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 Honing Molybdenum Works
Abrasive media or tooling refine the Molybdenum surface in controlled stages, removing the previous step's marks until the target roughness and edge condition are reached.
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.
Achievable Tolerances for CNC Honing Molybdenum
| Feature | Standard | Precision |
|---|---|---|
| Surface roughness | Ra 0.8 µm | Ra 0.05 µm |
| Edge break | 0.1–0.3 mm | 0.05 ±0.02 mm |
| Material removed | 0.02 mm | 0.005 mm |
| Bore roundness after honing | 0.005 mm | 0.002 mm |
| Cross-hatch angle | 45° ±10° | 45° ±5° |
| Cosmetic grade | uniform satin | mirror, no visible lines |
| Masking of datum faces | on request | standard |
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 Honing Tolerances & Surface Finish
Finishing brings Molybdenum to a defined roughness target — from a uniform satin to Ra values as low as 0.05 µm — with controlled, repeatable edge breaks.
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 Molybdenum
Molybdenum offers a useful combination of properties: it is very high melting point and thermal stability. Those characteristics shape how we approach finishing — 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.
Design Tips for CNC Honing Molybdenum
A few design choices make a real difference to cost and quality. Telling us the target Ra, the cosmetic faces and any masking needs lets us finish Molybdenum efficiently without over-processing. If you send your model early, we will return practical DFM feedback before you commit to production.
Secondary Operations & Finishing
We complete Molybdenum 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.
CNC Honing Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on Molybdenum 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.
Applications of CNC Honing Molybdenum
CNC Honing of Molybdenum 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.
How to Order CNC Honing Molybdenum
Ordering Molybdenum parts is straightforward. Provide the drawing, material, quantity and any certification needs. Our engineers reply — in English — with feasibility, pricing and a realistic lead time, usually within one business day.

What We Need to Quote CNC Honing 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.
