Write me down for 2 pounds of bismuth then!

If prices are the same i prefer shot - i'll be melting it anyway, but shot would be easier to weigh and partition.

I hope it's not out of place to post in this thread but for anyone interested in tungsten in a known size primarily for demonstration of it high density I recommend looking at: https: forward slash forward slash www dot mi-techmetals dot com/cart/

I have no affiliation but bought a couple chunks from them about a year ago. *It is not 100% tungsten but is 90%+ with a density of 17g/cc.

I know from experience that the following two part numbers have have the masses listed below

F17B1C0808 - 100g - $12.70
F17B1C1015 - 325g - $26.46

The latter is good for hefting and comparing density as it is about the size of a half roll of quarters but has mass not far from that approaching that of the a common 12 oz aluminum can of liquid.

Hi Mark,

I'm still enjoying the Gallium from the previous buy.

Please write me down for:
- 1 pound of Tin.
- 1 pound of Bismuth.
- 25 grams of Indium.


Here's a couple of photos I made of Tungsten and Gallium:
Left - 40 Gallium melted and then poured into a glass containing crushed ice. The result is these very nice and shiny pieces.
Right - Big Tungsten rod - 4cm height and diameter - over 1KG (!!), small Tungsten rods 1/2" height, 1/4" diameter, each 7.7 grams, and the Gallium melted into a small dome.

I recommend everyone to buy the Tungsten in large amount, then its density gets really impressing.

Ohad

Sorry, no. I think my seller's getting pissed about all the questions. However, when I place my order, I will request 1 troy ounce ingots. If he does not carry these, I will let you guys know what sizes he does carry. I could also probably obtain 1kg tungsten ingots for under $100.

I'm very glad you are enjoying your gallium! Those crystals are beautiful. I like your tungsten rods a lot as well, they look very interesting, and I'd love to feel their density. I will write you down!

If that's true I may be interested.

What what be extra nice is to have similar size and shape ingots from Magnesium, to match the Tungsten.
Magnesium is extremely light, 1/11 density of Tungsten, and is fairly strong, and should be much cheaper than Tungsten.

It would need to be coated though with varnish to keep it from oxidizing and scratches.

I will talk to my seller about it, but he hasn't been answering questions recently, so I'm not sure if I will get a definitive answer. Sorry about that. However, I will try, and I will try to find out the prices for 1kg tungsten ingots.
