Thread: Tungsten pins?

Pure Tungsten is probably also fairly expensive.
I agree it can't be Tungsten carbide. You'd be tapping for eternity before it peens

i have in my collection a tungsten 30 mm cannon projectile. i can slam it into rock with every thing i have and still scrach glass with the point .peen it? no way

Unless you're using pure Tungsten, it's going to be granular. The molecular structure is crystal-like. It may be strong material, but it is very brittle. It is much like Titanium. They are both strong materials, but put them under a lathe or a milling machine and they get very gritty and want to shatter.

Pure tungsten has few applications and is not generally available. It's usually alloyed. If it's carbide you can't peen it because it would break like a piece of cheap plastic-I know.

If I read the initial post correctly he is not using tungsten steel rod.

Tungsten - Wikipedia, the free encyclopedia
"Tungsten with minor amounts of impurities is often brittle[4] and hard, making it difficult
to work. However, very pure tungsten, though still hard, is more ductile, and can be cut
with a hard-steel hacksaw.[5]"

Ductile is interesting, I find it amazing that tungsten can be drawn
into the very thin filaments used in light bulbs.

In looking I noticed that some folk are making wedding
bands of pure metal and also the carbide. Interesting stuff...
