Talk:Magnalium

I removed a redirect to magnesium and added information on the alloy, but I forgot to log in. The edits should be recorded under IP address 24.16.154.50. Please do not revert this edit. --Pyrochem 19:08, 25 February 2007 (UTC)[reply]

Merge with magnesium aluminide

I think that this article should be merged with magnesium aluminide.

The two articles both cover very similar topics, however, they provide different information. The magnesium aluminide article focuses on the chemical and material properties of the intermetallic compounds between these two metals, while magnalium covers a broader range of alloys.

I am currently leaning towards adding magnesium aluminide as a section in magnalium.

Anyone with input on the topic, especially how the articles should be merged (if at all), should post to the talk pages for either of these two articles. I will probably make the merge in a week or two, depending on comments.

Chris-I am sorry but this is futile. People have no doubt spent hours writing these articles. Only to find them merged by some phsyco like you! All work ruined for a idiot like you!

Problem to find a reference

I had some problems to find a reference for the use in planes, there is fore sure a magnesium containing aluminium alloy, but it is not called magnalium anymore the book from the 1950s uses that word. The only stuff called magnalium is for pyrotechnics. So I think we get rid of the aerospace applications and make a pyrotechnics article out of it.--Stone (talk) 20:03, 1 June 2010 (UTC)[reply]

MAGNALIUM REACTIVITY

Not wishing to fan the pedantic flames of Magnalium, I will ignore the above. Magnalium is an amalgam of aluminium & magnesium metals. I have not come across any standardisation sheets i.e contains not less than..., .or...is first fused together..before...? etc. Generally speaking, what is found outside metallurgical research labs, appears to be roughly a 50/50 mix of Al & Mg, sold at various mesh sizes ,for pyrotechnics. What I do wish to discuss is its extreme reactivity, relative to magnesium alone. I little experience with Al (+ KMnO4, as a flash powder), however,magnesium is well-known for its extreme reactivity with this oxidiser. I always considered this reaction to be a 'little scary'. Though it has been 35 years since I made a batch of about 25gms, and created a hard thump (in an unenclosed environment, of course), magnalium /KMnO4:- 250mg, which I was to photographing decomposed in 1-2/1000th sec, with an large 'report' Such violence, with such a tiny sample, unenclosed, quite startled me. Mg is not recommended with KMnO4, for several reasons. Magnalium is suicidal. As I do not wish/need to repeat the experiment, I wondered if anyone with proir knowledge of AL/KMnO4 could enlighten me as to whther this was due to the higher energy of aluminium, or it potentiating the magnesium in magnalium? magnesium23:32, 17 June 2010 (UTC)~Prof Mad23:32, 17 June 2010 (UTC)~ —Preceding unsigned comment added by Profmad (talk • contribs) 03:08, 18 June 2010 (UTC)~PROFMAD[reply]

I think you are are in the wrong place. This article is about an alloy used for structural purposes. Wizard191 (talk) 12:52, 18 June 2010 (UTC)[reply]

I can only source "Magnalium" as an alloy of magnesium and aluminium in reference to pyro use, where it's a common term. Although magnesium-aluminium structural alloys are common, I haven't as yet found a WP:RS that uses that name (it's probably there, but it's harder to find than I expected).

Incidentally, it's not an amalgam unless it involves mercury. Aluminium reactions with mercury are quite fun though. 8-) Andy Dingley (talk) 13:26, 18 June 2010 (UTC)[reply]

Isn't Stone's ref a RS that supports its use as a structural alloy? Wizard191 (talk) 14:57, 18 June 2010 (UTC)[reply]

That would be just the thing (but not a book I have on my shelves). Please add it, then we can all move on. Andy Dingley (talk) 15:32, 18 June 2010 (UTC)[reply]

Done. Wizard191 (talk) 22:25, 18 June 2010 (UTC)[reply]
