Basically all metals can be soldered, but we are looking for a low melting point soft solder and a flux. With the soft solders and a zinc chloride flux (most common), these metals will bond very easily: copper, tin, and brass. These metals will NOT bond: Iron, stainless steel, steel, and aluminum.

Hereof, what wire can be used for soldering?

Inside the solder core is a material known as flux which helps improve electrical contact and its mechanical strength. 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.

Also, what metals can be soldered together? Metals that can be soldered include gold, silver, copper, brass, and iron. The filler, called solder, melts. When it solidifies, it is bonded to the metal parts and joins them. The bond is not as strong as brazed joint or welded one.

Likewise, people ask, can you solder any wire?

The most secure and durable way to splice two wires together is to solder them. Period. Use nothing but 60-40 rosin-core solder intended for electrical wiring. You'll also need some PVC shrink tube.

What kind of solder do you use for copper wire?

The best solder to use for tinning stranded copper wire is electrical-grade rosin-core solder. This is an acid-free solder that contains a flux in the core of the solder.

Can you solder without flux?

Bear in mind though, most common solder wire is rosin-core, it has one or more cores of flux inside of it. The kind of solder plumbers use has no flux because they apply the flux externally. So you could solder with that solder. At low heat the solder might not melt fast enough, and a cold solder joint may result.

What can I use if I don't have soldering wire?

Smith explains that soldering two wires together doesn't even require a soldering tool, but if you need to do some more intricate work, steel is the best choice for an impromptu tool. Steel wire, screwdrivers, nails, and Alan wrenches are all potential tools for your emergency soldering.

Can I use glue instead of solder?

As others have said super glue is not conductive. You can buy conductive adhesive which is used when normal soldering is not practical. It is not as good as solder for many reasons but it can be very useful if soldering can not be done normally.

What can be used in place of solder?

Wire-wrapping is a substitute for soldering but wire-wrap supplies can get very expensive unless you buy in very large volumes or happen to find a surplus deal. You could also crimp the wires together. There are terminals called butt splices. You could insert multiple wires into the terminal and then crimp.

What are the types of soldering?


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.

Do I need flux to solder wires?

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.

How do you wire without soldering?

What you need: a roll of electrical tape and two wires whose ends have been twisted together. First, lay the twisted part of the wires onto a strip of electrical tape. Wrap the tape around the wires tightly 5-6 times, making sure to cover up all the wire. Give your connection a tug to make sure it is strong.

What is solder wire made of?

Lead-free soldering wire is comprised of various combinations of tin, copper, silver and antimony. Pure tin wire has the highest melting point of 449 degrees. Other combinations of metals melt in a range between 419 and 441 degrees. Soldering iron tips are made of copper core plated with iron.

Is it safe to solder house wiring?

No, today they are not common but when the world was gentler and slower paced the practice of solder joining wires was commonplace everywhere. The reasons these joints are not common today are many. Here are a few of them: It really takes a long time and a lot of skill to do wire solder joints properly.

Can you use electrical tape instead of soldering?


Or if this is really the only time you would ever use it, have someone with a soldering iron solder the wires for you as a favor. Solder does both these things. Electrical tape only does the latter. Therefore, no, electrical tape is not a substitute for soldering.

Why solder will not stick?

A classic reason solder won't stick to something is because you're not getting it hot enough. Touch some solder on it, and it should melt almost instantly. Put a nice little blob of solder on the tip of the iron. Press the blob of solder into the metal to be soldered.

What metals does solder not stick to?

Basically all metals can be soldered, but we are looking for a low melting point soft solder and a flux. With the soft solders and a zinc chloride flux (most common), these metals will bond very easily: copper, tin, and brass. These metals will NOT bond: Iron, stainless steel, steel, and aluminum.

Can you weld aluminum to steel?

You can weld aluminum to most other metals relatively easily via adhesive bonding or mechanical fastening. However, in order to weld aluminum to steel, special techniques are required. To avoid this, you must isolate the other metal from the molten aluminum during the arc welding process.

Can aluminum be soldered to steel?

Soldering aluminum to other metals (steel, galvanized steel, copper, brass, stainless, etc.) is also done, but with some difficulty since the joint design must allow for differential thermal expansion and many fluxes do not work for both metals.

Does solder stick to steel?


Soldering, Brazing, and Welding Tips. Soldering with a propane torch is the easiest way to join copper and brass. You can even use solder to join copper or brass to stainless steel, you just need the proper flux. Do not use electrical or jeweler's solder because these often contain lead or cadmium.

What is Tinning the bit?

Tinning is the process of thinly coating sheets of wrought iron or steel with tin, and the resulting product is known as tinplate. While once more widely used, the primary use of tinplate now is the manufacture of tin cans.

Can you solder 2 pieces of metal together?

You can't really join metals with adhesive—not with ordinary glue, anyway. But you can join them by melting them together in a process known as welding. The basic idea is simple: you apply a source of heat to melt the two metals so they fuse and form a secure joint.
