Harris Safety-Silv 56% 1/16 Silver Solder Brazing Alloy 1 Troy Ounce, 75310 5631

Have used this Harris silver solder for years. Perfect results every time

At first I could not get the tiny jewelry parts hot enough to melt the thick solder without destroying the part. Then I hammered the end of solder flat and it worked fine. Using butane pencil torch.

I use silver solder a lot where I work. To join carbide to steel, steel to steel, brass to steel, well lets just say if you need two metals joined I know how to do that. So I am very good at working with all silver solder products. I used this at home to give a keychain skull a silver coat. I also used to mend some old broken jewelry. with the 56%silver this is not the ideal solder for steels or brass or copper. Just because its costly. If the silver color is not needed I would use a solder with a lower silver content. The most important things to know are the flux and the temp the target metal must be to get this product to flow across the desired area. If the metal that you wish the silver solder to flow to is too cool in temp, the solder will bead up. This is because you melted the solder with out the target metal heated to the melting point of the solder. With the right flux and preheated metal you will get the solder to flow out easy. One this you should know about the flux is try to keep it free of contaminates such as oil, dirt, soot or oxides. This can cause the solder not to bond the the target metals, even thou it may seem to be holding, they can detach with a few pounds of force.

Does a great job brazing copper or dissimilar metals. Has a lower melting point that 15% Sil-Fos and flows more like soft solder. My go to for brass to copper brazing jobs. Flux as needed.

Works good, must use Flux that is for it

Used this with propane torch on small crack in cast Iron. Clean well, apply generous amount of Stay-Silv flux, get it to a dull red heat and apply the silver solder.

Used to braze a stainless line to a hard copper elbow. Used with black flux, worked perfectly. I used oxy-acetylene with a reducing flame. Focused on the stainless but the copper was red. Flowed easily uphill into an imperfect joint and sealed on the first attempt.

Fantastic price

Orthodontic

For what I needed it has to high of a melting point.
