Metal fixing material leadthrough having low susceptibility to faults

A metal fixing material leadthrough for an igniter of at least one of airbags or belt tensioners, the metal fixing material leadthrough comprising:

• a main body having a through-opening formed therein and an upper side;
• and
• at least one metal pin fused into a glass or glass-ceramic fixing material in the through-opening and having a core region, the at least one metal pin, at least in its core region, and the main body, at least on its upper side, are made out of stainless steel made to the EN 10020 standard, the stainless steel of the at least one metal pin and of the main body is selected in such a way that the stainless steel of the at least one metal pin and of the main body form a passivation film on its surface, wherein the at least one metal pin and the main body are made of a compatible material combination in such a way that, at least one of when an ignition bridge is installed or when the upper side is covered with a conductive film, at least one of an anode reaction or a cathode reaction does not occur or occurs only to a small extent on the upper side of the main body, wherein the stainless steel of the at least one metal pin is selected in such a way that, when converted to a standard dimensioning of a metal pin diameter of 1.00±0.03 mm and a metal pin length of 11.68±0.02 mm, the at least one metal pin has a maximum elastic deflection Wmax of at least 0.13 mm.
