I read a lot from this guys and can't find a real explanation for the alleged benefit of the proces.
I also have a problem with "scientists" whom keep using the imperial units system instead of the world wide SI-system used by real scientists.
Besides that, if one hears an improvement in whatever they "ice" they should continue doing it.
The proof puts pudin inside your ears.
From what I understand the cryo process tends to re-organize the lattice structure of the material by forcing the matrix of the material into a 'tighter' grouping. This in turn tends to strengthen and improve the structural integrity of the whole.
They cryo entire engine blocks for race cars, and musical instruments (saxes, horns, electric guitars, etc.) and their basic character changes.
But the greatest industrial use is machine tools and bits and cutting edges of all types.
If you do get a chance to cryo anything and you use a straight razor (with 1-x) number of blades, get the blades cryo'd and see how long the edge stays sharp…
With wire it seems to to be able to 'improve' the grain structure of the wire itself which lowers the impedance of the wire in general.
In fact there are companies that actively use a cryo treatment to make the wires (Jena Wire) and others that cryo their cables as part of their cable making process (Shunyata).
But the thing is it seems no one has spent the money to do a full on series of tests to actually know what and why the process provides the changes it does.
They know what the results are and what the benefits are and that seems good enough.
And one of the benefits is increased structural integrity along with greatly increased wear life.
And since the process does not thermally shock what is being cryo'd, even some 'delicate' objects can be processed.
I'm kinda surprised it hasn't caught on more with some manufacturers etc, what with the list of benefits and all.
