Ductility (Elongation) is greatly improved by the MC process.
Strength levels are comparable to or greater than similar alloys produced by other processes.

Toughness values are dramatically greater than the minimum requirements and exceed the levels which can be achieved by other wires. This is the result of the ultra-low impurities which can be achieved by the MC process.
