Brazing Sheet Copper

Fillers of aws a5 8 classifications bag 1a bag 2 bag 18 and bag 5 are ordinarily used.

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. A brazed butt joint is not strong enough so an overlap must be used to give a bigger contact area for the join. Quick and easy brazing aluminum copper and nonferrous metals. Brazing is suitable for small parts and when high joint strength is required.

Recommended rods by metal type. Cda copper tube handbook. Brazing takes place above 840 degrees f but below the melting point of the base metal source. Traditional techniques involve cutting out copper sheet to form the sidewall forming it to cylindrical shape and making a joint.

Brazed metal can also be stronger then w. Copper phosphorous brazing welding rods. 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.

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. Home contact blog 888 272 9464 908 686 8401. Use a torch that produces a high intensity flame.

Copper sheets plates are also noted for their high electrical and thermal conductivity and good corrosion resistance. Cu ni alloys are most often brazed with silver base brazing alloys. Steel stainless steel nickel alloys copper alloys cast iron tungsten carbide. Dovetailed castellated or cramped joints.

The filler metal is a metal alloy that has a melting temperature below that of either the tube or fitting. For over 25 years lynch metals has been north america s largest stocking distributor of aluminum brazing sheet stainless steel other metal alloys. Alloys bcup 5 and bcup 3 are acceptable for use with cu nis of 10 or less nickel. Nickel silver brazing welding rods.

The melting point of copper cu alloy uns c12200 is 1 981 f 1082 c. As such the filler metals for soldering and brazing copper and copper alloy tube and fittings must have melting temperatures below this temperature. Brazing is a quick and inexpensive alternative to welding.
