#8: Rhenium

Type of Metal:

This not well-known metal discovered in 1925 is one of the densest metals and has the third highest melting point (5,766.8°F).

What it’s used for:

As one of the rarest metals, it can withstand intense conditions, and has been used in high-temperature turbine engines. It’s also added to nickel-based super alloys to improve their temperature strength. It’s also found in filaments, electrical contact material and thermocouples.

Where it comes from:

Rhenium is a by-product of molybdenum, which is essentially a by-product of copper mining. Chile, Kazakhstan and the United States led world production of this metal in 2009.

So how much is it worth?

By the beginning of 2013, the rhenium market had experienced 3 years of relative calm after considerable sharp fluctuation from the end of 2006 to 2009. Since the end of 2009 the spot price has remained below $5,000/kg and was being quoted between $3,500/kg and $3,700/kg in January 2013.

Is it recyclable?

Unlike over 1/3 of all metals, rhenium has actually seem a rise in recycling rates (although less than a quarter of it found in jet engines is second-hand). This has helped by it’s low price point, and the fact that it is easy to find and extract from scrap jet engines.
