    Tungsten HP 4-1

     

    Fellow ringers, my two year journey to work with tungsten has finally paid off.  From acquiring the material, to Jon at TRL being gracious enough to work it, to shipping to crafting.  It is finally done.  Jon coiled and hot cut a set of rings for me, that turn out to be about 16g 11/32.  You can see from the pic that the hot cutting has left an iridescence to the rings, like the cars that change color from purple to gold to green as they drive by.  Very pretty but also dark because of the metal's natural dark grey finish.  They are somewhat brittle, and much care must be taken with opening/closing the rings; they are tough.  A little hand pain and some chewed up pliers later, HP 4-1 seemed the best bet for the bracelet.  Thanks again Jon for all your hard work seeing this come to fruition.

  2. Hey folks, the tungsten samples from TRL are in and I have included some pics. The Lord himself did this first set of work, and did explain that the springback was massive and he had to hot roll the Tungsten to get the test coil pictured. There is a close-up of a fractured end of the Tungsten, which is due to the extreme pressure needed to cold work the metal; trying to cut using a pair of snips also results in fracture. I did cut off a single ring using a Dremel cut-off wheel, but it did leave a wde kerf. I ordered some .005in cut-off wheels (separating disks) and will try those out once I return from a trip. More to follow.

  4. Jon,

    Thanks again for trying to work the Tungsten, I know it was a pain to work. I actually ordered the 15-16ga from Amazon, from a website called smallparts.com. They do have other sizes of tungsten wire, but the prices are quite varied. The wire I sent you is .060in diameter, and it was sold in a pack of ten 60" strightened lengths for $28. The advertised purity is 99.95%.

    However, loooking at the website this morning, the .060 is not available in a set of ten, and a set of five wires is now over $50. An example of a pricing anomaly:

    .050 set of ten 60" lengths: $58.42

    .051 set of ten 60" lengths: $126.71

    Link to the smallparts site: http://www.smallparts.com/small-parts-tungsten-wire-straightened/dp/B003R5029Y/ref=sr_1_1?sr=1-1&qid=1328539101

    I did see that they do not ship the wire to Canada, so Jon, if you want some, let me know and I can send you some. i will be ordering more in smaller diameters for future projects.


  5. I just mailed 50 feet (10x lengths of five foot tungsten) of .061in diameter to the Lord to see if they can do anything with it. The material cost me about $29 at amazon and other gauges are available as well from Small Parts but the pricing is odd. For example, while a ten pack of the .061 is $29, a ten pack of .058 is $162. A link to their site is posted here: http://www.smallpart...&qid=1326908384

    The "Lord" himself has made some test rings and a coil from the tungsten rod I sent, and it has been mailed. Once it arrives I will post pics and start playing with the material.


  6. From what I have read, pure Tungsten is workable, about the same difficulty as steel. When dealing with alloys of tungsten or impurities is does get very brittle. I have tried hand bending some of the .060" Tungsten wire I got in, and it is tough. I have snapped a couple of pieces and I can see how it can splinter. I am hoping that someone at TRL has at least made coils before or would be willing to try it. I am certainly willing to send them some metal if they are willing to try it.
