Lead Free Electrical Solder Buying Guide

If you want to join your pipes at home with the best lead free solder, you need to choose the product carefully. Go through all the features and benefits that the solder offers before putting your money on it. Here are a few functions and features that you could keep in mind when buying a lead-free solder.

Size Of The Solder

A standard size to go for when buying solder for pipes or electronics is 0.711 to 1.63 mm. This diameter is set as a standard size because the product melts in the right amount.

Since a solder that is wider in diameter melts in large amounts, it can be too overwhelming for a joint. On the other hand, for a solder that is too thin, the melted solder will be quite less in amount.

If the job at hand requires a large amount of solder, you can opt for the ones with a larger diameter. For bigger tasks, it’s also better if you go for a larger spool of solder. Basically, you have to select the diameter based on what you will be using the solder on.

Composition

When buying a lead-free solder, the composition of the product is one of the main things that you need to keep in mind.

Oftentimes, solder that has a composition involving tin and silver is lead-free. Solders usually have labels that state their lead additive status, along with other involved metals.

Products that are made of tin and lead melt quickly at 361-degrees Fahrenheit temperature. Therefore your work is completed much faster.

The composition of the solder affects other features such as the color of the product and the setting time. Therefore, checking the components the solder is made of is crucial at the buying stage.

Melt Point

A lower melting point between 360 and 370 degrees Fahrenheit is what you need to keep your eyes on. The lower the melting point, the easier it will be to add the solder in between the joints. You won’t need any high-maintenance heating guns to ensure that the solder melts smoothly.

Ease Of Use

Check whether the solder you are buying comes with flux or not. The solder has to be packed in with flux, so it’s better if the flux is added with your purchase.

Also, solder that comes wrapped in a spool is much easier to use than ones that don’t. So, the more user-friendly the solder is, the better.

Lead Free Solder Vs Lead Solder

Every product in the world has some advantages and disadvantages. While there are many advantages to lead-free solder, there are some disadvantages too.

Lead-free solder has one big advantage. They do not contain any toxins that will harm you. So you can add the product to your water pipes and in-house plumbing.

But, lead-free solder also has a higher melting point than the solders that have lead in them. Therefore, lead-free solders are a bit harder to use. You need more heat and time to melt lead-free solder properly.

Because the product is tough to melt down smoothly, beginners sometimes face a lot of trouble using lead free solder.

Lead Solder

Using lead-tin solder is much easier than using lead-free solder. Iron regains its working temperature much faster when lead solder is used.

Because they have a lower melting point, lead solders are easier to melt. Also, the flow of the product is manageable and smooth.

Lead-tin solders have little to no internal flaws after cooling down. Tin whiskers can be avoided using this kind of solder as well. They have a shock-resistant feature, which can be beneficial as well.

But, one thing you must consider is that these solders are not good for your health. You should definitely avoid lead-tin solders if you plan on using the product for water pipes.
