Brazing Copper Sheet

Brazing is a metal joining process in which two or more metal items are joined together by melting and flowing a filler metal into the joint the filler metal having a lower melting point than the adjoining metal.

Brazing copper sheet.

Brazing is similar to soldering but at higher temperatures. 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. Bradford sheet metal joining copper sheet metal and soldering.

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. 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. The filler metal can be aluminum silicon brass bronze copper copper silver gold silver nickel alloy or silver.

Use the right brazing rod material for the metal used in your project. 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 also much easier then welding it s a lot like using a glue gun. Brazing is a quick and inexpensive alternative to welding.

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. In brazing and welding fabricators add a filler metal into the joint. Bradford sheet metal joining copper sheet metal and soldering. 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.

Use a torch that produces a high intensity flame. Fluxing is an essential step in the brazing operation aside from a few exceptions. However the major differences are the following.
