Au=gold,Si=silicon. Brazing alloy.

Thanks, I was not aware of the Au/Si solder. Thought he meant silver. Found this with google.
"gold plating of silica nanoparticles for use in composite solders"

 

[qst42know]

It melts at 685 F so technically it is a solder not a braze.

THANKS for this list! Makes it much simpler to show my crew what items to watch for.

I've put it into a .doc form (single page, "suitable for framing" - maybe it will help others...

I see headlamp in the list under automotive, does anyone have any examples.

One thing which has become a profitable stream of refining which, for years was never discussed, is crematory scrap. It is a high yield scrap with Gold and Palladium. When a body in the USA is cremated all of the metal parts are screened out. That is titanium knees, pacemakers, and all dental work.

Here in the US a lot of refiners go after it but in South America where @arthur kierski is located it is often discarded.

reflectors of old premium cars were rhodium plated to improve reflection

I think the dead are deprived of dental gold even before entering the oven....

I can list at least a page full of refiners in the USA that are getting it post oven. If they know the deceased had a pacemaker, that is removed before because they explode in the oven.

very sensitive topic...
but it seems to me that the gold of the dead should belong to their heirs.

I tend to agree, but the laws and ways to do things are different around the world I guess.
But this is probably mostly what is in the body, like stents, dental and such things, not jewelry.

I think many would be surprised where precious metals are used in what appears to be totally unrelated industries and the people who know , because they sell them , where those metals go aren’t likely to tell others as they probably also get the scrap.
I told of one I knew which was silver targets for use in the window industry and who would have guessed that industry was a big user of silver.
I have suggested before to talk to everyone you know about what they do and what they make and see if there’s a possibility of PM use.

very sensitive.... there are a few states (I believe I was told 4 states) that say the undertaker cannot profit from the sale of the remains. The way the refiners get around it is they melt the lot and figure out what it is worth and call the client and ask them what charity they want the proceeds to go to in their name. Then they take the tax deduction.

There are as many techniques in creative accounting as there are techniques for different scrap refining.

Here in Brazil,i never thought of this.I think it is an idea that can not be discarded.
