What flux do you use for copper?

Superior No. 135 is a rosin/petrolatum soldering flux paste ideal for use with copper. The petrolatum helps protect the solder joint against attack, and the rosin leaves a protective coating over the solder area after soldering.

What solder should you use for copper?

lead-free solder

Types of Solder

Buy lead-free solder that’s designed for copper water pipes; you’ll find it in the plumbing section of the store. Solder with lead is still available, but the lead can leach into your water supply, so don’t use it.

Can you use water soluble flux for copper?

Description: Canfield Water-Soluble Flux is formulated for use in plumbing applications where copper and copper alloy tubes are being soldered. It is also an excellent choice for copper pipes used in heating, air conditioning, mechanical and fire sprinkler systems.

Can you sweat copper pipe without flux?

If there really was no flux then you have a “cold” solder joint. The solder may stick in spots but it will not have “wicked” into the “sweat” joint properly and will not completely seal the joint.

Do you need flux for copper to copper?

Do you need flux to solder copper?

Quote from the video:
Quote from Youtube video: Number one is how much flux to use flux cleans the copper. And also for the solder to adhere to the surface.

Is brazing flux the same as soldering flux?

For instance, flux used in electrical soldering typically contains a rosin core while flux for brazing applications might use borax or other compounds. Soldering is typically used in electronic applications, primarily to make an electrical connection.

Are there different types of soldering flux?

There are three different categories of fluxes used for soldering electronics according to IPC J-STD-004B. These categories are; Rosin and Rosin Substitutes, Water Soluble, and No-Clean.

Can I use Vaseline instead of flux?

Yes, Vaseline works just as well as commercial flux, and you can even buy a generic brand. Petroleum jelly is primarily made from waxes and mineral oils so that it won’t corrode your components. Plus, it cleans away the gunk and eliminates metal oxides that could compromise your bond.

Does flux damage copper pipe?

When Flux goes wrong!

The flux will corrode the pipe at the joint and some will be pushed around the system to find other things to corrode, maybe inside your boiler. The bottom line is that misuse of flux is commonplace and causes problems large and small.

What can I use instead of flux?

Petroleum jelly is the best effective alternative to commercial flux. Its waxes and mineral water ingredients make it antioxidant thas why you can easily use it as a soldering flux.

Is Borax used for flux?

Flux. A mixture of borax and ammonium chloride is used as a flux when welding iron and steel. It lowers the melting point of the unwanted iron oxide (scale), allowing it to run off.

How do you make homemade flux?

Quote from the video:
Quote from Youtube video: It's cheap very cheap to make the flux i add some california chips to an empty pill bottle. And then fill the bottle. About three-quarter full of alcohol. The flux will immediately start to dissolve.

Can you use lemon juice as flux?

Lemon juice can also be used as a great cheap alternative to flux!

What is solder flux made of?

The most basic soldering flux, one that has been used for over a thousand years, is the natural rosin derived from pine tar resin. Pine tar resin is dissolved in solvent and then distilled to yield the clear, water-white rosin used in soldering flux.

What is brazing flux made of?

Fluxes for silver brazing are typically composed of potassium salts or fluorides and borates in a water base. Several flux types are available to cover all possible base metals and/or conditions during brazing.

Do you need flux when soldering?

Flux core solder has flux in the center of the solder wire. Additional flux is unnecessary for most applications, but using additional flux still may make the solder easier to work with for some tasks. When selecting flux core solder, it is important to use rosin core solder for electrical applications.

What is soldering flux paste used for?

Solder paste flux serves a threefold purpose: Removing any oxidized metal from the surfaces to be soldered. Sealing out air, preventing further oxidation. Improving wetting characteristics of liquid solder by facilitating amalgamation.
