Default Re: Tungsten rod 1/4"

It's also used commonly to counterfeit gold. It weighs only 0.36% less than gold does by volume. Every now and then you'll read about someone who bought some gold bullion bars find they were scammed by someone having drilled out holes in the gold bar and and replaced it with tungsten. It is nearly twice as dense as lead, has the highest melting point of any elemental metal, and has one of the highest tensile strengths as well. It is a very cool metal as far as properties go. As a reloader I've always wanted to have some bullets made out of this stuff just to see how well it would penetrate compared to the available military style penetrator rounds found on the market.

Jeff, you think you could turn me a few bullets down in this stuff? 0.224" and the same shape as an FMJ 223 / 5.56 projectile? If you could I might be interested in having about a half dozen made. If they worked well I may even have you make a hundred or so. Would be a very novel round to mess with. Not sure how they would treat my barrels though. May need to copper plate them.

Default Re: Tungsten rod 1/4"

It is used for several things, first it is used with high pressure air and electricity when cutting thick steel, and the Tesla coilers use it for rotary contacts since it can take a lot of heat.

Yep your going to have to encase the tungsten penetrator in lead or a sabot or it will tear up the barrel for sure, and I can't turn this stiff it's much too hard it has to be ground with silicon carbide to cut or shape it.

I've been experimenting with damascus steel. I wounder if I could throw this in the mix. Because of its high melting temp, I'm wondering if my forge is capable of welding it.

Default Re: Tungsten rod 1/4"

Where I work, they use a tungston alloy as a balancing weight for crankshafts.
I think it is alloyed with iron, as it is weldable, and somewhat machinable, although very tough!

Default Re: Tungsten rod 1/4"

I suspect they use Tungsten because it is hard and will not shed metal and change it's weight over time.

I think it is alloyed with iron, as it is weldable, and somewhat machinable, although very tough!

Shipping would be $4.00 to you my man, as an anode/cathode Tungsten would last a life time...

I could definitely use these as anode/cathodes for my DIY gas laser builds in the future.

How much does an inch of this stuff weigh?

You better have a hot flame! This stuff melts at 3400 C and about 6200 F, as opposed to your standard carbon steel around 1500 C and 2700 F. Almost x2.5 more temperature required. I'm thinking it would require an arc type of smelting process. I don't remember how hot oxyacetylene gets but I don't think it's that high.

Default Re: Tungsten rod 1/4"

It's right at 15 grams per inch give or take a few cents, a 18" rod weighs in at 9.5 ounces, I just weighed a 1/4" diameter steel rod the same length and it weighed 3.9 ounces.
