   Nickel silver Beryllium copper: High thermal conductivity of these metals requires high heat input during soldering. Oxidizes quickly so proper flux must be used. Fair: Carbon steel Low alloy steel Zinc Nickel: Solder joints become brittle in sulfur-rich environments. Avoid higher temperatures in the presence of lubricants (which contain sulfur ...

4. Soldering - Wikipedia

   en.wikipedia.org/wiki/Soldering

   "Hard soldering" or "silver soldering" is used to join precious and semi-precious metals such as gold, silver, brass, and copper. The solder is usually described as easy, medium, or hard in reference to its melting temperature, not the strength of the joint. Extra-easy solder contains 56% silver and has a melting point of 618 °C (1,145 °F).

5. Solder - Wikipedia

   en.wikipedia.org/wiki/Solder

   Soldering performed using alloys with a melting point above 450 °C (840 °F; 720 K) is called "hard soldering", "silver soldering", or brazing. In specific proportions, some alloys are eutectic — that is, the alloy's melting point is the lowest possible for a mixture of those components, and coincides with the freezing point.
