Want this question answered?
Iron has more important mechanical properties.
Alloys have improved mechanical properties, hardness, resistance to corrosion, resistance to heating, stable crystalline structure etc. compared with pure metals.
Their mechanical material properties are very similar with copper coming out marginally higher in terms of yield strength. This is the amount of stress required to make the metal deform permanently.

When metal under goes mechanical working (forging) and deformation takes place, the grains in the metal get aligned in the direction of material flow. When you cut and polish the forging in the direction of material flow and macro etch, the surface will reveal fibre like structure. This is known as grain flow.
The mechanical properties of metal are usually referred to as malleability being it it bends easily like gold without breaking or shatters when struck.

Hephaestus is known for forging metal work.
Forging is a manufacturing technology. Forging is the term for shaping metal by using localized compressive forces. Cold forging is done at room temperature or near room temperature. Hot forging is done at a high temperature, which makes metal easier to shape and less likely to fracture.
Daniel Boone, with a team of frontiersmen, is credited with forging a trail through the Cumberland Gap. We are forging Bowie knives in my metal shop class. The starship Enterprise is forging new paths to destinations heretofore unknown.
Examples: strength, ductility, malleability, hardness, elaticity, flexibility, Young modulus, etc..

The material can be similar however the process defines the grain structure and physical properties of the metal. Forging shapes hot metal by compressive force, casting is performed by pouring molten material into a molded shape and sheet metal is produced by rolling through presses until the desired thickness is achieved. The desired end result determines the process utilized. Extruding is also a process to produce a different result.
Increase in hardness and strength, decrease in ductility.
Not all metals are so strong. Many polymeric materials, carbon fibers, etc. have very good mechanical properties.
