Other than welding and brazing, soldering is applied to join metals. Moreover, welders prefer soldering when they have to make joints between two thin metals. It allows you to execute your project without tearing the base metals like welding. The reason is you can join two base metals by melting a filler metal known as solder. In this article, we are going to know acid core vs. rosin core solder.

A general overview:
- Exceptional for plumbing works
- You can use this solder to join metal pipes and sheets
- It left behind a debris
- Best for use in electronic devices soldering
- It is non-corrosive
- Trash will not reserve over the joint
It is important to understand which type of solder you need for your project because both acid core and rosin core solders have their advantages and drawbacks over each other. So, after reading the article throughput, you will be in the position to choose the appropriate solder for your project.
Acid core solder
This is a type of solder that comes in the form of a wire with a hollow core. In the hollow body, acid core solder contains flux which is essential if you want to accomplish your soldering task neatly. Moreover, with the use of acid core solder, you can save money because you don’t need to buy a separate flux for smooth joints.
The purpose of flux is to clean any oxides and impurities over the surface of the metals to be soldered. Besides, when the acid core solder melts during soldering, you don’t need to apply flux separately because flux in the acid core solder flows with the molten solder.
Further, the acid core solder is excellent when you have solder pipes. Other than that, it is matchless when you have to solder metal sheets as they are thin in nature. In addition, the outer metal covering of solder flux can be of various metals, and each metal filler has its own uses and applications.
What are the advantages of acid core solder?
The significant advantage of acid core solder is it provides excellent strength to joints. You can use acid core solder for soldering any acid flux in its core which is the reason behind its versatility. Moreover, not a single soldering pro wants to use different solders for every other metal and project. That’s why they prefer this solder.
Whether it is metalwork, plumbing, vehicle production, and aircraft manufacturing, every work that involves metal can wield acid core solder. Moreover, if you are thinking of using acid core solder, then, believe me, you will make super smooth and seamless joints. The reason is the excellent cleaning and oxidation removal abilities of acid as a flux.
What are the drawbacks of acid core solder?
The major drawback of acid core solder, despite its excellent cleaning capabilities, is it tends to get corrosion because the flux waste will be going to conserve over the surface of the joints. Moreover, the debris reserve over the joints will make them brittle. Hence, it will not be good for your project unless you clean the left-behind flux residue.
To cope with this issue, you have to clear the joints using a wet cloth immediately. However, apply and rub a wet cloth when the joints cool down; otherwise, there is a chance you will burn yourself. Moreover, you can’t use acid core solder for soldering electronic circuit boards because cleaning residue will not be possible for you.
Rosin core solder
There is not a huge difference between the rosin core solder because the metals over the hollow core flux are mostly the same. The only difference is acid core solder contains acid as a flux in its core. On the other hand, rosin core solder has rosin flux inside the hollow of the filler metal wire.
Besides, the rosin flux inside the metal wire core is made of rosin, which is an oily fluid that comes out of the pine trees. Moreover, this fluid is then mixed with what we call flux. Rosin flux is excellent for removing grease and excessive oxides over the surface of metal surfaces but not comparable to acid flux.
But rosin flux doesn’t conserve over the joint, unlike acid flux which makes rosin core solder ideal for use in soldering electronic circuit boards. Circuit boards have many tiny wires and other components that don’t want to clean up, like acid core soldering because they will break in this way.
What are the advantages of rosin core solder?
Other than soldering circuit boards, you can also employ rosin core solder for soldering little wires. The reason is no residue leaves behind in the process. That’s why you don’t need to clean the flux after the soldering is done. Moreover, any excelling option for your soldering project doesn’t like the cleaning step of the acid core soldering process.
Like acid core solder, it also saves your time and money as you don’t need to buy dedicated flux. Moreover, you also have to apply separate flux first, which is not the case with rosin core solder, as you need to melt it and create a joint without applying flux independently. Further, there are different types of rosin core solders available in the market that have specific use. You have to buy the one which suits your job.
What are the drawbacks of rosin core solder?
Despite the wonderful benefits of using rosin core solder, there are many disadvantages of it as well. One of these drawbacks is you can only solder brass or copper with their utilization. That means you can’t use them for the majority of soldering projects because they involve joining metals other than copper or brass.
In addition to this, rosin core soldering releases unwanted fumes which aren’t good for your health. We know that these smokes are not lethal, but they can be very annoying for you, thus reducing your productivity. Therefore, we advise you to wear a respirator when soldering using rosin core solder. But if you can’t afford a respirator, you can use a mask as its alternative, which helps you overcome the respiration difficulty to a huge extent.
