DragonQuest also explained it as "iron interferes with magic." You could neutralize iron's magic-inhibiting effects by alloying it with precious metals.I assume this person is not from D&D because if he is then he has missed the D&D explanation for the reason armour inhibits spells completely; it is nothing to do with metal and everything to do with the somatic component of spells being inhibited by wearing restrictive clothing of any kind (gauntlets etc).
The only game I ever remember using this type of explanation was MERP I think.
