Titanium or tungsten casters?


#1

Hi Everyone,

I was wondering if any one could point me to someone who could cast
titanium or tungston rings for me.

Happy New Year!

Tungsten isn’t cast, it’s sintered. The melting point of tungsten is
too high for casting, 6192F.

The melting point of titanium is also very high, 3034F., but more
importantly titanium can be compromised by atmospheric gases at high
temperatures. Casting titanium is a highly specialized industrial
process.

Tungsten carbide is not cast and titanium is not cast in small
scale/small volume. Virtually every Tungsten carbide and titanium
ring you see is machined from rod stock. It is possible to do small
scale machining of titanium or even form it with jewelers tools like
your saw, burs, files etc. I do not know of anyone who is offering
titanium ring fabrication as a service. Tungsten carbide is strictly
and industrial product. It is ground to shape on a CNC diamond
grinding machine, though a lapidary could grind and polish it as well
I don’t know of anyone doing so.

Thanks for your responses!

I usually work in precious metals but this customer reallllly wants
tungsten or titanium and I have already made him a stainless steel
ring for the engagement ring.

Back to the drawing board,

both should be possible - I’ve seen both materials used in rings.

but the approach would have to be: start from stock material and
remove material until you get the desired shape.

for WC, I’d look on the internet for existing products.

for Ti, I’d look for tube stock…
