Molybdenum Material Data
| Density | 10.22 g/cm³ |
|---|---|
| Tensile strength | 550–900 MPa |
| Yield strength (0.2%) | 480 MPa |
| Hardness | 200–250 HV |
| Melting point | 2623 °C |
| Thermal conductivity | 138 W/m·K |
| Thermal expansion | 4.8 ×10⁻⁶/K |
| Electrical conductivity | 34% |
| Machinability (C36000 = 100%) | 30% |
| Grades we run | Pure Mo (99.95%), TZM, Mo-La, MoCu |
Published typical values for Pure Mo / TZM. Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
Below its ductile-to-brittle transition it chips rather than cuts. Sharp corners get a radius, and thin sections are wire-EDM cut instead of milled.
How CNC Plasma Cutting Molybdenum Works
A focused fibre-laser beam melts and blows material from the Molybdenum 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.
Achievable Tolerances for CNC Plasma Cutting Molybdenum
| Feature | Standard | Precision |
|---|---|---|
| Contour dimension | ±0.10 mm | ±0.05 mm |
| Hole diameter | ±0.10 mm | ±0.05 mm |
| Kerf width | 0.20 mm | 0.10 mm |
| Squareness of cut edge | 0.5° | 0.2° |
| Heat-affected zone | 0.15 mm | 0.05 mm (N₂ assist) |
| Minimum hole diameter | 1.2 × thickness | 1.0 × thickness |
| Edge condition | light dross | burr-free, N₂ cut |
Standard is what a normal quotation assumes. Precision is available on nominated features and is priced separately, because it needs extra setups, in-process gauging and CMM verification. Call out only the features that need it — blanket-tightening a drawing is the single most common reason a quote comes back expensive.
CNC Plasma 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.
Working with Molybdenum
Molybdenum is very high melting point and thermal stability. 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.
CNC Plasma Cutting Tolerances & Surface Finish
Laser-cut Molybdenum 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 Molybdenum 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.
Design Tips for CNC Plasma Cutting Molybdenum
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 Molybdenum. If you send your model early, we will return practical DFM feedback before you commit to production.
Applications of CNC Plasma Cutting Molybdenum
Molybdenum 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 CNC Plasma Cutting Molybdenum
Starting your project takes one email. Send your CAD or 2D drawing, the Molybdenum 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.

What We Need to Quote CNC Plasma Cutting Molybdenum
- GeometrySTEP or IGES for the 3D model, plus a PDF drawing if you have tolerance callouts. A dimensioned sketch is enough to start.
- MaterialThe exact Molybdenum grade and condition — temper, heat-treat state or hardness. If you are not sure, tell us the function and we will suggest one.
- QuantityPrototype count and the expected annual volume. Both change how the part is made and therefore what it costs.
- TolerancesWhich features are critical. Everything else runs to our standard tolerance, which is what keeps the price sensible.
- FinishSurface treatment, cosmetic requirements, and any faces that must be masked.
- DocumentsWhether you need a material certificate, dimensional report, FAIR or PPAP with the shipment.
Missing something from the list is not a problem — send what you have. We will come back with the specific questions rather than a generic form.

What is the typical lead time and minimum order for CNC Plasma Cutting Molybdenum?
CNC Plasma Cutting prototypes for Molybdenum 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 is CNC Plasma Cutting Molybdenum and how is it done?
CNC Plasma Cutting Molybdenum refers to cNC plasma cutting uses an ionized gas jet to sever thicker conductive plate at high speed. Applied to Molybdenum — very high melting point and thermal stability — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
What material thickness or size range suits CNC Plasma Cutting Molybdenum?
Laser-cut Molybdenum thickness depends on the alloy and its reflectivity; we tune the fiber source and assist gas accordingly.
Why is Molybdenum a good choice for CNC Plasma Cutting?
Molybdenum is very high melting point and thermal stability, which makes it well suited to CNC Plasma Cutting. We tune the process to the alloy so the finished Molybdenum cutting part meets your dimensional and functional requirements.
