Metal Fabrication (Titanium?)

05/06/2016 9:18 PM

I am searching for anyone who can re-create a small metal piece we use on our equipment with an indestructible material (titanium?)

This shaped piece needs to be able to flex, but cannot be bent out of it's normal shape. Am I looking at the right material? (I looked at websites with eyeglass frames that return to normal shape)

It is a small piece - approx 50mm x 20mm x thin

Any help/hints? I'd like to convince my company to start making some better parts!!

Nothing is indestructible.

Ti is light and very stiff, but brittle in thin (eyeglass frame) thickness.

Need a drawing, photo and some idea of what it does.

We used to make custom Ti pump impellers.

"Thin" means different things to people who work in different fields. We commonly use Ti alloys in ribbons from 0.002" to 0.008" in thickness. At that thickness, flat ribbons are pretty flexible, as long as we don't try to bend them around truly sharp corners.

It is much stiffer in terms of springback after bending than most steels, but we successfully bend it into shapes for producing honeycomb. The corner radius around which it is bent is a critical factor.

I suspect you are correct in your other post suggesting the OP is looking for Nitinol.

Not enough information. What does said part do in what environment is a start.

And what force does see and how much does it need to flex?

I think OP is looking for Nitinol:

Have seen the "Latest News from Engineering?" An Affordable, Elastic Steel Alloy? "Engineers in California have designed and fabricated a type of steel that they say has the ability to withstand extreme impacts without deforming permanently.

Named SAM2X5-630, the new steel has one of the highest recorded elastic limits for any steel alloy, according to the researchers. The alloy can withstand pressure and stress of up to 12.5 giga-Pascals or about 125,000 atmospheres without undergoing permanent deformations."

It sounds like you want some kind of spring metal, maybe spring steel?

Sorry for delay, busy work week.....

The piece is used as a pair, operating in equipment for lab work - it picks up a small sample tube from a holder. Working in atmosphere, no chemicals involved. Normally (with all aligned) there is minimal flex as it grabs a tube. At worst (bad alignment) it may hit the tube and bend one of the pieces.

I can check out some of the links for the material listed, but I'd hoped I could find someplace to manufacture said part......

We still need to see a sketch or photo of the shape you are talking about, in order to have any idea how to fabricate it, or what material(s) is/are appropriate.

You are looking for "Unobtainium". That alloy is known to be present at the farthest reaches of our galaxy at apocalyptic time. Not presently available on Terra Firma.

https://en.wikipedia.org/wiki/Unobtainium
or, perhaps,....... Vibranium
https://en.wikipedia.org/wiki/Vibranium

Vibranium was first deposited on Earth by a meteorite 10,000 years ago. The first documented discovery of Vibranium was during a human expedition to Antarctica. This particular isotope of Vibranium was dubbed "Anti-Metal" due to its property of dissolving other metals.[1]

A different variety of Vibranium found in Wakanda absorbs soundwaves and other vibrations, including kinetic energy. Absorbing sound waves, vibrations, and kinetic energy makes this metal stronger. It was discovered by the Wakandan king T'Chaka, father of the Black Panther T'Challa. To protect this resource, he concealed his country from the outside world. T'Chaka funded his country's education by occasionally selling off miniscule quantities of the metal. As a result, Wakanda is one of the world's most technologically advanced nations

Haven't you heard. There is a new Vibranium in town.

"Hyperloop Transportation Technologies has announced a new technology that's going to raise the hackles of Marvel's lawyers. The company, in collaboration with Slovakian materials firm c2i, has created a carbon fiber composite that'll cover the inside and outside of its capsules. The only issue is that some bright spark decided to call this wonder material Vibranium."
