Laser Cutting Kovar from VT machining delivers precision Kovar parts produced to your exact drawing. Fiber laser cutting melts and ejects metal along a programmed path, producing a narrow kerf and a clean, near burr-free edge, and we tune every parameter to the behaviour of Kovar, which is matched thermal expansion for glass/ceramic seals.
Laser Cutting Capability for Kovar
- Fiber source 1–6 kW
- Kerf width 0.1–0.3 mm
- Contour tolerance ±0.05 mm
- Assist gas (N₂/O₂) selected per alloy
How Laser Cutting Kovar Works
A focused fibre-laser beam melts and blows material from the Kovar sheet along the programmed contour. Power, focal position, nozzle stand-off and assist-gas pressure are tuned to the alloy and thickness for a clean, square edge.
Every job begins from your CAD model or 2D drawing. Fixturing and tool paths are planned so the most critical dimensions are produced in the most rigid, repeatable setup. Critical dimensions are checked on the first part and monitored through the run.
Laser Cutting Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on Kovar parts are checked in-process and verified at final inspection using calibrated instruments and, where required, CMM measurement. Full documentation — dimensional reports, mill certs, FAIR — is available when your programme needs it.
Design Tips for Laser Cutting Kovar
A few design choices make a real difference to cost and quality. Keeping holes no smaller than the material thickness, allowing for kerf, and grouping features sensibly improves edge quality and nesting yield on Kovar. If you send your model early, we will return practical DFM feedback before you commit to production.
Laser Cutting Tolerances & Surface Finish
Laser-cut Kovar holds contour tolerances around ±0.05 mm depending on thickness, with a narrow kerf and a clean, near burr-free edge.
Final tolerances are governed by the material's behaviour, wall thickness and overall stiffness. We give honest DFM feedback if a callout would be costly or better achieved another way.
Working with Kovar
Kovar offers a useful combination of properties: it is matched thermal expansion for glass/ceramic seals. Those characteristics shape how we approach laser cutting — from tool and parameter selection to work-holding and coolant.
If your application is sensitive to alloy condition, we agree the specification in writing and document it. Stock is sourced from reputable suppliers so what you order is what you receive.
Secondary Operations & Finishing
We complete Kovar components with the secondary steps your drawing calls for. We arrange heat treatment, surface treatment, marking and assembly as needed. Tell us the final spec and we will plan the full route so parts arrive ready to use.
Applications of Laser Cutting Kovar
Laser Cutting of Kovar supports parts across aerospace, medical, automotive, electronics, semiconductor, energy and general industrial sectors. We scale from one-off prototypes to ongoing production while holding the same quality.

Request a QuoteFrequently Asked Questions
What tolerances can you hold for Laser Cutting Kovar?
Achievable tolerances for Kovar cutting depend on the alloy, geometry and feature size. Laser cutting holds contour tolerances to around ±0.05 mm depending on thickness. Exact figures are confirmed against your drawing callouts.
What surface finish is achievable on Kovar with Laser Cutting?
Laser cutting leaves a clean cut face on Kovar with a small heat-affected zone; most parts need little secondary finishing.
Which industries use Laser Cutting Kovar parts?
Laser Cutting Kovar parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise Kovar components are required.
Does Laser Cutting Kovar require dedicated tooling?
Most Kovar cutting work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
Why is Kovar a good choice for Laser Cutting?
Kovar is matched thermal expansion for glass/ceramic seals, which makes it well suited to Laser Cutting. We tune the process to the alloy so the finished Kovar cutting part meets your dimensional and functional requirements.
What is Laser Cutting Kovar and how is it done?
Laser Cutting Kovar refers to fiber laser cutting melts and ejects metal along a programmed path, producing a narrow kerf and a clean, near burr-free edge. Applied to Kovar — matched thermal expansion for glass/ceramic seals — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
