What s the silver stuff at the ends of home theater speaker wire?

After wear and tare, the silver part snapped off and I had to use wire cutters to get more wire to plug into the back of my home theater. Is it real silver coated over top of copper wire? And is there a place I can buy it? I m assuming it helps with high frequency.

It's solder, which used to be a mixture of tin and lead. (Modern solder doesn't have lead.)

It's there to hold the strands of the wire together so fine wires don't fray, and cause a short circuit. As long as you're careful with your wiring, you don't need to replace the tinning on your speaker wires. It has no effect on the sound.

It is solder to prevent the strands from fraying. It is not needed. I would just twist the bare ends and stick it in the hole.

Is there a place to buy it and you think it helps with high frequencies? Just forget about that stuff okay? Even these are just cables it is not quite that easy. I've been following the audiophile community and there are arguments that ends friendships and leads to death threats over speaker wires.

It's WIRE!

It may have been tinned with solder, but it's still Wire.

Silver is not used in such low-cost applications.
What was in the part that broke off would be about
95% tin and 5% something else that's cheap.

It was there for only one reason:
To hold the strands of the wire together,

If you want the end re-tinned,
find someone who knows how to solder and have it done,
but for all practical purposes, it would be a waste of time.

It has NO effect on ANY audio frequency.

If you want to you can recoat the wire yourself using solder and a soldering iron...You can get silver solder if you want to it's a little more expensive and only about 1% silver but it is available......You can also get gold plated pins that you attach to the ends of the speaker wire that will also work....but as has been pointed out its not absolutely necessary

If it's old it is likely near Eutectic lead-tin solder 37% lead. don't stick it in your mouth or your fingers after touching it. If its new it is almost for sure a lead free more environmentally friendly compound - still don't lick it you don't need to ingest heavy metals.
it isn't really necessary as long as you make certain no spurious strands of wire short to the other wire.

Its called silver solder. - keeps the wire strands from raveling and shorting and generally being a pain to deal with. The process is called tinning, and is something you can do with your own wire installations too.
