Valadium is a trademarked stainless steel used for making class or military rings. The metal contains nickel, has a silver tone, and will last for years.
A lot of class rings are made of a substance referred to as valadium. Valadium is steel, and does not hold it's value like a precious metal. Many class rings that are made of valadium are worth $25-$35.
Valadium's unique properties offer a hyperallergic solution for the wearer, as well as a cost effective alternative to common white colored precious metal alloys such as sterling silver and white gold
Valadium is not worth much at all.
Valadium. It is a high-grade steel.
VAL is for Valadium. This comes in white or yellow to resemble gold. It is an economical alternative to gold. It's also stronger so it won't scratch as easily.
Generally, carbon and hydrogen make up 90% of the elements in petroleum. The other elements are nitrogen, oxygen, sulfur and very minor amounts of metals. These metals are usually called trace metals, and include valadium, nickel and iron. Please remember that oil is a very complex mixture of hydrocarbon compounds, so to fully description of an oil sample, these compounds need to be identified. See link.
They're both essentially stainless steel. You'd have to be more specific about what you mean by "better" for any distinction to be drawn... harder, higher conductivity, higher melting point, greater chemical resistance, or whatever. I'm guessing you're looking at class rings, since that's what those two alloys are mostly used for, and neither of them has any intrinsic value (well, the marginal couple of bucks a pound for scrap iron). So get whichever one you like the color of best.
