No.
Just breed a Beldum, Metang or Metagross with a Ditto in the daycare, or with one of the pokemon in the Mineral egg group.
Pokefan1357 Says: For some reason, rare Pokemon(Mewtwo, Mew, Giratina, Articuno, Zapdos, Moltres...) and steel type Pokemon(Metagross, Metang, Magnemite, Magneteon...)don't have genders. This means that you can't breed them. Ditto breeding only works if the Pokemon you are breeding it with has a gender. Also, the breeding works with male Pokemon, not just female! Prism Black says : You Can Breed Metang, I have Pokemon Pearl I caught a beldum and evolved it to metang then i paired it up with a Ditto, I ran not even 400 steps before there was an egg waiting for me, it took a long time to hatch but when the egg did i had a lvl 1 Beldum. Some say it depends on the version of game, this I have not tested, but I do know you Can Breed Metang with a Ditto and get a Beldum egg
A Dragonair and a Ditto will have a Dratini egg.
NO!
