Comments  

General

Gold Tin (Au/Sn, or 80% gold, 20% tin by weight ) is a unique material. It is used in a variety of applications requiring a high reliability, high melting solder joint.  This particular alloy of gold tin (Au/Sn) has a melting temperature of 280ºC, which is lower than the 350ºC transition temperature into braze materials.  Still, there are some similarities between this solder alloy and braze alloys. The most obvious is the hardness of the gold tin (AuSn) alloy. With a tensile strength of 40,000PSI, this solder is much more rigid than the tin solders most are familiar with. The strength is more closely compared to the silver brazes which melt above 500ºC.
