content: Hi,Ive searched the entire web and cant find 0.3mm enamelled copper wire.Only 0.315mm enam copper wire i can find. (ie, 30SWG).Please confirm there is no such thing as 0.3mm enamelled copper wire?Our customer insists on it.

content: Demanding "0.3 mm" is logically absurd.The specification must include a tolerance on the numerical value, and if the value be expressed with only one significant figure, that tolerance must be broad.I didn't know anyone made SWG wire anymore.In AWG, #28 is 0.32 mm and #29 is 0.287 mm.

content: Hi,You don't say how much you need - but it certainly exists:https://brocott.co.uk/0-315mm-enamelled-copper-winding-wire-4kg/https://brocott.co.uk/0-315mm-enamelled-copper-winding-wire-10kg/Smaller amount?https://brocott.co.uk/0-315mm-enamelled-copper-winding-wire-250g/https://brocott.co.uk/0-315mm-enamelled-copper-winding-wire-dual-coat-2kg-spool/This last is dual-coated - you don't say the use, so that could be important?So, yes, available, in various quantities and coatings etc. (I know of a couple of others - but these are who I've used so know they work).Hope that helpsETA:p.s.Seeing one of your other threads, Brocott workj to all the standard specs and have all the necessary paper work if your use requires it. (Wire spec'd to 200 deg.C, Standards IEC60317-13 & DIN 46416-7 etc. been used for MilSpec/Gov.t apps successfully)

content: Quote from: Paul Ed on December 11, 2022, 07:27:52 pmYou misread: he is looking for 0.300mm and has only been able to find 0.315mm, which is not what they want.

content: My emphasis, Farrigdon said "ie, 30SWG" here:Quote from: Faringdon on December 11, 2022, 06:18:53 pmSo as I've used 30 SWG, but also checked the size on three sites, here:https://www.rapidtables.com/calc/wire/swg-to-mm.htmlandhttps://supermetalind.com/swg-to-mm/andhttps://www.calculatorology.com/swg-to-mm-calculator/When asked for 30 SWG to mm, gave yes you guessed right:0.315mmWhich is why I gave the links you quoted sir.Quote from: tooki on December 17, 2022, 02:51:56 pmAs 0.315mm seems an acceptable size for 30 SWG?(Even in my Grammer school time the UK taught us the SI system so I've been using it ever since, usually converting non-SI to SI when needed, as SI units are coherent and self consistent)

The 30SWG was what he FOUND, which is not what he WANTED.Quote from: Faringdon on December 11, 2022, 06:18:53 pmHere, I’ve translated that to English:“I searched a small part of the web to find 0.3mm enameled wire and was unsuccessful.I was able to find 0.315mm (aka SWG30) wire, but that’s not what I need.Please give me proof that 0.3mm wire doesn’t exist, so that I don’t have to keep looking.”
