Match each statement to the best option from the provided list. Options may be used more than once, or perhaps not at all.

1. A relatively low-density but high-strength metal that has excellent corrosion resistance as a cool solid, but not as a very hot solid or liquid.
2. The thermal conductivity of this metal is very low, making it difficult to machine since it doesn't effectively dissipate the heat produced at the cutting tool location.
3. The highest melting point pure metal.
4. A metal added to nickel-based superalloys to stabilize the precipitation of the secondary phase (gamma-prime) that strengthens such alloys.
5. A shiny metal that is completely brittle below 300 degrees C The pure metal with second-highest melting point.
6. A metal added to steels to drastically improve their corrosion resistance.
7. A metal whose oxide is more commonly produced (approximately 60x more by weight). The identity of this oxide mineral is rutile.
8. A metal that forms a very hard ceramic carbide for cutting tools and wear resistant coatings. Most of the annual extraction of this metal from the earth is utilized to form its carbide.
