a theoretical and practical StainlessSilver and StainlessCopper

I believe there exists a stainless silver and stainless copper but because stainless steel came along and is so cheap to manufacture and is not rare in occurrence of its ingredients/composition that we have failed to look for the Stainless-Silver and the Stainless-Copper.
Above I have assembled a premature theory of simply taking the analogy of Stainless Steel in that chromium is 2 elements to the left in the Chart to that of iron. So 2 elements to the left of silver is rhodium and 2 elements to the left of copper is cobalt.
So, can someone verify if a compound alloy mixture of silver with rhodium and some other elements but chiefly silver and rhodium produces a Stainless Silver.
Here is where theory runs against practice in that the theory maybe correct and that an alloy of silver and rhodium yields the **maximum stainless silver** but for the reality that rhodium is rare and so a Stainless Silver is going to be rare and expensive.
I would also like to discover a Stainless Copper which is more than 50% copper alloyed to something that makes it tarnish free such as stainless steel. Here again, I believe history just stopped looking for Stainless alloys once stainless steel took over the marketplace.
So if we do this premature theory analogy of 2 elements to the left of copper we end up with cobalt. Now cobalt, unlike rhodium is not rare. So if we mix copper of more than 50% copper with cobalt and other metals do we end up with a Stainless Copper.
Stainless Copper is a must in my consideration for every kitchen. I collect all of those old Revere ware copper clad pots of stainless steel because they are undoubtledy the fastest cook up of boiling water. Thin and copper transfers heat the fastest except silver. And copper looks pretty when shining.
So, is copper alloyed with cobalt and perhaps some other metals yield a Stainless Copper???
Is silver of 50% or more alloyed with rhodium and some other metals yield a Stainless Silver???
Is silver of 50% or more alloyed chiefly with chromium yield a Stainless Silver???
I want a stainless silver for flatware or silverware to use daily for eating because silver is a microbe-killer; kills bacteria and fungus etc. And silver transfers heat better than any other element so some expensive pots silver clad bottom is desireable.
I would gladly do the research on this except for the fact that I need extremely high temperatures. The last time I experimented in this I unluckily vaporized the gold. So I run the risk of vaporizing copper and silver et al.
But I suspect someone has already done much of the work above and may not have recognized the importance or has stopped short of realizing the Stainless quality that is desired.
Also, I need to verify whether the theory of 2 to the left is sufficient and why it works.
I need to verify by theory that these metal elements all have a Stainless alloy and why it works. And finally I need to verify in the theory that a Maximum point of Stainless or tarnish free exists for these metals since we can define stainless as the inverse of oxidation.
As I remarked earlier, there maybe a Stainless Silver and thus a maximum Stainless Silver but that its alloys are rare and expensive.

Hi, I am not quite sure whehter a stainless silver do exist. I guess you should verify what make copper rust. As to iron, It is the air and the water in the air. So we coat the iron to keep it from the air. Maybe the first step is to find the reason why copper or silver rust. And after all, the compostions you mentioned are too expensive for a chef .
