Add zinc alloys?[edit]

ZAMAK is listed under the alloys of aluminum, but the ZAMAK alloys are mostly zinc. Should a category of zinc alloys be added to this page? Chuckhoffmann 20:41, 1 August 2005 (UTC)[reply]

all lists are very useful so zinc alloys should be added together with their recommended usage.

I have been searching for a list of aluminium equivalents. One country uses a set of numbers and another country a completely different set of references. I am looking for an aluminium that can be pressure die cast and then anodised. Needless to say the aluminium should not contain silicon

I think that Tin should come before Titanium, alphabetically... — Preceding unsigned comment added by 66.65.107.234 (talk) 23:23, 8 March 2020 (UTC)[reply]

Removal of hydrides?[edit]

Someone has gone through the list and added several metal hydrides to the list. Most of the first row transition metal hydrides are unstable, don't fit the definition of an alloy and should be removed. However, there are several more esoteric complexes listed, such as UH3 that may in fact have stable hydrogens impregnated into the crystal lattice.

Color coded diagram[edit]

It would be neat to include a diagram of alloy composition, with constituent elements coded by color. Probably the most useful presentation would make each alloy a horizontal bar, divided into colored blocks whose width indicates percentage. A sensible ordering could be devised. This would allow rapid visual appraisal of alloy composition. If I have time, I will have a go at constructing such a diagram (automatically) from a textual table.

tx10 alloy?[edit]

Where can i find information for a mill alloy (tx10) hardness 62RW?

Magnesium-Lithium[edit]

There are also Magneisum Lithium alloys. I don't have a good reference handy. —Preceding unsigned comment added by DonPMitchell (talk • contribs) 04:24, 12 August 2008 (UTC)[reply]

Silvanium - removed[edit]

I removed reference to "Silvanium (Silver, Steel)", as I beleive this to be an obsolete name for Tellurium, rather than an alloy of silver and steel. See [1] Tommfuller (talk) 11:12, 5 February 2009 (UTC)[reply]

Maybe someplace gold quality is assigned the word for diamond weight ( carat) but in the USA gold is Karat with a K.

Iron Copper Alloy[edit]

Are there any Iron/Copper Alloys? If so, are they strong? I read something but I think it was based on fiction. -- Azemocram (talk) 01:08, 8 October 2010 (UTC)[reply]

Alloys of Iron are limited to being within melting-boiling point range (Iron 1450-2850 C) and electronically compatible with valence band. Magnesium, Lithium, and Zinc boil before Iron's melting point. Lead and Tin have a common liquidus range as Iron but different chemistry. (One can create a Lead-Aluminum solid by cooling rapidly after homogenizing but not a real alloy.) Iron-loving or ferrophilic metals are all carbide formers: Titanium, Vanadium, Chromium, Manganese, Cobalt, Nickel, Molybdenum, Tungsten, Thorium, et al. Calcium, Copper, Gallium, are not intermetallic Carbide formers. Note that some alloys can be formed by electroplating two metals together that may not be compatible as melts.

Gold Palladium Alloy[edit]

This is a very common alloy in high end watch and jewelry and should be added to the main page... -- Rdavid01 (talk) 12:50, 27 July 2011 GMT+1

Thanks for your suggestion. AuPd's other name is white gold, as included in the list... >MinorProphet (talk) 23:06, 27 July 2011 (UTC)[reply]

Problem[edit]

Got a mistake here:

Wrought iron is not an alloy, it is a composite. Also, its secondary element is not carbon, but silica.

Not interested enough to fix it. Have fun. — Preceding unsigned comment added by 24.10.27.75 (talk) 05:19, 3 January 2012 (UTC)[reply]

Alloys of Steel -> Alloys of Silver?[edit]

I'm pretty ignorant here so I'm not going to change it, but shouldn't this section refer to silver, not steel? — Preceding unsigned comment added by 66.255.205.45 (talk) 01:10, 26 February 2012 (UTC)[reply]

Fixed, thankyou. This page gets a small number of "unhelpful" changes, apparently perpetrated by bored schoolboys with marginally more intelligence than the average piece of seaweed. Most vandalism of this type is done by ~~anonymous morons~~ people with an IP adddress rather than an account name. I imagine they will grow up some day, but I have my doubts.

Feel free to combat the forces of boredom and stupidity by boldly reverting this sort of edit. In the "View history" tab you can see the differences between versions: click "undo" at the end of the offending line (if this is the most recent change) and leave a brief edit summary, followed by "save page". Even better, why not create your own account and join the wacky world of wiki? Even if you are not logged in, please sign your comments by typing four tildes ~~~~ at the end of your post.

Ferromagnesium?[edit]

Magnesium boils 400 degrees before Iron melts. Magnesium in Iron is limited to ~100 PPM. Magnesium is added to high carbon cast Iron to modify precipitated Graphite (to increas strength) at a level ~50PPM. Not really an alloy in the definition of the word.

Alloys? from the Electronics Chemist[edit]

I've done a lot of solder and electronics industry materials work. Some notes. 1.) Solder reacts with solder surface to form a melt solution of Cu3Sn (gee! that's the limiting composition of Bronze!) and Cu6Sn5 dissolved in Tin and precipitate on cooling. Silver solder is a solid "solution" of Ag3Sn in Sn. 2.) "Solder" contains from 50% to 97% Tin; should not be listed as Lead alloy. Ancient non-Tin Lead (Antimony) solders were used in plumbing at one time. Hard to consider Lead-Tin et al solid compounds as alloys since Lead is excluded from the other metals on solidification. 2a.) With an eye towards RoHS regulations 3.) Nickel-Tin intermetallics in Tin, after reflow of Tin (Solder) plated Nickel circuit board traces. 4.) Also note a Nickel-Tin alloy used on doorknobs, plumbing fixtures, etc. that was electroplated. Alloys not otherwise createable from melts can be coplated. Common material on fasteners (screws, nail, etc) for corrosion resistance (to replace Cadmium) is Zinc-Nickel and Zinc-Cobalt which can only be plated as alloy.

Iron Alloys - Steel (Damascus Steel, Wootz Steel)[edit]

Are Damascus Steel and Wootz Steel not the results of forging techniques on existing steel crystalline forms (mostly martensite and pearlite) and not actually alloys in their own right (but composites)? Tamahagane (Japanese sword steel) could be added in the same category.

Copper-Zinc Alloys (Addition)[edit]

What about Tonval Brass? - Leaded Muntz metal: α+ß brass 1.5%-2.6% of lead. more than 38% Zinc. UNS: C37700 Specification: CW617N

What about Admirality brass?

what about ß+Γ brass, that used for brazing and electrical components? .. . . — Preceding unsigned comment added by 149.78.230.233 (talk) 18:13, 8 July 2015 (UTC)[reply]

The first two are covered briefly in a longer list at Brass#Brass types, which I added as a 'see also' link in the Copper section. I also added Gamma brass to the table of brass types there. However, this is a list of already-existing articles or sections. You (or someone) would need to add some info about ß+Γ brass (probably) to the Brass article for it to be referenced here. Thanks for your interest. So, mostly

Lengthy essay in the middle of this list[edit]

User:Diannaa added a large chunk of text at Carbon Steel here. I don't disagree with any of the content, in fact it's remarkably cogent, well-referenced and informative. Neverthless, it's not a list and doesn't belong in the main text. Maybe someone could make it into a footnote, like Gold but with no {{citation needed}} needed, and revert the original copy. >>MinorProphet (talk) 17:19, 21 May 2019 (UTC)[reply]

The content was actually added by an IP with this edit. It was copied from Steel. My edit merely added the supporting citations, which the IP had neglected to copy over. — Diannaa 🍁 (talk) 18:57, 21 May 2019 (UTC)[reply]

Hi, @Diannaa: I only today realised that the 'Iron' section had been previously blanked, and that User 144.35.45.54]'s edit was to present at least a summary of carbon steels, since the section was missing. I've restored the original section from an older edit and hidden the IP's interim text. MinorProphet (talk) 20:11, 15 August 2019 (UTC)[reply]

Proposed revert to article name change[edit]

This article used to be called List of named alloys, because it specifically omitted numbered alloys such as are found in mind-bending detail at Aluminium alloys. I couldn't find the actual edit which made the change. Although I'm not entirely against the name change, in order to preserve this distinction - and to prevent a load of numbered entries - I propose to revert the current title (List of alloys) to the previous one. Some people might prefer the current name. Thoughts, if any? MinorProphet (talk) 01:55, 19 October 2019 (UTC)[reply]

Oops, I renamed the talk page to the main article, sorry etc. MinorProphet (talk) 02:15, 31 December 2019 (UTC)[reply]

Oralloy ??[edit]

During the Manhattan Project in WW2 the enriched bomb-grade uranium produced at the calutrons at Oak Ridge Natl. Lab. was given the wartime codename oralloy, probably to confuse intelligence types. The use of that name continued into the Cold War. Not really an alloy in a strictly technical sense, so should it go in the article ??? I think maybe, because somebody out there in googleland might hear about it and come here looking to see what it's about...we don't want to disappoint!! Wikkileaker (talk) 13:02, 24 July 2020 (UTC)[reply]

@Wikkileaker: I agree we should help readers who hear words find our relavant articles. If it's not an alloy, it doesn't belong in this page. But if it's about the Manhattan Project, that page might be a better place. Need a ref to support this term. DMacks (talk) 14:15, 24 July 2020 (UTC)[reply]

Wassup?[edit]

This article used to be subject to ongoing random vandalism, apparently perpetrated by bored 12 year-old schoolboys barely enlivened by a sense of self-esteem that placed them only slightly higher than yer average jellyfish.

But what has happened? No reverts needed since long. Have they all grown up, as I predicted? Or has a new generation of Know-nothings grown up, but who have watched Poker Face and Stranger Things, and realised that resistance is useless? MinorProphet (talk) 02:08, 9 June 2023 (UTC)[reply]
