'Serinium' proprietary alloy??? 1

[WKTaylor]

Anyone have a clue as to the composition of the metal alloy 'Serinium'? Curiosity has the best of me...

'Serinium' is being marketed by a jewelry manufacturer as the replacement for platinum, gold, etc... used in wedding bands, etc.

NO OBVIOUS clue 'on-line' as to what it is made from...

They reference their patent# here.

https://patents.google.com/patent/US9289037B2/en

Hardened cobalt alloys for forming jewelry, including finger rings as well as methods and processes for producing such alloys. In one illustrative embodiment, such an alloy can contain cobalt in an amount of from about 35 wt % to about 65 wt %, in combination with chromium in an amount of from about 16% wt to about 32 wt %, and molybdenum in an amount of from about 8 wt % to about 31 wt %. Aluminum, silicon, boron, titanium, and other hardness enhancing materials may also be present.

I always thought one of the reasons for using gold & silver in jewelry is that they are soft and easily hand worked but one of the claims for serinium is that it is "ultra-hard".

Thanks MJ... thanks!

Cobalt alloy, huhhhh... I guess they have a 'gimmick'. No particularly valuable metal for high-end jewelry... just 'bright/durable'.

With the variable constituency of metals within the alloy, it sounds like AMS5380 or AMS5537 or AMS5759, etc casting/ring/tube/bar alloys... primarily for high strength bearings at high temperatures... adapted for 'jewelry'... possibly by specialized heat treatment(s).

Had I been allowed to I probably would have selected a Cobalt wedding band with the goal of it getting less scratched over time.

But I wasn't, so now I have a scratched Platinum ring. Fine with me.

look up the Apple patents on age hardening gold alloys.
hose are real interesting.

Visit Tiffany stores and you cant help eavesdropping customer requests for ring band in exotic metals like Rhodium, Cobalt ( very common) and a few complex mixes of different metals. Wonder,,how the stores caters to such requirements. But then customer is King.

Ed...

'look up the Apple patents on age hardening gold alloys.'

I assume that Apple products use a lot of gold-alloys for micro-electronics, electrical contacts, etc [plated or vapor deposited?]... so that almost makes sense... but still... sounds like a way to force competitors to back away from a legal fight.

Apple are speculative patent hoarders, not an unknown practice for large industrial corporations. Apple does it to litigiously bully its competitors.
.
The Serinium web page advertises its alloy as being 'very hard' as well as being 'easier than any other gold alloy to cut off in an emergency.' So which is it?

Carbon fiber rings are a thing, too.

 

[EdStainless]

The Apple patents are for the alloys used in smart watch cases.
And they do make these.
It is interesting stuff, it is an age hardening alloy.
Forma and machine it while med strength and then age to high strength.

The patent describes the hardened alloys being useful less for scratch resistance, and more for the ability to be broken in two in "emergency situations".

Gold and silver don't tend to corrode; I suppose malleability is a side effect of that. It also means they can be accumulated as wealth over generations, unlike iron.

There have been some tungsten carbide jewelry, particularly rings, but a lot of comments from people who had them reported they shattered, an advantage in the case swelling of the finger threatens strangulation of the digit.

 

[EdStainless]

6 of one half a dozen of the other, I have crushed a gold rink onto my finger and had to saw it off.
Breaking might have been preferable.

More or less Vitalium. Been around many decades , very common in medical implants. Also as a very old alloy for hot stage turbine blade and vanes.
