TOPIC: Storage of copper wire

Re: Storage of copper wire 2 years 7 months ago #1652

Dear spectre07

The process described by you is the method that we are using to produce hermetic copper wire.

I also could not understand fully your explanation on paragraph 3,4 and 5. Would you please explain.
I am also a little confused by your suggestion.

Paragraphs 3 & 4 should have been a single paragraph.

The wire that passes through an inline drawing machine before pre-annealing and then enameling will also, with a little process control, fall within the specifications for that size wire. There is however a difference in the conductor: The wire that is drawn to size, if examined metallurgically will display a random alignment of grain structure and the nomenclature for that grain structure will include 3 different sizes.

Explanation: Again I am not a metallurgist but I do know this (note from memory, don't have the actual papers in front of me): With inline drawing you usually supply annealed or a partially annealed wire to the inline drawing machine. Typically with inline drawing you want to reduce the feeding wire a minimum of about 30% and less than 80%. Generally this means for most enameling ovens with inline drawing that 3 and at most 4 feeder sizes will be able to be drawn into the entire range of enameled wire the system is capable of producing, providing one of the major benefits of inline drawing and enameling: greatly reduced number of sizes of inventory for the enameling machine.

Properly processed copper wire using the inline drawing process results in a conductor that is more homogeneous in that all of the grains are of the same structure metallurgically plus because of this, the conductor has a higher tensile strength, better elongation, and better better springback test results than the same size enameled wire that was not processed using inline equipment.

When the company I worked for made hermetic wire we kept samples for a number of years in the event that there was a failure we could refer back to the test sample. Non-hermetic wire you will know fairly soon if it fails. hermetic wire may pass all of the tests but 6 months later fail in the compressor. Keeping samples for a period of time provided us with something to review when we did have a failure.

The point I was making was that if you were holding samples of hermetic wire you would have records of when it was first tested plus you would now have the held sample. If you retested the sample you could compare it to the earlier data and confirm that it still passed elongation or that the current value was different than it was when originally tested.

Moderators Note

The discussion on grain size and orientation has been carried forward in the Forums thread

Thank you.
