Brazing sheet copper.
Copper phosphorous brazing welding rods.
The filler metal is a metal alloy that has a melting temperature below that of either the tube or fitting.
Use a torch that produces a high intensity flame.
Four processes to consider when joining copper and copper alloys are mechanical couplings welding soldering and brazing.
Steel stainless steel nickel alloys copper alloys cast iron tungsten carbide.
Brazed metal can also be stronger then w.
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.
The corresponding uns numbers are shown in table 5.
Brazing takes place above 840 degrees f but below the melting point of the base metal source.
The melting point of copper cu alloy uns c12200 is 1 981 f 1082 c.
Brazing is suitable for small parts and when high joint strength is required.
A brazed butt joint is not strong enough so an overlap must be used to give a bigger contact area for the join.
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.

Cu ni alloys are most often brazed with silver base brazing alloys.
The equipment in this project can be bought for as little as 30 dollars.
Recommended rods by metal type.
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.
Copper sheets plates are also noted for their high electrical and thermal conductivity and good corrosion resistance.
Quick and easy brazing aluminum copper and nonferrous metals.
Brazing is also much easier then welding it s a lot like using a glue gun.
Dovetailed castellated or cramped joints.
110 copper sheet plate is widely known for its architectural applications whereas the familiar green patina appearance is acheived when exposed to the elements copper sheets and plates have excellent hot or cold workability and is ductile when heated.
Alloys bcup 5 and bcup 3 are acceptable for use with cu nis of 10 or less nickel.
Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal.
