Is 'scrap iron' the same as 'scrap metal'?

No. 'Scrap iron' refers specifically to waste iron and steel (ferrous metals). 'Scrap metal' is a broader term that includes both ferrous (iron/steel) and non-ferrous metals (like copper, aluminium).

Can 'scrap iron' be used as a verb?

No. 'Scrap iron' is a noun phrase. However, the word 'scrap' alone can be a verb meaning 'to discard' or 'to get rid of'.

Is it always an uncountable noun?

Yes, when referring to the material itself (e.g., 'a ton of scrap iron'). It is not used in the plural ('scrap irons') to mean multiple pieces. You would say 'pieces of scrap iron'.

What's the difference between 'scrap iron' and 'iron scrap'?

'Scrap iron' is the standard, fixed compound noun. 'Iron scrap' is less common and might be used in more technical or classifying contexts (e.g., 'categories of iron scrap'), but 'scrap iron' is the default term for the material.
