Resistance Wires for (Airbag) Initiators

Resistance wires made of platinum alloys are the material of choice when it comes to reliability and reproducibility –

as an airbag initiator to trigger the front or side airbags, in the seat belt tensioner, on the engine hood, and in the battery circuit breaker. The bridge wire is also used in military technology, pyrotechnology, and electronic ignition systems for blasting applications.
