Brazing Sheet Copper

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.

Brazing sheet copper.

Brazing is also much easier then welding it s a lot like using a glue gun. Copper sheets plates are also noted for their high electrical and thermal conductivity and good corrosion resistance. The corresponding uns numbers are shown in table 5. As such the filler metals for soldering and brazing copper and copper alloy tube and fittings must have melting temperatures below this temperature.

Nickel silver brazing welding rods. Steel stainless steel nickel alloys copper alloys cast iron tungsten carbide. Fillers of aws a5 8 classifications bag 1a bag 2 bag 18 and bag 5 are ordinarily used. Brazing is a quick and inexpensive alternative to welding.

Home contact blog 888 272 9464 908 686 8401. Traditional techniques involve cutting out copper sheet to form the sidewall forming it to cylindrical shape and making a joint. Quick and easy brazing aluminum copper and nonferrous metals. Cu ni alloys are most often brazed with silver base brazing alloys.

Brazing takes place above 840 degrees f but below the melting point of the base metal source. 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. Alloys bcup 5 and bcup 3 are acceptable for use with cu nis of 10 or less nickel. Dovetailed castellated or cramped joints.

The melting point of copper cu alloy uns c12200 is 1 981 f 1082 c. The equipment in this project can be bought for as little as 30 dollars. Use a torch that produces a high intensity flame. Copper phosphorous brazing welding rods.

A brazed butt joint is not strong enough so an overlap must be used to give a bigger contact area for the join. Four processes to consider when joining copper and copper alloys are mechanical couplings welding soldering and brazing. Brazed metal can also be stronger then w. The filler metal is a metal alloy that has a melting temperature below that of either the tube or fitting.

Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal. Cda copper tube handbook. 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.
