Brazing Copper Sheet

Brazing is a quick and inexpensive alternative to welding.

Brazing copper sheet.

In brazing the filler metal has a lower melting point than the adjoining metal. The equipment in this project can be bought for as little as 30 dollars. The phosphorus in these alloys acts as a fluxing agent on copper. Fluxing is an essential step in the brazing operation aside from a few exceptions.

The filler metal can be aluminum silicon brass bronze copper copper silver gold silver nickel alloy or silver. Brazed metal can also be stronger then welds. Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal. In actual practice for copper systems most soldering is done at temperatures from about 350 f to 600 f while most brazing is done at temperatures ranging from 1100 f to 1500 f.

The brazing rod should be melted by the heat of the metal pieces being joined not by direct contact with the flame of the torch. Brazing is similar to soldering but at higher temperatures.

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. The choice between soldering or brazing generally depends on the operating conditions of the system and the requirements of the governing construction codes. Brazing differs from welding in that it does not involve melting the work pieces and from soldering in using higher temperatures for a similar process while also requiring much. Use a torch that produces a high intensity flame.

In brazing and welding fabricators add a filler metal into the joint. You can join copper to copper without flux by using a brazing filler metal specially formulated for the job such as handy harman s sil fos or fos flo 7. However the major differences are the following.
