From the description on the "Your Pact Boon" sidebar on page 108... yeah I think it can be made of anything, providing it suits the flavour of the pact.
As for the *mechanical effect of being made of such materials... we'll currently they're a bit obsolete by the line:
All the damage resistances and immunity that I've seen that are overcome by adamantine or silvered weaponry is also overcome by magical weaponry.
I even did a thread covering this here:
http://www.enworld.org/forum/showth...cations-of-non-magical-weapon-immunity-and-CR
The only circumstances where I can see it mattering is if the weapon ended up within an anti-magic field whilst fighting against monsters whose damage resistance/immunity could be overcome by silvered or adamantine weapons...
Cold Iron isn't AFAIK mechanically a thing in 5E.
Adamantine Weapons are... awkwardly missing in the PHB or DMG despite mentioned in the resistances/immunities of certain monsters. (Golems, Xorn, Helmed Horror and Gargoyle)
