You plan to join two copper plates by soldering or brazing B

You plan to join two copper plates by soldering or brazing. Both processes involve heating the metal to a high enough temperature that the filler material melts and is drawn into the joint. The difference is that soldering has an operating temperature below 450C, while brazing is above it. Question: If they are age-hardened Cu-2% Be alloy, could you use a stronger filler material with brazing? If so, what is a proper temperature range? Explain.

Solution

Yes, stronger filler material can be used by using Brazing, as the filler material (alloy) used for brazing is generally stronger than the materials being joined. The temperature range should be above 450 C but below the melting poing point of the two materials being joined.
