    摘要: Provided is an ignition plug used for an internal-combustion engine. The ignition plug includes: a center electrode; an insulator disposed outside the center electrode; a metal housing disposed outside the insulator; a ground electrode having an end connected to the metal housing and the other end facing the center electrode; and an electrode tip fixed to one or more of the center electrode and the ground electrode. The electrode tip is made of an alloy of iridium Ir, hafnium Hf, and niobium Nb. Therefore, the ignition plug with the low-cost iridium can have high resistance to prevent an iridium element from oxidizing and vaporizing in high speed driving conditions.
