Here’s some brass. Hard to get it to show in the photo but there is quite a bit of yellow in the flame
The photos probably look the same
If you grab known bit of each and test you’ll see it much more clearly.

Can't remember seeing one in the last one I pulled apart.

This was a desktop that I had built for cad work about 6-7 years ago, it's Ø28mm . It was a good box until something on the motherboard dropped it's lunch.

If anyone is looking for a small project...

On the left is a genuine replacement face for a Thor #1 copper face hammer.
On the right is the middle out of a computer heatsink...

Thank you Steve,
That is an excellent piece of info. I have a copper faced hammer on the back burner and and an old computer tower to junk.

Hopefully it’s got one in it.
I messaged a colleague at work earlier as I’m pretty sure they have a few old machines that will get scrapped as soon as we’re back on site properly.
Apparently Intel stopped using copper cored heat sinks a couple of years ago.

OOps! I might change my mind there. I found this at Safety Australia.

" Beryllium (CAS 7440-41-7) is a grey metal that is found in nature as a mineral with silica or with aluminium and silica. Beryllium exists as a free metal or in an ionic state (Be[II]).

Beryllium metal is used:

in structural material in space technology
as an additive of rocket fuels
as a moderator and reflector in nuclear reactors
in navigational systems
in manufacturing

Beryllium hydroxide is the feedstock for production of beryllium oxides, metal and copper beryllium master alloy.

Beryllium oxide is used in the manufacturing of:

specialty electrical and high-technology ceramics, for example resistor cores
special glass
electronic heat sinks
electron and laser tubes
electrical insulators
electronic components, for example circuit chip carriers
nuclear moderators and fuels
military vehicle armour
rocket nozzles
laser components. "

Our thermal imaging camera at work uses a Beryllium window for the lens of the ir camera.

Beryllium, being a very light metal allows IR to pass through it.
