Can you use regular solder on copper?
Copper pipes and other copper parts can be soldered using various metals with low melting points. Traditionally, lead alloys have been used for soldering copper, but these have fallen from favor in recent years due to lead poisoning concerns. Today, copper water pipes are soldered with lead-free flux and silver alloys. via
Do you need flux to solder copper wire?
Strong metals such as brass and copper will require a synthetic acid flux in order to be soldered. This will remove not only oxidation but also corrosion and other residues that build up on these metals. via
Does solder stick to copper wire?
Stay away from lead-free solder; use 60/40 Tin/Lead solder. Use copper wire. (I've rarely seen solder not bond to copper wire; what are you using?) Simultaneously heat both parts that are being soldered. via
Can I use silver solder on copper?
The amount of zinc in a metal lowers the melting point, that's why brass melts at a lower temperature than pure copper. As you can see in the chart above, you can use any silver solder on copper or brass metal, but solder flow points vary between vendors so always check the flow points of the solders you choose to use. via
How do you hide solder on copper? (video)
What can I use instead of solder?
3 Effective Alternatives to Soldering Electronics
Can I use lemon juice as flux?
Cut six lemons in half with a kitchen knife. Squeeze the juice from a lemon into the strainer. Stir the juice in the container for 10 seconds with the wooden spoon. The citric acid flux you have made can now be used to prepare metal for soldering. via
Does Vaseline work as flux?
Can You Use Vaseline as Flux? Yes, Vaseline works just as well as commercial flux, and you can even buy a generic brand. Petroleum jelly is primarily made from waxes and mineral oils so that it won't corrode your components. Plus, it cleans away the gunk and eliminates metal oxides that could compromise your bond. via
Why does solder not stick to wire?
If you let the solder sit on the iron, the flux quickly boils off (the fumes are from flux, not the lead). And without flux, soldering becomes almost impossible. Flux removes oxidation from metals, and it's crucial because solder won't stick to oxidized metals, and metals oxidize very quickly at soldering temperatures. via
Does solder wire expire?
Flux cored solder wire has a limited shelf life determined by the alloy used in the wire. For alloys containing more than 70% lead, the shelf life is two years from date of manufacture. Other alloys have a shelf life of three years from date of manufacture. via
What material does solder not stick to?
Solder simply will not adhere to dirty or oxidized metal surfaces. Clean any flat surfaces which are to be soldered with steel wool, a file, emery cloth, etc. It's important to take time to clean the surface thoroughly. Scrape any wire to be soldered with the back of a knife or any flat piece of metal (Fig. via
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. via
Why is my solder not shiny?
Dull (non-shiny) solder joints are usually the effect of coarse grain structure in the solid solder joint (though there can be other causes). The more slowly a joint cools, the coarser the grain growth and, conversely, the faster the joint cools, the finer the grain growth and the shinier the joint. via
Are there 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. via
Do plumbers use silver solder?
Oatey® Silver Lead Free Plumbing Wire Solder is a silver bearing wire solder designed for plumbing and potable water line applications. Safe Flo Silver Lead Free Solder is also effective on stainless steel, brass alloys, chrome alloys, galvanized steel and cast iron piping. via
Do you need flux to silver solder copper?
When you're soldering you should always use flux.
If you're using silver solder – that is, solder with 45 percent silver or higher – to connect copper to steel you must always use an acid-based flux. via
Why is the solder not sticking to copper pipe?
If the solder is beading up or running down the pipe, you have a dirty fitting. Just as Vic says use clean fine grit sandpaper or emery cloth. Clean both surfaces, spread flux as soon as you clean them. Also clean and flux joint after you fit them together. via
What is the best solder for copper pipe?
The Best Solder Is Safe Solder
The new lead-free 95/5 solder, 95% tin 5% antimony, has a lower viscosity than 50/50. That means it flows more quickly when molten. It flows so quickly that it can flow right through the joint while it is being applied leaving a gap at the top of the joint. via
What solder do you use for copper to brass?
If you have done any electronic soldering you probably used a lead based solder. This is fine for soldering electronic components together but isn't really strong enough, nor does it give a great bond, to copper and brass. Your best option is to use a silver solder. via
Can you get copper Coloured solder?
Using the copper color-match wire solder, the solder seams are much less visible and have a color that almost exactly matches the rest of the wire. With proper finishing, they're nearly invisible seams. This copper wire solder is 93 percent copper, but it's 18-gauge and pretty hard. via
Can you use superglue instead of solder?
super glue (cyanoacrylate glue) is a good insulator. i have heard of people using it to provide extra hold on wire wrap boards. its not doing the job of solder though, its not providing the electrical connection but rather just keeping it from coming unwrapped. via
Can I use aluminum foil instead of solder?
Is there a good way to solder a wire to a piece of aluminum foil without the solder beading up and not sticking? No. You cannot solder to aluminum unless you have aluminum wire and aluminum soler. via
Can you use a paperclip as solder?
Apparently paperclips are also made of galvanised steel as a rule, so there may be a connection here. Other metals such as aluminium or regular steel can be soldered, but require special solder and flux and may need stronger equipment. via
How do you make homemade flux? (video)
Is flux and soldering paste the same?
While the main use of solder paste flux is in the creation of solder paste, it is also sold directly as a gel or tacky flux. Solder paste flux can also act as a temporary adhesive. Once mixed, solder paste is most commonly used in a stencil-printing process. via
How do you make solder paste at home?
Can you braze without flux?
You can join copper to copper without flux, by using a brazing filler metal specially formulated for the job, such as Handy & Harman's Sil-Fos or Fos-Flo 7. (The phosphorus in these alloys acts as a fluxing agent on copper.) via
What metals can you soft solder?
Soft Soldering is a method of joining metals with a Eutectic Tin/Lead Alloy. The heat source is often an Electric Soldering Iron but copper 'irons' heated with a gas torch may be needed for larger work. Metals including copper, brass, lead, tin (inc. via
Do I need flux if I use rosin core solder?
You want onlyRosin Core Solder for soldering electronics. The rosin acts as flux (A substance that helps prevent oxidation and promotes bonding). Flux is essential, but the wrong kind of flux will destroy your project. via
What temperature should I solder wire?
600°- 650°F (316°- 343°C) is a good place to start for lead-based solder and 650°- 700°F (343°- 371°C) for lead-free solder. You want the tip hot enough to melt the solder efficiency, but excess heat can damage components as the heat travels along the leads, and it will reduce the lifespan of the soldering tip. via
Is it OK to solder electrical wires?
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. Never use solder that contains acid, which can damage the wire or its insulation. Acid-core solder is intended for use in plumbing applications. via
Can you use too much flux when soldering?
Re: Too much flux? The flux left inside will wash out. The flux (which is acid) left on the outside of the pipe can continue to corrode. Wiping joints after soldering should remove the excess. via
