Brazing Copper Sheet

Stay silv 5 silver brazing filler metal designed for copper to copper applications.

The equipment in this project can be bought for as little as 30 dollars. Cda copper tube handbook. Brazing is distinguished from welding because it uses an intermediary material usually a copper zinc alloy to join the two metal pieces rather than melting the pieces themselves. Four processes to consider when joining copper and copper alloys are mechanical couplings welding soldering and brazing.

Brazing is also much easier then welding it s a lot like using a glue gun. Bradford sheet metal joining copper sheet metal and soldering. Like many phosphorus copper brazing filler metals stay silv 5 will flow rapidly when heated quickly to its liquidus. It can also be used on copper to low zinc brass but this application requires use of stay silv white brazing flux.

Brazing is a quick and inexpensive alternative to welding. I use a paste flux which is self cleaning although you should still wipe it with some isopropyl alcohol afterwards. Brazed metal can also be stronger then welds. It takes skill to make the joint neatly.

Brazing takes place above 840 degrees f but below the melting point of the base metal source. Traditionally this was the filler used to finish cramped joints before hard solder became available. Brazing using a filler of high zinc brass it is easy to make brazed joints in copper items. Brazing is suitable for small parts and when high joint strength is required.

Make sure that you add some flux to the area to be soldered.
