Here are some ferrules I am working on.
They are cut from sheet metal scraps that happened to be the right gauge to use for this project.
These ferrules are brazed in the forge. The copper wire that's going through the inside of the ferrule and is clamped at the edges will serve as the filler material kind of like soldering or sweating a copper pipe.
They are heated up to a dull red at first and then borax is sprinkled on to melt and protect the metal from oxidation and help allow the copper to flow into the joint.
The freshly brazed pieces are incredibly messy and full of melted borax, over flown copper, and wire fused on.
I take them and put them in a pot of wire and boil them for about 15 minutes and that will dissolve the borax flux so I can then file the excess off or just grind it.
The ferrules were then rubbed with a cheap medium/coarse grit sharpening stone in a bucket of water to give them a smooth finish before I put them into my small electric furnace to heat them up to a dull red at 814 degrees centigrade (1497 degrees Fahrenheit) and simply let them cool slowly in the machine over night.
The next step is to true them up with a mandrel so they're totally round on the inside.
A ferrule is a metal band that goes around a wooden handle so it doesn't break or split after the tang of a tool is driven in.

The base metal is steel, it has a higher melting point than copper. The whole thing glows a yellow colour, which is probably 1,085 degrees centigrade (1,984 degrees Fahrenheit)
So, no, it's not going to melt.
Also I probably will give them another touch up with medium or fine abrasive to bring it back to the plain grey steel finish.
