this video. In the video, a piece of indium is rubbed against a piece of gallium. The result is the formation of a room temperature alloy (75.5%Ga/24.5%In, mp: 15.7°C).iframe class="youtube-player" frameborder="0" height="390"...

Growing Interest in Bi-Containing Solder Alloys: Bismuth Rocks!

0
0
If you haven’t heard about Bi-containing (bismuth) solder alloys recently, that may change in the near future. Low-melting Bi-containing solders are now in increasing use and gaining popularity due to their lower melting temperatures—58Bi/42Sn is eutectic at 138°C and 57Bi/42Sn/1Ag melts 137-139°C (both are Pb-free alternatives). A low-temperature solder is advantageous...
