Is brass the same thing as copper?
Copper is a pure metal while brass is an alloy of copper. As a result, the color copper is usually distinct enough to differentiate copper from brass. Copper is usually reddish-brown while brass may exist in a different color depending on its elemental components including golden yellow, reddish-gold, or silver.
Can You braze brass using copper?
Use high quality braze welding filler if color matching is not an issue. Because of copper's high melting point, low zinc brass can be braze welded or fusion welded. Step 5 Use a welding tip one size larger than you would use to weld steel of the same thickness, due to the higher heat conductivity of brass.
Can brass and or bronze be soldered to copper?

What is the best way to clean tubing?
Wire brush, scrubbing pad or steel wool – Cleans the tubing, removes any coating, and helps with adhesion. Soldering pad – Lies on a flat surface to support your soldering project and protect the surface beneath.
How to heat brass fittings?
Uncoil 8 inches of solder from its spool and bend 2 inches of the end at 90 degrees. Turn on the propane torch and heat the brass fitting evenly by moving the flame side to side. When you hear the flux sizzling, touch the end of the solder to the join between the brass and the copper. If it melts, the brass is hot enough.
How to make a copper pipe?
Step 1. Sand the end of the copper pipe with an emery cloth, as well as the inside of the brass fitting. Apply lead-free soldering paste, or flux, to the pipe end, as well as the inside of the brass fitting. Push the brass fitting onto the end of the copper pipe.
Why do brass fittings need to be removed?
Brass simply needs more heat than copper for the solder to melt into the joint between the two metals. Brass fittings, such as shutoff valves, have valve stems on the side of the fitting, which have rubber or plastic parts that you need to remove to protect them from the heat of soldering.
What metal is the hardest to solder?
About the only common metal that is very difficult to solder is aluminum. Stainless steel can be very difficult to solder if not prepared (freshly abraded to remove chromium oxide at the surface, which is what makes it stainless. I use 300 series welding filler wire for assorted things.
What is brass and bronze used for?
Various brass and bronze alloys are extremely common in electromechanical devices such as relays. For example, the moving contacts in relays may be mounted on bronze alloy spring "fingers" which have wires soldered between them and the brass pins that get soldered to a PCB or plugged into a socket.
What bronze bushing would give trouble?
The only bronze that I know of that would give trouble would be like an Oilite bushing, because of the oil in it.
Is lead free solder good for plumbing?
Lead-free solder is now the standard for plumbing, and produces stronger joints. Though no longer true in plumbing, many brass alloys contain some lead, which acts as a sort of built-in machining lubricant. Various brass and bronze alloys are extremely common in electromechanical devices such as relays. For example, the moving contacts in relays ...
Can you solder copper and tin?
Actually both tin and copper are solderable, so I don't see any problems with soldering bronze (provided the alloy is just those two elements).
Can you use copper to brass?
Copper to brass is a definite yes. I have done it many times, also brass to steel. All with leaded, rosin core solder. I have not tried bronze. Success with that might depend on the alloy.
Does zinc chloride cause corrosion?
Zinc chlor ide leads to a perpetual corrosion cycle - chlorine is a powerful oxidant and will react readily with the metal. Click to expand... Thanks for the warning, somewhere in the back of my head that's information that I had already learned, many years ago. Thanks for bringing it back to the surface.
What is the most important part of soldering brass?
The next most important part of soldering brass is to make sure it is clean. Brass will often have a protective covering to prevent it from tarnishing. This must be removed thoroughly before you begin to solder.
How to solder brass with flux?
Apply Flux to Your Brass Pieces. Flux cleans the metal and acts like a glue to hold the pieces together for soldering. You need a tin based flux, also known as a brass soldering flux. Using the paintbrush, spread the flux over the cleaned areas you will be soldering. Place the pieces together and heat with the torch.
How to remove flux from brass?
Cleaning with the water and baking soda will help remove any leftover flux. Flux can be corrosive to metals if not cleaned off. Now that you know how to solder brass effectively, you will be able to solder other metals, including silver and gold, more easily.
