I wonder if
@calinbotez got Ti or maybe something else?
It's like pink or anythink, you don't really know what you got.
Considering the absurd prices Ti wire fetches, it's
not surprising if people fake it.
I have Ti grade 1 wire from Galllium Source
and Spider Silk wire from envyCIG.com a.k.a.
"wire by envy". Both are about 28 gauge and are
thus supposed to be 0.40 mm. I use 28 gauge
all around. It's a good general thickness wire,
and using the same gauge makes things easier.
The gallium Source wire is 0.38 mm and uneven. It's
coated with machining oils, no big deal but at these
prices they should clean it. Resistance is around
0.044 ohms per linear cm. It's a bit rough-looking.
The Spider Silk is more even, 0.40 mm thick and
0.040 ohms/cm, shiny and much cleaner. I object
to the misinformation they spread, like the idea
that cleaning wire with acids could leave residue
of hydrofluoric acid. That's nonsense because HF
is so reactive it reacts with everything and couldn't
possibly remain on the wire, the packaging, anything.
Their BS aside, their wire is of good quality.
Neither Ti wire seemed especially unmanageable
or springy. I had far more trouble with plain Nickel,
and was happier with "tempered" nickel wire. That is,
until (after a week or more) I started feeling like I
was breathing something less than ideal, with pains
in my chest, and so I switched to Titanium, whereupon
all this discomfort disappeared.
The resistance of 28 gauge Tempered Nickel measured
0.0124 ohms per linear centimeter. If you have a
decent ohm meter you can check the resistance
of what you have before winding a coil.
A 10 centimeter length of 28 gauge (0.40 mm) thick
Ni200 Nickel wire should measure around 0.12 ohms.
A 10 cm length of 28 gauge (0.40mm) grade 1
Titanium wire should measure around 0.40 ohms.
