Question: Which Solder Wire Is Best?

What flux percentage is required for wire solder?

Flux percent by weight will vary from 0.5% to 3% in solder wires and higher percentages will leave more visible flux residue.

Less flux in the wire, less flux residues, however you need a good percentage to enable ease of soldering.

Usually 1, 2 or 3 % flux is best with 0.5% being more difficult to use by operators..

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.

Is it OK to solder electrical wires?

The reason is that solder is a very good electrical connection, but a very weak mechanical one. Copper (or aluminum) alone can bend, flex, and even stretch a bit without any damage, so it’s suitable for things that move around a bit. Solder is very brittle and will crack and break if you try to flex it.

Does solder increase resistance?

Tin (the main component of most solder) has about 5 times the resistance of copper. As such, when used in high current applications (think a battery lead), that resistance can lead to heat. … The resistance creates heat at the joint, which melts the solder, which increases the resistance until it fails altogether.

Do I need flux to solder?

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 the difference between 60 40 and 63 37 solder?

60/40 does have a “mushy” state, whereas 63/37 is eutectic and goes “instantly” from liquid to solid. But 60/40 has a small mushy range and it’s usually “close enough”. I’ve noticed a bigger difference with lead-free solder or different flux.

What is the best type of solder?

For electronics soldering, the most commonly used type is lead-free rosin core solder. This type of solder is usually made up of a Tin/Copper alloy. You can also use leaded 60/40 (60% tin, 40% lead) rosin core solder but it’s becoming less popular due to health concerns.

What is the best solder for automotive wiring?

Use rosin core solder; the center contains flux that cleans the surface of the wire to be soldered. Solder is often a combination of mixed alloys. Automotive applications use 60/40, containing 60% tin and 40% lead.

Is it better to crimp or solder?

Crimping offers stronger, more reliable connections than soldering. Soldering uses heated metal to join the cable to the connector. Over time, this filler metal will degrade, which may cause the connection to fail. Most electricians will agree that crimping is also easier than soldering.

Why is solder so expensive?

Small diameter solder always costs more forma given weight. Unfortunately with modern components you need to buy very small diameter solder for hand soldering. Yes, as the diameter decreases the price definitely increase.

Why is my solder not shiny?

The flux is important in cleaning the surface you are putting solder to and is activated by heat. If it gets all burnt-up on the iron, you will notice the solder not look as shiny and smooth the more it gets burnt away.

Is plumbing solder the same as 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.

How thick should Solder be?

You’ll use the 0.032″ for most work, but the thick stuff (0.062″) comes in handy for soldering larger stranded wires — and the fine solder (0.020″) is useful for delicate soldering jobs on small components. Solder is about 40 percent lead, and as you probably know, lead poisoning is a very real health hazard.

What is the difference between silver solder and regular solder?

Silver solder usually refers to a stronger solder used for mechanical joins (compared to lead solder which is soft and relatively weak). However, silver solder has a higher melting temperature, which means the parts have to be heated to a higher temperature to make it work.
