Thank you! Unexpectedly, it is Latin root + "-ide". I could comfortably read stuff like "AlCu" now, although wikipedia does not provide complete nomenclatures for every element.

Thank you for replying. I know actually they don't form an anion. But in alloys I constantly meet something like "AlCu". Al "anion" is called "Aluminide". I didn't find anything for Cu. I just want to know how to read things like "AlCu".

Hi everyone! I am an English learner and I would like to know how do people name intermetallic compounds. For example, Mg2Si is "magnesium silicide". Then what is the name of AlCu? How to add "-ide" to copper?
