A **titanium diaphragm** is the premium driver element in many industrial [sonic horns](/glossary/sonic-horn). Titanium's high strength-to-weight ratio, fatigue resistance and corrosion immunity to most flue-gas chemistries make it the longest-lived diaphragm material available.

## Service life

A well-installed titanium diaphragm in typical industrial duty lasts 3–5 years of continuous service before replacement, with shorter life in particularly aggressive (high-chloride, high-temperature) applications and longer life in cooler or less corrosive duty. The [stainless-steel](/glossary/aisi-316-316l-stainless) alternative typically lasts 1.5–3 years in the same service.

## Replacement is straightforward

A scheduled [diaphragm replacement](/glossary/diaphragm-replacement-sonic-horn) is a routine planned-maintenance task typically completed in under an hour per horn during a normal outage. Diaphragm degradation shows up as gradual SPL drift — instrumented horns flag the trend before output drops materially.
