Brazing Copper To Stainless

Apply flux to both surfaces to be brazed make sure you have a flux that is capable of etching stainless steel.

Brazing copper to stainless.

1400ºf to 1600ºf 760ºc to 871ºc time. Brazing stainless steels requires adequate planning as the alloys used to form joints must have properties compatible with the base metal. The copper pipes will pass steam raising from a container of boiling water. These alloys contain phosphorus and are self fluxing on copper.

This week i want to thank you for helping me out and share what you taught me about. 45 silver solder or better with white or brown flux to start but always point your flame at the copper allowing the ss to only get near the flame. Heating treating stainless steel requires a pure furnace atmosphere. Induction brazing test with ubraze was able to braze the parts in 9 to 11 seconds for the full braze cycle.

Ssf 6 silver solder and a propane torch are used to demonstrate how to join a piece of copper tubing to a piece of stainless steel tubing. The brazing process can yield strong joints that are ductile clean and smooth. 9 to 11 seconds. Slip parts together and start heating the copper in a circular motion making sure to heat.

Not using a pure atmosphere. When brazing brass or bronze fittings stay silv white flux is required with these alloys. Copper to stainless steel. When brazing iron steel or other ferrous metals select one of the stay silv brazing alloys such as safety silv 45 or safety silv 56 with safety silv white brazing flux.

However a key advantage is that many dissimilar metals can be joined to stainless steels by brazing. Once the solder melts onto the copper move some heat onto the ss. Clean the surface with steel wool or an emory cloth. The copper pipe where it penetrates each side of the stainless box must be water tight as the box will be filled with water.

These oxides inhibit the flow of brazing alloy and must be physically removed after the heat treating process. You guys helped me out with a bunch of kick ass brazing tips and tricks. The steam will not have any pressure as the opposite end will be open to the air. Do not use phosphorus bearing alloys as the joint may be brittle.

Once you do you will need to wash off your joint with cold water and do it again. Here are basic tips for silver brazing copper to steel or stainless steel. Clean and flux the area to be silver brazed use a tip that produces a flame that is hot enough to heat the area without taking all day but not so hot that it is hard to control. And don t burn the stainless.
