Are these weights pure tungsten, a tungsten alloy, or coated tungsten (i.e,. zinc-coated)? I need a (reasonably) pure sample for an experiment.

As a chemist I would not count on these as being reasonably pure. I use them as an alternative to lead as weights of high density. You may be able to approach an industrial manufacturer for some samples.

I calculated 0.576 oz per unit (.875" x .46875" cylinder) if the material is pure Tungsten. Assuming there are 6 units, they should weigh 3.456 oz.

No idea. I can't help you. You'll have to ask the manufacturer.And, we took 3rd overall this year! Whoo! Pinewood derby is fun!

The ingredient only stated "Produced from naturally occurring zinc ore, super purity (free from other metals) Particle size &lt;1000 nm " Hope that helps.

Wire is coated. Cannot see the wires. The probe is metal. Possibly stainless steel.

They are cast iron weights. About 3 pounds each. Works pretty well. Had the vest since christmas and ive had it on ever since. Its really improved my overall results :)))

Yeah, right, "stainless steel". Solid stainless steel would cost more, even brand-name razors are not usually stainless steel, unless very expensive. Typically it's chrome-plated brass, nowadays. Could be nickel-plated, but some people have allergies to nickel, so it's not common anymore. Never solid nickel or chrome, not for cheap :)

I can safely say they are galvanized "metal". Not sure about steel verses tin or aluminum, but they are definitely metal and I would suggest that they are unlikely to burn under normal circumstances.

You can buy the plates 1,2,3, or 4. It is up to your needs if you need a pair. I would go with rubber coated. I have had my wieghts for 4 years coat wears well, and is not as expensive as American Steel. I also have rubber coated dumbbells and they are the best I ever had.P.S. Body-Solid cuts out the middle man, so your are buying for less.

The chocks are zinc plated steel. I'm unsure about the grade of the steel used. I've used them now several times and they are holding up just fine.

I don't use tungsten but use one of my old Bowen monolights that works very well. It has a modeling light that helps you see what you'll get but doesn't produce the heat tungsten provides.

I can't answer that question because I'm not aware of any metal being present in that product. If you know of any name or type of metal in them I would gladly appreciate you making me aware of them. Thanks

HI. I made a ball of aluminium of 2.64 grain for you and dropped it on the scale over 10 times, also 10 times in between was another weight of 45.08 grainboth number were constant on every time. in resume, I can't tell you my 2.64 grain ball was exact, but it sure was constant.good luckPS, you should start a question with Hi at least... just saying :-)

They are printed weights. I have had this scale for a year, now, and have had no problems with accuracy.

I can only guess that the other 1% is composed of "impurities" such as manganese. It would be virtually impossible to market something as 100% pure iron. Wish I were of more scientific help.

Yes, they are "magnesium". I use quotation marks because they are not true magnesium rods. They are higher in magnesium content than a ferro rod, which is higher in iron content. These tend to throw blobs of molten magnesium as opposed to a shower of sparks. I wouldn't recommend these if you're main use is going to be lighting an alcohol stove, but they are fine for igniting tinder. One thing...don't expect Exotac or Light My Fire performance from these fire starters. Thy are priced low for a reason. For the price, they are decent. For everyday camping/hiking, they will get the job done, but if my life depended on a fire steel, I would much rather have an Exotac. Hope this helped. Yes, they are "magnesium".

I assumed they were stainless steel, but I'm no expert in metals. It could be aluminum. Sorry I couldn't be of more help!

A thin layer of metal, I don't know different types of metal not sure what you are asking. I lost mine it came off my wrist and I didn't know it.

I use lead.... but they make more expensive alloy pellets.. the lead is more accurate due to the weight
