Hi All,
I was wondering if one of you had already tried and used a filament made of "SisAlloy"

Following the pictures, it does look like the filament is not sagging much over time!

I've been buying and using replacement tungsten filament coils from SIS for a very long time and up until lately have been happy with the results.
Recently however, the latest batch of filament coils that I ordered have tripled in price, and they don't work nearly as well as the old ones.
I left a long detailed message with technical support but nobody has bothered to reply.
SIS recently sold out to a technology clearing house, Adaptas Solutions (think Fisons back in the '90's). As far as I know it's a change of ownership only and not a full scale take over.
My advice is to buy one and give it a try.
If it performs anywhere near as good as they say it does, great.

SISalloy may be OK by itself but see thread to see how having yttria coating affects things....
