Amazing the variations of these tools.   When I grew up there were wrenches like these hanging in the shed,  dad would not use them, every time he had another jaw would break off.  Were all of them of cast iron?

Sort of.  Often 'malleable' iron, which is cast.

They're both cast, but the properties are very different. For example, cast iron has "memory" whereas malleable iron, not so much. Cast is also weaker at a given thickness. Many other differences, but, imho, those are the two biggies. Ductile iron is the best of both, again imho.

Nice litchfield. Sure looks pretty neat.
And I'm proud to be an American,
where at least I know I'm free.
And I won't forget the men who died,
who gave that right to me.

Are some wrenches made of ductile iron?

Yes, as far as I know, but only modern and mostly import. Some socket type head wrenches come to mind. Reminds ne, I need to throw some of those in the head wrench pile I have been collecting for a member here.

Our suppliers even supply ductile threaded fittings. They look similar to malleable. My trade, fire protection, uses mostly cast in 1"-10" threaded and flanged. Ductile in 1" to 2" threaded is common more and more, but mostly foreign. Malleable, like pipe-fitters use for gas lines, isn't used much for threaded. Grooved end systems (think Victaulic) are often ductile.  And domestic. Other divisions of fire protection use malleable - special hazards (clean agent gasses, refineries with galvanized.) Steel conduit fittings for A&D. Unions are malleable along with some bushings, a few other fitting types, too.

Cast cannot be used for gas piping because it is porous.
