Erik has the most correct answer, so far. Titanium is NOT commonly used as an additive to silver and the Rhenium, Ruthenium etc would only be used for alloys for very particular usage, e.g pen knibs for fountain pens - this is not a growth industry, however!
All these additives are metallic ELEMENTS, by the way, not alloys. An alloy is the RESULT of mixing two or more elements.
Just in case there is any further confusion Nickel Silver contains NO SILVER. It is a copper-nickel alloy made to replace the silver coinage that existed in Britain prior to 1921.
