Applications in Hermetic Engineering
Aerospace Heat Zones
Used in turbine-mounted enclosures and engine sensor mounts exposed to extreme vibration, pressure, and heat.
Chemical Process Equipment
Inconel 625 performs reliably in reactors, pumps, and feedthroughs exposed to nitric, sulfuric, and hydrochloric acids.
Marine & Subsea Electronics
Provides long-term corrosion resistance in saltwater environments, ideal for pressure vessels and sealed underwater connectors.
Power Generation Systems
Utilized in sealed monitoring systems for nuclear and thermal plants due to high-temperature and radiation resistance.
Vacuum Furnaces & Brazing Fixtures
Inconel’s thermal integrity makes it suitable for structural components inside high-vacuum or high-temperature brazing chambers.
Hermetic Sensor Housings
Used in sealed sensor packages requiring high strength, corrosion resistance, and stability over thermal cycles.
