HiFIRE fuseheads consist of two tin-coated metal lamellas embedded in a polymer chamber. They are clamped and welded to ensure a firm mechanical connection and guarantee contact between the bridge wire and metal lamellas, under any conditions. The bridgewire is coated in a primary and secondary reactive high-energy pyrotechnic composition. Special coating systems tailored to each specific application provide protection against mechanical, chemical and thermal damage, as well as environmental factors. Depending on your requirements, the fusehead leg wires can be executed in different ways and connected via crimping, soldering or welding. The reactivity of pyrotechnics can range from extremely high to moderate based on the design and installation of a device and the intended effect.
Thanks to the range of opportunities afforded by our pyrotechnic production, we can also offer you customised solutions including pyrotechnic substances free from heavy metals and halogen, or fuseheads for use in up to 260°C.
