Which Type Of Solder Is Best For Copper Pipe?

Which Type Of Solder Is Best For Copper Pipe

A solder is an object used for joining two things together, especially pipes and wires. The basic usage of solder doesn’t need many tools and elements.

If you want to join your copper pipes together, then you may choose lead-free solder for your soldering.

There are two types of solder: lead-free and lead-based. Lead-based solder is for those who are well experienced in soldering and for tough and big projects.

It is because lead-based solder is way too tough to handle for beginners, while lead-free ones are really easy to use and to handle.

This is why lead-free solder is highly recommended for beginners. However, in some cases, the soldering needs to be done with a mixture of lead-free and lead-based solders.

If you use the mixture, you will get more tin and less lead in your solder. For some products, the mixture is just what you need to get the work done perfectly.

For copper, lead-free solder is what you call the perfect companion. You will get the lead-free solder in any store’s plumbing section.

You may wonder why isn’t lead-based solder capable of copper. It is because lead-based solder can damage your water pipe. This is why lead-free solder is perfect for copper pipes.

Things To Consider While Buying The Solder For Copper Pipe

Things To Consider While Buying The Solder For Copper Pipe

Here’s what you should know before buying the best solder for your copper pipe:

The Flux Core

There are two types of flux cores well known for soldering on a regular basis. For electronic works, the acid core is used in most cases. On the other hand, the Rosin core is used for plumbing cases.

Both are different in their characteristics. So, select which type of core you need before jumping into the soldering.

Choose Lead-Based Or Lead-Free Solder

Depending on your work, you have to select if you want to go with lead-based solder or with lead-free ones. Lead-free solder is highly recommended for beginners as they are easy to work with and to handle.

Lead-based solder tends to be a little bit tough for beginners to handle. However, you can also go for the mixture of lead-based and lead-free solder. In the mixture, you will get in more than the lead in your solder.


The diameter of your solder is very important for the joints. For example, if your diameter is large, then the join would be large too.

The diameters that are large in size are meant for big projects of tough work, where you need to join a lot of objects together or where the joint needs to be very large.

However, for basic soldering, it would be best for you to select 0.062 inches or 0.032 inches of diameter in your solder.

The Spool

You need to check the size of the spool, too, besides the diameter. The perfect size of the spool that you need depends on your usage. It is because every solder has its lifespan depending on the alloy and the flux.

So, selecting the perfect size is important to avoid loss as it is recommended to change the solder every six months, and for non-based ones, the solder needs to be changed within a year.

For basic and small projects, a spool of 5 ounces is supposed to be enough and perfect to go with.

Melting Point

The melting point is another issue to look into. If the solder melts at the least temperature, you cannot use it to fix your copper pipes. Always choose solder that can deal with high temperatures.

Frequently Asked Questions (FAQs)

What Kind Of Solder Do You Use For Copper Pipes?

For your copper pipes, in case if you are using them for your water supply, you will need 100% lead-free solder. Though in other cases, a combination of other materials won’t do much harm.

You will find this kind of solder in the plumbing section of any store. Otherwise, lead solder can leach into your water supply.

Can I Use An Electrical Solder On A Copper Pipe?

It’s better to use lead-free solder for your copper pipes. Otherwise, you will face water supply issues.

Although electrical solders provide heavy-duty performance, they include lead. That’s why it’s not appropriate to use electrical solder for copper pipes.

Can I Use Regular Solder In Extreme Heat Changes?

No, not at all. In extreme temperature changes and vibrations, you will need the wire solder, which is made with such kinds of materials that can tolerate heat changes and vibrations.

Other solders won’t be able to deal with the temperature changes and vibrations. Your copper pipes will be destroyed in that case.

Can You Overheat Copper Pipe When Soldering?

Never do so. If you overheat copper pipe while soldering, then the flux will burn out, and your copper pipe will be ruined.

The whole copper pipe system will stop working. There will be a huge mess in that case. So never overheat the copper pipe even when soldering.

What Is The Best Flux For Soldering Copper Pipes?

Tinning flux undoubtedly. They are made in a way that they are ideal for soldering copper pipes. They help with any kind of water leak.

If you want to use flux as a replacement for the solder, then you can do so. They work pretty well with copper pipes.
