On my rather old tube of 'regular' Araldite it says it is ok for metal.

It's no worse than on anything else.

Araldite is nearly always a poor choice (Araldite Rapid even more so),
except for its easy availability and the convenient tubes. Most uk.d-i-
y readers would do well to spring the ten-fifteen quid for a West
Systems small pack and some suitable filler (cellulose fluff isn't a
bad start, or else microballoons) (all from Axminster). A real low-
viscosity high-quality epoxy is streets ahead of ready-filled tube
epoxies. You can fill it to suit, as necessary.

JB Weld is a steel-powder filled tube epoxy. Much the same applies as
for Araldite vs. West System.

Compared to Araldite though, JB Weld is rather more useful for "heavy"
uses. The numerical strength might not look much better on paper, but
things like creep under load are improved by the filler.
