Applications in Hermetic Engineering
High-Temperature Assemblies
Ideal for structural parts exposed to sustained heat, such as brazed joints in aerospace, industrial, or defense systems.
Wear-Resistant Components
TiB₂'s hardness extends component lifespan in valves, plungers, and feedthroughs operating in abrasive environments.
Electrical Contacts and Electrodes
Used in hermetic connectors and vacuum environments for its high conductivity and arc-resistance under extreme loads.
Corrosion-Resistant Barriers
Protective barrier against aggressive chemicals, acids, and reactive gas exposure in sealed process environments.
Thermal Spreaders
TiB₂ efficiently distributes heat in compact sensor housings and brazed subassemblies operating under power load.
Advanced Brazing Fixtures
Stable at high temperatures and chemically inert—ideal for reusable tooling in high-vacuum or furnace environments.
