VT machining provides Laser Cutting Invar for customers who need accurate, repeatable Invar components. Because Invar is ultra-low thermal expansion, we adapt the process to suit — controlling the variables that matter for this alloy.
Laser Cutting Capability for Invar
- 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 Invar Works
A focused fibre-laser beam melts and blows material from the Invar 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.
We start from your supplied geometry and tolerance scheme. The setup is designed to minimise re-clamping, which protects positional accuracy across features. A first article is verified against the drawing before the balance of the batch is released.
Laser Cutting Tolerances & Surface Finish
Laser-cut Invar holds contour tolerances around ±0.05 mm depending on thickness, with a narrow kerf and a clean, near burr-free edge.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
Secondary Operations & Finishing
Most Invar parts need some finishing, which we manage in-house or through vetted partners. Options include deburring and edge-breaking, heat treatment, surface grinding, polishing, and plating or anodising for corrosion resistance and appearance. Give us the finished-part requirement and we will sequence every operation correctly.
Laser Cutting Quality & Inspection
Quality is built in, not inspected on. We monitor key features during the run and confirm them at final inspection, with CMM verification available for tight tolerances. We provide the inspection and traceability records your quality system requires.
Design Tips for Laser Cutting Invar
Small design adjustments often cut cost and lead time. Keeping holes no smaller than the material thickness, allowing for kerf, and grouping features sensibly improves edge quality and nesting yield on Invar. If you send your model early, we will return practical DFM feedback before you commit to production.
Working with Invar
Invar is ultra-low thermal expansion. We translate those properties into a process plan: the right tooling, speeds, feeds and fixturing for the alloy.
Where the grade, temper or heat-treat condition matters to performance, we confirm it with you and can supply material certificates. Material is procured to recognised standards for consistent, repeatable results.
Applications of Laser Cutting Invar
Invar parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.
How to Order Laser Cutting Invar
Starting your project takes one email. Send your CAD or 2D drawing, the Invar grade and condition, the quantity and any finish or inspection requirements. We respond quickly with price, lead time and any DFM notes, in clear English.

Why is Invar a good choice for Laser Cutting?
Invar is ultra-low thermal expansion, which makes it well suited to Laser Cutting. We tune the process to the alloy so the finished Invar cutting part meets your dimensional and functional requirements.
What is the typical lead time and minimum order for Laser Cutting Invar?
Laser Cutting prototypes for Invar can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
What tolerances can you hold for Laser Cutting Invar?
Achievable tolerances for Invar 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.
How clean are the edges produced by Laser Cutting on Invar?
Laser cutting leaves Invar with a narrow kerf and a clean, near burr-free edge and only a small heat-affected zone.
