Brazing is a quick and inexpensive alternative to welding.
Brazing sheet copper.
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.
Quick and easy brazing aluminum copper and nonferrous metals.

Cu ni alloys are most often brazed with silver base brazing alloys.
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 filler metal is a metal alloy that has a melting temperature below that of either the tube or fitting.
The melting point of copper cu alloy uns c12200 is 1 981 f 1082 c.
Use a torch that produces a high intensity flame.
Traditional techniques involve cutting out copper sheet to form the sidewall forming it to cylindrical shape and making a joint.
The equipment in this project can be bought for as little as 30 dollars.
As such the filler metals for soldering and brazing copper and copper alloy tube and fittings must have melting temperatures below this temperature.
A brazed butt joint is not strong enough so an overlap must be used to give a bigger contact area for the join.
Fillers of aws a5 8 classifications bag 1a bag 2 bag 18 and bag 5 are ordinarily used.
For over 25 years lynch metals has been north america s largest stocking distributor of aluminum brazing sheet stainless steel other metal alloys.
Copper sheets plates are also noted for their high electrical and thermal conductivity and good corrosion resistance.
Four processes to consider when joining copper and copper alloys are mechanical couplings welding soldering and brazing.
Alloys bcup 5 and bcup 3 are acceptable for use with cu nis of 10 or less nickel.
Brazing is also much easier then welding it s a lot like using a glue gun.
Brazed metal can also be stronger then w.
Steel stainless steel nickel alloys copper alloys cast iron tungsten carbide.
Brazing takes place above 840 degrees f but below the melting point of the base metal source.
Nickel silver brazing welding rods.
The corresponding uns numbers are shown in table 5.
Copper phosphorous brazing welding rods.
Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal.
Dovetailed castellated or cramped joints.
Brazing is suitable for small parts and when high joint strength is required.
