Kovar Micro Machining
Precision CNC micro machining for Kovar (ASTM F15 / Fe‑Ni‑Co alloy) parts built for hermetic sealing and high‑reliability performance. From early prototypes to repeat production, KELTRYN helps engineering and sourcing teams turn complex designs into manufacturable, consistent, and fully traceable components.
KELTRYN specializes in the unique challenges of Kovar machining—controlling heat, preventing work hardening, managing burrs, protecting thin‑wall geometries, and preserving critical sealing features—to deliver parts that meet tight dimensional, cosmetic, and functional requirements.
Why KELTRYN for Kovar Micro Machining
Built for Hermetic Applications
We focus on features that matter for sealing: flatness-sensitive lands, sealing steps, grooves, and precision fits for glass‑to‑metal and ceramic‑to‑metal interfaces.
Process Control for Difficult Alloys
Kovar and Fe‑Ni‑Co alloys demand careful heat and chip control. Our approach minimizes work hardening, edge deformation, and surface damage on small and thin features.
Burr‑Controlled Precision
Repeatable deburring strategies protect sharp edges and sealing surfaces, reducing leak risk and assembly issues.
Thin‑Wall & Small‑Feature Expertise
Fixturing, toolpaths, and cutting parameters are tuned to protect thin sections and micro features without compromising dimensional accuracy.
Engineering Partnership
Practical DFM feedback before cutting chips—so features, tolerances, and finishes align with reliable machining outcomes.
Traceability & Documentation
Material certifications, lot traceability, and inspection reporting support high‑reliability, regulated, and audit‑ready programs.
