Titanium gets used in wrought aluminum alloys (i.e. 4 digit alloys like 6xxx, 7xxx, etc. type series including classics like 6061, 7075) mainly for grain refinement during the casting process. Ti forms intermetallic TiAl3 solid particles in the molten aluminum which Al grains nucleate off of. Usually they also add grain refiner rod containing TiB particles, which nucleate grains as well. More grains nucleating = smaller grains = more grain boundaries = stronger material.

Love a good metallurgy mic drop.

I can see it now on Blizzard's website--REFINED GRAIN PLUS FLIPCORE FOR THE HIGHEST PERFORMANCE SKIS WE'VE EVER MADE

As I understand it from hanging around a ski building shop, titanium has many compelling characteristics, but due to some chemistry stuff forms a poor bond with epoxies. Aluminum is more porous and bonds well. I like skis with metal; one of my favorites of all time was full rocker 184 Katanas. That’s all i can contribute. Happy thanksgiving!

I wasn’t inferring that that the metallurgy would be effected by marketing. But they don’t admit that it’s basically an aluminum sheet. They aren’t going to call it Molynal or Magnanal, Chrominal?
Nope, go with unobtanium.

did some mfger make an aluminium ski say back in the 80's as in the whole fucking ski top sheets and all was aluminium ?
some guys i worked with used to talk about these mythical skis that someone had bought from a whistler ski patrol
real or bogus ?Last edited by XXX-er; 11-25-2022 at 08:46 AM.

I think Goode made teh carbonz, but if I'm not mistaken, head made a mostly metal ski way, way back.

Aluflex?
Aluflex skis had/have metal topsheets. Still made today @ shapersalpins.com.https://shapersalpins.com/produit/sk...-fiberflex-gp/
Truflex was the 1st mass produced aluminum ski. With no damping, it proved to be nearly unskiable in hard snow conditions. The company that built it also invented snowmaking and abandoned ski making and licensed the design to Adopt Attenhofer. Attenhofer had the ski built in France. After solving ski ability problems(addition of wood core) the ski became known as Aluflex. Aluflex merged w/Starflex and became Dynastar.

This research study seems to corroborate what I've been saying. Titanal, by itself on skis w/ similar mass and stiffness,has 0 affect on damping

Not an engineer, but I would think having different materials would result in different vibration resonances and thus result in a damping effect. So by extension adding aluminum would cause greater damping than a similar ski without

Not according to that testing.
Of course lab testing is probably a little flawed in terms of what's happening in real time on snow but.....

I think adding titanal allows additional mass and stiffness without changing the profile too much. Damping is largely created by fiberglass and/or rubber.
I’ve used a really damp ski with no metal, Rocker2 100 but they lacked the stiffness and mass of a metal laminate ski to plow through variable snow

Boneshakers are a pretty damp ride. Pretty stiff too. They crush the variables! 0 metal!
I'm not quite as big as you, but my brother skis them too. You've got a few lbs on him, but he's 6'6" 220. We both DD'd those skis for yrs!

Metal skis - inherently demanding?
It’s subjective of course, but I didn’t think that the Boneshakers were that stiff. Heavy for sure and not noodles by any means
I will say that ski seemed under rated

We'll, I did say pretty stiff. And they do crush variable
Also, the testing in that research study was for skis with similar mass and stiffness

A good friend still uses that ski, loves it. I’d definitely ski a pair in good shape

It's my favorite ski I've ever been on.
So, I whoarded some

They were talking about some ski that this patroler brings into the bar at whistler probably late 70's back when there was no whistler, fueled by bad canadian draft beer he puts them on a chair so he can jump on the tips which somehow impresses my buddy so he buys them, and i have always wondered about that storey
i do remember a GS design of the Volants being a pretty good skiing ski except i think they all delaminated eventualyLee Lau - xxx-er is the laziest Asian canuck I know
