How do you translate heavy metal into Arabic?

Answer 1

It depends on what you are talking about.

If you are talking about the actual bars of metal or the elements towards the bottom of the Periodic Table, Heavy Metals = Al-ma'aden Al-thaqeela ( in Arabic ) and it written in Arabic this way : المعادن الثقيلة

If you are talking about the Rock Music genre whose lyrics and performance styles are often associated with masculinity, aggression, and machismo, Heavy Metal = musiqaa al-mitaal OR al-hifi mitaal and these are respectively written in Arabic as موسيقى الميتال AND الهيفي ميتال
