Has anyone looked into buying high purity tungsten? I think it would be neat to have a nice weighty chunk of the stuff around. It has the highest melting point, lowest coefficient of expansion and highest tensile strength of any pure metallic element, plus it's one of the densest non-precious metals.
There is one guy on ebay selling 1/8"-1" dia, .9995 tungsten rods cut to length for 6.63 an ounce (guessing he means avoirdupois) which works out to 108 something a pound. A lot of what came up on google was either large volume chinese suppliers or high-priced element sample type outfits. One place, espi metals, does small orders of rods, plate, etc. but you have to contact them for a quote. I'm not expecting to pay very close to spot but from what I've read it's been closer to 10 a lb than 100 recently so I'm hoping someone's selling to small-timers for cheaper than that ebay guy.
Also, does anyone know of a kitco style site that does graphs for tungsten spot prices? Metalprices.com wants a paid account and I haven't found any other places.

Buy worn out Tungsten cutting bits. Sometimes available on ebay. Some are shaped like a flat bar but watch the sharp edge.
I'd love to see how they melt this stuff when it's made. My guess is some type of electric arc furnace with an inert gas environment.
Those 1/8" "rods" you see are probabaly used in GTAW welding as a non-consumable electrode. Pretty cheap price which suggests it was "liberated" from a job site. It is used in GTAW welding and the arc is so hot it melts chrome steel in less than a second without consuming the tungsten. Pretty amazing metal. |
