Applying materia is like aetherically enhancing one's gear. It is extremely common in Eorzea for combatants to utilize aether to enhance their attacks (just look at pretty much every ability for every class/job). It stands to reason that materia affixed to one's weapon could boost the raw power of the aether channeled with it. Rather than affecting the physical properties of the weapon, it's affecting one's magical attunement.

"Song dogs barking at the break of dawn, lightning pushes the edges of a thunderstorm; and these streets, quiet as a sleeping army, send their battered dreams to heaven."
