Multi-element GB (official)






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.
 
Oh crap! This forum is definitely not good for the wallet. ;D How long will you be having this GB, I will be ordering something from this..

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.

Any news on the size of the tungsten ingots?

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.

You dont know the ratio for this room-temperature-liquid alloy, dont you?

But shipping to Germany?

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.

Shipping to Germany is $10 for first-class mail and $13 for priority mail. (It varies quite a bit country to country, in case some of you were wondering why the different price quotes for shipping. I just use the online USPS calculator.)
