I have a friend and colleague who a long time ago told me that he
believed forged and struck objects to be more structurally sound than
If, he said, you put two identical objects-- say a forged and
fabricated wedding band and it's cast duplicate -- in a solution of
dye over night, the cast object would emerge with some tint to it.
The forged ring would not. His point was that even the best casting
produces a porous product while forging, striking, etc. works the
metal into a denser material with a more refined grain structure.
Most ingotted metals begin as cast objects: it is the working that
strengthens them (unless taken too far).
Remember that drop forged wrenches, hammers, etc. are considered
superior to their cast counterparts.
That being said, certain items need to be cast due to their form,
neccessities of production, etc. It really depends on what the
object will be used for that dictates suitabilities of manufacture.
A mid century die struck white gold wedding ring-- the "Everwed"
variety-- might be made of metal that is in the end tougher. But a
similar version of the ring, cast in the same metal but heavier in
shank cross section, etc. will last a lot longer due to its larger
