Talk:Nichrome

[Untitled]
Nichrome is not used in dental fillings. Chrome cobalt alloys are used in frameworks for removable partial dentures, but not fillings. — Preceding unsigned comment added by BoraBora98 (talk • contribs) 00:44, 8 September 2023 (UTC)

Figures in table of properties
The figures in the table of properties were pretty hard to come by, and seem to show a wide range because of the dependence on physical composition. These figures were converted from selected websites. Perhaps a reference to a proper materials reference manual would be useful at some stage. — Preceding unsigned comment added by 132.181.52.201 (talk) 07:20, 2005 July 11 (UTC)

Soldering NiCr wire
Is there a technique/process for soldering NiCr wire to another object (e.g. gold plated pad on a circuit board)? The very nature of NiCr seems to preclude solder wetting. — Preceding unsigned comment added by 208.136.201.2 (talk) 19:39, 2006 May 5 (UTC)


 * Nichrome is almost always connected by some sort of mechanically-tight connection such as crimping, riveting, etc or by welding.

 * I soldered some fine Nichrome wires to a PCB recently. It required: scraping the wire clean, pre-tinning a length of wire using acid flux, building a solder mound on the copper pad on the PCB, covering the mound with excess RMA flux, then pushing the wire into the mound with a brief soldering-iron push. Still didn't work well, and in fact the wire often de-wetted, un-tinned, spontaneously.  Soldering in an oxygen-free atmosphere would help greatly.  You can see why crimping or welding get used. jimswen (talk) 08:39, 8 August 2009 (UTC)

Nichrome heating
Is there any data about the use of nichrome heating, for instance: a nichrome element in the cables of electric kettles, geysers and spiral stove plates? — Preceding unsigned comment added by 196.209.82.171 (talk) 08:00, 2007 February 7 (UTC)

-someone asked sometime

Good table of the basic application parameter data at http://www.wiretron.com/nicrdat.html. -96.237.8.86 (talk) 23:02, 18 May 2009 (UTC)

And good tables listed here: -71.174.179.130 (talk) 13:07, 19 May 2009 (UTC)

Protective layer of oxidation
For heating, resistance wire must be stable in air when hot. Nichrome wire forms a protective layer of chromium oxide.

We need an expert to tell us about this layer of oxidation! Exactly what is it, what are its electrical and thermal conductivity properties, and how to make connections of various types -- solder, weld, crimp, etc -- through it? -71.174.179.130 (talk) 13:07, 19 May 2009 (UTC)

Expensive alloy
I was under the impression that nichrome is expensive because of the chromium, not the nickel...  Tobytb (talk) 15:59, 7 June 2009 (UTC)

Units
Should we convert properties to standard units? For example for density it should be in mg/cm3 --JayDub (talk) 17:47, 9 July 2009 (UTC)

Oh please, yes, yes yes! I came here to leave a far less polite comment on this issue. — Preceding unsigned comment added by 105.224.27.187 (talk) 08:43, 3 June 2013 (UTC)

Yes, please - 'ohms per foot', that's not useful. --217.228.166.35 (talk) 22:49, 21 February 2019 (UTC)

page or matrix of vendor technical references for alloys?
For alloys such as Nichrome, it seems the best / most-available references are vendor technical data. Different vendors cover different sets of alloys or properties, and Wikipedia necessarily has a growing number of alloy pages. So I'm noticing that it would be difficult to ever finish inserting all applicable refs in all the alloy pages that need them. Is there an indirect or collected way to do it? Such as a page with a table or list of alloy references, each one of which could be easily ref'd in each associated alloy article? --jimswen (talk) 08:52, 8 August 2009 (UTC)

curie point?
does anyone know the curie point of Nichrome-80? I'm guessing it's lower than pure Nickel, like Monel is, but would like a competent opinion 65.118.97.26 (talk) 17:19, 15 January 2020 (UTC)

Lack of photo
After 17 years, there is still no photo in this article to illustrate what nichrome looks like? 173.88.246.138 (talk) 00:41, 26 July 2021 (UTC)

Article subjectively gutted? Bring back the property tables
This makes no sense. Removing such important information was "utterly useless." Was this ever discussed, or is this just one user's opinionated culling? Bring back the data tables! 76.180.139.90 (talk) 05:23, 25 March 2022 (UTC)

 * I completely agree. For a home-based, retired, but still A RESEARCHER, losing access to physical properties of common materials is a major blow. I can't afford to run to a university library, just to find out the permeability of a material I might want to use in a high frequency circuit. Wikipedia is not JUST an encyclopedia; it is a major reference work for the rest of us! 172.103.222.67 (talk) 19:57, 1 February 2023 (UTC)
 * I would not design a dog house based on only information in Wikipedia. There's a whole World Wide Web, we don't need to replicate every page in the Wikipedia. --Wtshymanski (talk) 20:56, 8 February 2023 (UTC)
