Check out this article. I copied it from NWT Precious Metals Monthly:
Germanium Creates Tarnish-Free Silver Alloy
Germanium, alloyed with silver, is stronger and better resists tarnish than sterling silver, and may replace sterling silver as the standard for wrought silver items. This claim is made by a company called Argentium International, which owns the patent and is marketing the metal to companies using sterling silver now. The germanium attracts oxygen and migrates it to the outer layer of any item fashioned with the alloy, which is being called argentium. Tarnish in sterling is the result of oxygen combining with the copper that composes 7.5% of the classic silver alloy. Adding germanium enables less copper to be used in creating champagne buckets and the like. Fire stain darkening as a result of heating the metals to form sterling is also eliminated in the new alloy.

THIS alloy, yes, why not?
Did you think all alloys were common knowledge from birth?
Smile, I don't mean to pick on you Pensil, but "why not?"
If you mean....it just happened by accident, no. I am sure they were testing all different new kinds of alloys .... possibly not even related to common sterling purposes. Hard to say from just reading this article.
I wonder if this alloy though retards the antibacterial property of traditional sterling silver. |

Might be kind of neat to barter in "Pounds Argentium International", eh what, Old Bean.
I wonder when bars and rounds will be offered on the "free" market?
Maybe that will be the composition of the new Amero ... |

I don't see any practical advantage in making non-circulating bars or rounds out of it. That is if you don't plan on a thousand years or more of storage for them. I wonder if the alloy would throw-off an acid test? Interesting stuff though and it can only help make silver more popular in the future. |

Exactly!!
There's always the "uniqueness" factor in collector "art" bars and rounds.
Plus it's nice to be diversified, to a degree.
Not to mention .925 Ag is still .925 Ag.
It all depends on the spread (premium). |

Jewelry springs to mind as an application, I was just reading though that some germanium compounds can be irritating to skin etc so I wonder if that might be an issue in some cases. Interestingly it sounds like germanium is generally more expensive than silver (recent prices in the $1300-1400/kg range, around $40-43.50 a troy oz)

| I wish my silver pitcher and dishes were tarnish free. Polishing them sucks. Sounds like a great marketing idea for silver plated dishes and other items. I'd think the art bar and investment market would be more interested in pure silver. |
