Can someone say me where the other 6 are? So I got those:

 

- Area outside of the TWTNW castle- 100 Acre Woods- Twilight Town in Sunset Terrace- Handed over 60 materials to the Moogle- Atlantica- Goddess Cup- Space Paranoids

There are no more, you need to use a material to halve the cost of the weapon

There are only 6 Orichalcum + to find in the game.

 

In order to create the Ultima Weapon, which needs 13 Orichalcum +,  you have to use an Energy Crystal. This will divide the needed materials by two, therefore letting you create the Ultima Weapon with only 7 Orichalcum +.

Use an Energy Crystal to halve the cost. Those book heartless outside of Merlins house drop them.
