What Type Of Solder Do You Use For Copper?

Do you need flux to solder copper pipe?

Flux is a chemical which helps you solder.

Flux prevents the copper from oxidizing as you heat the copper with the torch.

In addition, it prevents the pipe from oxidizing as you heat it.

You can solder without flux, but it is really difficult!.

Can I use electrical solder for copper pipe?

Electrical solder is generally hollow, with a core made of a flux intended to solder copper wires. This flux is not made for copper water pipes. You will want to use a separate paste flux especially made for sweating copper water pipe (and a small brush to apply it). Some electrical solders contain an amount of lead.

Can I solder without flux?

It’s ok, if you can do it, but it’s very difficult to solder without flux. The flux breaks down the oxide layers on the metal surfaces and allows the solder to “wet” them. If it doesn’t wet, it doesn’t make a connection. … It’s normally always necessary to use flux when you solder.

Does solder stick to copper?

The surface of the copper is very smooth so thag when you apply the solder to it , it will not stick to it. To apply solder, the surface need to be rough or it should be tinned so when you apply solder it will melt and stick.

Can you melt copper wire with a soldering iron?

Because the soldering iron is extremely hot, don’t lay it down while you are looking for the next part to solder. You can buy a soldering kit, which includes a soldering gun and base, sponge and solder, which will generally be tin or silver and work fine with copper.

What do you need to solder copper?

How to Solder Copper Pipe JointsBuy a self-lighting torch. Good torches work faster. … Use a good-quality tubing cutter. Make clean, burr-free cuts. … Use a steel brush for complete cleaning of pipes and fittings. … Apply tinning flux rather than regular flux. … Assemble the pipes, then solder the joints all at once. … Heat the joint just enough to melt the solder.

Can you use a paperclip as solder?

This common mesh is galvanised steel i.e. steel which has been coated with zinc. Apparently paperclips are also made of galvanised steel as a rule, so there may be a connection here. … Other metals such as aluminium or regular steel can be soldered, but require special solder and flux and may need stronger equipment.

What are the three different types of solder?

In summary, there are three main types of solder: lead-based, lead-free, and flux. Lead-based solders are the best understood, are reliable, and preferred in mission critical applications such as aerospace or medical electronics.

What is the difference between plumbing solder and electrical solder?

Perhaps the key difference between electrical and plumbing solder is the type of flux used in each application. … The flux also aids wetting, helping the solder to flow and bond with the metals more readily. Typically, electrical solder contains rosin core flux; plumbing solder uses an acid-based flux.

What solder do plumbers use?

Acid core solders are most often used in plumbing applications to join metal pipes or sheet metal. Rosin core solder is also fabricated with a hollow core inside the solder wire, but the flux used is a milder variety made of rosin, which is a solid form of resin derived from conifers such as pine.

Can you overheat copper pipe when soldering?

Overheating is a major problem when brazing or soldering copper pipe because the flux will burn (become oxidized), stop working, and become a barrier to tinning. In addition, a heavy oxide can be formed on the pipe itself, preventing a bond from forming between the filler metal and the pipe surface.

What type of solder should I use?

For electronics soldering, the most commonly used type is lead-free rosin core solder. … You can also use leaded 60/40 (60% tin, 40% lead) rosin core solder but it’s becoming less popular due to health concerns. If you do use lead solder, make sure you have proper ventilation and that you wash your hands after use.

Can you use Vaseline as flux?

Vaseline is an “oil” based grease, it has no flux properties. (It WILL do the opposite job of contaminating your joint.) … The trick with flux is not the “feel”, > smell, or taste, but the ability to carry heat.

Why does my solder not stick to copper pipe?

The solder will “stick” to (wet) the pipe when the pipe is clean and hot enough to melt the solder. The copper joint areas must be bright clean on both inside and outside mating surfaces. … Use a propane torch to heat ONLY the outside PIPE fitting evenly.
