Cu tube - how thin can we go?
Cu tube - how thin can we go?
(OP)
Question arose the other day from sales engineer folk...
In the production of Cu tubing [pick an alloy], what would be the thinnest (i.e.: smallest) OD that is possible?
Is a 0.1 or even a 0.02" outer diameter tube [wall thickness, ID, etc. is not important] possible?
Of course, they are wanting the material to be somewhat ductile, walls not collapse, etc etc... want the cake, icing, and eat it all... :)
In a search of ASTM, I can find no standards referencing anything approaching this size - smallest that I am aware of is ~0.25".
Thanks!

RE: Cu tube - how thin can we go?
I don't have my references now but I know they make copper tubing smaller than stainless steel 36 gauge .004"-005" O.D.; .002"-003" I.D.; or .001" wall.
We used this tubing in the electrochemical lab quite often. We also had some silver tubing smaller than this.
With the new nanotechnology the molecule is the limit.
