Brazing Sheet Copper

Dovetailed castellated or cramped joints.

Brazing sheet copper.

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. Recommended rods by metal type. The melting point of copper cu alloy uns c12200 is 1 981 f 1082 c. Copper phosphorous brazing welding rods.

Cu ni alloys are most often brazed with silver base brazing alloys. Fillers of aws a5 8 classifications bag 1a bag 2 bag 18 and bag 5 are ordinarily used. A brazed butt joint is not strong enough so an overlap must be used to give a bigger contact area for the join. The corresponding uns numbers are shown in table 5.

Copper sheets plates are also noted for their high electrical and thermal conductivity and good corrosion resistance. Traditional techniques involve cutting out copper sheet to form the sidewall forming it to cylindrical shape and making a joint. Steel stainless steel nickel alloys copper alloys cast iron tungsten carbide. Use a torch that produces a high intensity flame.

Nickel silver brazing welding rods. Quick and easy brazing aluminum copper and nonferrous metals. For over 25 years lynch metals has been north america s largest stocking distributor of aluminum brazing sheet stainless steel other metal alloys. Brazing is suitable for small parts and when high joint strength is required.

Home contact blog 888 272 9464 908 686 8401. Brazing is a quick and inexpensive alternative to welding. 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. Four processes to consider when joining copper and copper alloys are mechanical couplings welding soldering and brazing.

Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal. Brazing is also much easier then welding it s a lot like using a glue gun. Alloys bcup 5 and bcup 3 are acceptable for use with cu nis of 10 or less nickel. 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.

The equipment in this project can be bought for as little as 30 dollars. Brazed metal can also be stronger then w. Brazing takes place above 840 degrees f but below the melting point of the base metal source.
