Shiver me timbers.

How is the alloy heat treated?

Do you have a TTT curve you can publish for the product you are laying claim to produce?

and what is its modulus of Elasticity?

[grey_whiskers]

I would like the hear from others as to what they may consider as uses for this exciting new product.

Bicycles!

...oh, and is the company publically traded yet?

Cheers!

Probably have to use a larger tube like alum or titanium (larger than steel) and thicken the tube walls so the frame doesn't produce a mushy ride. I like the stiffness of a steel frame but the lighter weight of alum and titanium is also a nice feature.

Agreed!

Dark, are you an engineer or designer of frames? Or a rider?

Cheers!

I think it would be great to use for bike frames. Currently used materials are:

• Steel Alloy (Cheap, heavy)
• Aluminum (Moderate cost, relatively light, stiffness makes for a harsh ride)
• Titanium (strong, very light, very expensive)
• Carbon fiber (very light, somewhat out of favor)

There's probably others, but these are the materials of which I am aware.

Actually aluminum is a stiffer (more jarring) ride because it does not flex as much as steel.

[Scutter]

When you can say, I would love to hear who the bike manufacturer is.

Hey "grey_whiskers./"

I am just a daily long-term rider.

I am a successful bipolar "convict" who has used the bike to escape the need for medication.

I am 58 y/o and ride 5-6 hard hours a week.

Love my bike. It has saved my life many times over.

I spent my career on Wall St as an investment banker until my "condition" overtook me. Now I ride and write.

Things are better now than before.

My brother was a hyperactive kid as was I. He is also a committed cyclist.

I recommend it to all who like or need exercise (which IMO is all of us).

Good luck with your cycling.

I have never owned an alum frame but have been told that the reason the alum frames are bigger tubes is to achieve comparable stiffness with steel.

I have always riden steel frames.

Can't argue the technology since I haven't riden alum or titanium.

You are 100% correct, and I am wrong. Apparently I was the victim of a popular myth. Details here.

[Dark Skies]

You may by wrong (I don't know that but you say you are) but wrong or right you are obviously a big man (a man of big heart). It takes a real man to so freely admit his error (if indeed it is).

You have earned my respect. Thank you for your example!!!

How wonderful to be wrong about unimportant details and be right about one's soul.

My greatest thx!

[RetiredArmy]

I'll stick with my carbon bikes.

Thanks for the kind words. I saw your post about Wall Street. Do you ride in the NYC area? I travel up there every 3 weeks or so for a project I am working on. I love the area, but not being on a bike for a week is tough.

[Dark Skies]

I live down South now (in Georgia) where I grew up. Spent many years in NYC and love and miss it much. Used to ride in Central Park on weekends and daily in the summers. Bought one of the first Specialized Stump Jumpers in 1985 on the upper East Side. I gave it to my Dad and it is still out in the shed.

Have ridden Specialized and Trek ever since.

Riding makes the body and the mind strong. Keep riding!

LOL. That's where I live -- Suwanee, GA -- a suburb north of Atlanta.

[Ernest_at_the_Beach]

Thanks.....good stuff...

Cvengr I will get thise figures in the next couple of days.

But all of the specs have been increased and the material can be extruded.

[Rockpile]

A kind of "out there" potential use would be for airship frames and fittings----if any ever get much past the drawing board.

[grey_whiskers]

Have ridden Specialized and Trek ever since.

Nice brands :-)

I have a Specialized for commuting and a Cannondale road bike; my wife has a Trek commuter bike and a K2 mountain bike.

Cheers!

We live off of 6061 when building space hardware. A lighter, stronger material would be great as long as it's not too much more expensive.

You wouldn't happen to have tried polishing it to optical quality, would you? Matching materials means the whole system is athermal.
