Does the Use of CP4 in aerospace make it special?
I mean.. these specs are designed to fulfill specific purposes. differences in hardness, ductility, operational temperatures, etc. The Titanium grades is not a scale of rarity or quality.
So.. even though CP4 is commonly used in Aerospace, that doesn't mean it'd be the ideal choice for a keyboard plate..
Grade 5 is also extensively used "in aerospace" and it's much harder than 4, because it's alloyed.
I'd say since all titanium grade would be "hard enough" why not use Grade 7 ?.. it is the most corrosion resistent.. given the sweat from our hands and oils.. that property seems more attractive..
I agree cp4 aerospace keyboard plate sounds super cool.. but i hope people arn't going into this JUST on that.. and make a fool of themselves when they meet a titanium xpert.
