aluminium vs aluminium-magnesium [solved]

I am trying to catalogue my extensive aluminium coin collection.  It is getting very annoying switching between “aluminium” and “aluminium-magnesium” in the drop-down composition field to find the coin I'm looking for.

Is there really any significant difference between the these two compositions?  A lot of so called “aluminium-magnesium” coins are listed under “aluminium” anyway.  Perhaps they should be combined into a single composition like “silver” is where any coin with at least 50% silver content is classified under “silver”.

Anyway back to my original problem, is there any way to select both “aluminium” and “aluminium-magnesium” at the same time.  Typing “aluminium” in the general search bar doesn't return all coins.

Thanks.

The subject is not clear, maybe it needs to be changed. For example: Multi-selection composition filter.

There is a huge difference - those 100% aluminium coins are soft as better. The al-mag ones are a lot, lot more durable, and also LOOK quite different.

The “fix” in the post davidhs linked was to amend the search to include both composition.  However, as that post was not an idea to improve Numista, it's not being tracked and has probably been forgotten about.  I suggest you modify your post to that suggestion.

I am calling for consistency.  So many coins listed under “Aluminium” actually contain magnesium!!!

5 Francs - French Somaliland (1896-1967) – Numista

1 Franc - Comoro Islands – Numista

1 Fen - People's Republic of China – Numista

5 Poisha - Bangladesh – Numista

1 Likuta - Republic of the Congo (Léopoldville) (1960-1971) – Numista

3 Mils - Malta – Numista

1 Mil - Cyprus – Numista

and so on … and so on …

It's quite ridiculous actually.  Just move all “Aluminium-Magnesium” coins to “Aluminium”

100% agree. There are 81 Aluminum-Magnesium objects in the catalog. Move them into the Aluminum composition 9,986 objects (keep the detailed compositions in Additional details where they exist). I'm not sure why this Suggestion has taken so long to resolve (one way or the other). 

Almost all of the so-called aluminum coins are made of aluminum with magnesium. Pure aluminum is not suitable for making coins, and may have only been used for some tests in the 19th century. My opinion is to change the few aluminum-magnesium coins to aluminum, and to remove aluminum-magnesium from the list of materials.

Hello,

I merged “aluminium” and “aluminium-magnesium”. There is no option “aluminium-magnesium” anymore.

Thank you, thank you, thank you !!!
