… and others made from steel, perhaps wasting money (2,2)
I believe the answer is:
et al
'and others' is the definition.
(short for 'et alia', 'and others' in Latin)
'steel perhaps wasting money' is the wordplay.
'steel perhaps' becomes 'metal' (steel is a metal).
'wasting' indicates named letters should be taken away.
'money' becomes 'm' (abbreviation in economics).
'metal' with 'm' taken out is 'ET AL'.
'made from' acts as a link.
(Other definitions for et al that I've seen before include "And the rest (Lat. abbr.)" , "'And others, to the old Romans (2,2)'" , "Latin abbreviation meaning 'and others'" , "and everyone else)" , "And the rest, to the old Romans" .)
