They call materials based on tungsten as WS2 (Tungsten used to be known as
wolfram so it's atomic symbol is the letter W)

They sell powders, oil additives and greases. look at 8.pdf for
specifications. It will work with any metal or plastic.

I got into this through sharpshooting and hand reloading ammunition. I
wanted something that would not score the barrel, kept velocities high and
had minimal fouling.

 I have canning jar full of powder. ($54 a pound, enough to last several
lifetimes) What I use the powder for is on firearms. mixing a tsp of powder
with a few oz of methanol and then applying it internally on a pistol or
rifle and then rubbing the rest into the exposed metal, it takes on this
crazy luster after you hand polish with a dry cloth. Realize that you want
to use surgical gloves with this "stuff" as when it gets onto your skin it
is a semi permanent tattoo. After a firearm is polished the stuff does not
rub off.

After cleaning the barrel I pull a cotton patch through the barrel soaked
in the methanol/ tungsten disulphide and do not rub it off. The first round
through is going to swab this stuff even tighter into the surface of the
barrel ( my ammunition is coated in it as well).

I used the oil additive in my Mercedes, immediately after I purchased it I
went with the liquid additive. Now I just blend a tablespoon full into a
half a container of Mobil 1 and drop that in during an oil change.

The grease, that is some sort of magical stuff. I would almost say it is as
amazing as liquid helium II that can flow uphill (analogy there). I bought
a five pound tub and it is glittery grey/black and must be one of the
smoothest substances I have ever seen. I made a small gift of an corked
vial to a friend who does all sorts of restoration. it so reduced the
coefficient of friction between the plastic cork and the glass vial that
the darned cork will not stay in. When transferring some grease from the
tub to the vial I ended up with a very tiny amount on my fingers. Cleaning
it off was a nightmare, no soap had enough surfactants to break down the
bond between my skin and this grease. I just had to wait for my skin to
wear off over the next week or so to make it go away.

What I pay attention to is the Coefficient of Friction (CoF) and Load
Bearing capacity. Another handy benefit with the lubricants I have been
working on is that they are extremely hard and actually embed themselves
into the base metal in an almost alloyed state a few atoms thick. In other
words, once it has been on there and been between items sliding or
compressing together it permanently binds to the base metal.

Here are a few comparisons;
Tungsten Disulfide               0.044 CoF      400,000 PSI load
Hexagonal Boron Nitride      0.15 CoF       300,000 PSI load
Molybdenum Disulfide        <0.1 CoF         250,000 PSI load

With nearly every lubricant when you increase the load pressure the
Coefficient of Friction will increase. Tungsten Disulfide actually does the
opposite, the more pressure, the lower the Coefficient of Friction.

For the naontech based powders (smaller grains) you need to be careful as
the powder can practically go right between the cells of your skin and
right into your body. It behaves just like a solvent and is absorbed.
