Custom Molybdenum Rods & Bars
Molybdenum rods and bars for machining blanks, supports, lead-out parts and specified thermal components. Share the grade, diameter, length, surface condition and critical features for review and quotation.
Molybdenum material properties & specification reference
Molybdenum is a refractory metal used in specified thermal and equipment components. Its lower density relative to tungsten can be relevant to an assembly design. Pure Mo, carbide-strengthened TZM and lanthanum-oxide-dispersed MoLa must be treated as separate material specifications.
Thermal operating context
Specify vacuum or gas atmosphere, exposure to air, thermal cycles, load and contact media. Melting point is not an operating-temperature guarantee.
Drawing-based geometry
Define critical dimensions, datum surfaces, finish and inspection requirements for the actual component.
| Property / specification | Reference or selection | Procurement meaning |
|---|---|---|
| Material identity | Molybdenum (Mo) | Element reference; identify the industrial grade separately |
| Atomic number | 42 | Element identity |
| Density at room temperature | 10.2 g/cm³ | Reference for the element; delivered material depends on grade and condition |
| Melting point | 2622 °C | Element phase-change reference, not a continuous service-temperature rating |
| Common designation in our materials | Mo1 | Use the exact material grade or standard required by your drawing |
| Purity reference in product files | ≥99.95% for specified pure-metal examples | Confirm required chemistry and certificate scope for the order; not applied to alloys |
| Delivered shape and condition | Drawing-based | Geometry, finish and material state are specified separately |
Element density and melting point: Royal Society of Chemistry reference. Designation and purity examples: our product materials. Reference values explain the base metal; the selected grade and agreed order specification govern delivery.
What to specify for molybdenum rods
A molybdenum rod enquiry starts with the intended use: material for your own machining, a support member or a finished part with end details. Diameter and length do not fully define a rod when straightness, surface condition or a mating fit affects its function.
The rod materials describe forging, rotary swaging, straightening and turned or ground conditions. The route is reviewed for the required grade, size and quantity. Tell us which surfaces will be machined later and which dimensions must be accepted as delivered.
Customization options & quotation inputs
| Customization input | What to specify | Details for review |
|---|---|---|
| Material | Pure molybdenum, or named TZM/MoLa requirements | Grade and standard; alloys are separately specified |
| Rod geometry | Diameter, length and end shape | Straightness, roundness and critical diameter tolerance |
| Delivered condition | As-produced, cleaned, turned or ground options to discuss | Finish and any further machining allowance |
| Finished features | Threads, steps, holes or flats | Drawing revision, mating dimensions and inspection points |
These fields describe your requirements, rather than a fixed stock catalogue or a universal capability range. The selected material, geometry, quantity and inspection scope are reviewed together.
Applications & operating conditions
Our materials list rod uses in electric-vacuum parts, supports, electrodes, lead-out parts and heating rods. These are distinct duties. For an electrode enquiry, include the electrical and process requirements; for a heater, include the thermal and electrical design rather than specifying rod dimensions alone.Material selection for a thermal rod requires the temperature cycle, atmosphere and load. Identify the specified grade if the equipment drawing calls for TZM or MoLa. Avoid treating an alloy designation as another name for pure molybdenum.
Agree the manufacturing and inspection scope
Start with a current drawing, material specification and the features that determine fit or function. Identify any surfaces, connections or operating conditions that need special review. The proposed manufacturing route and achievable requirements are discussed before the order scope is agreed.
List the material documentation and dimensional or surface checks your procurement process requires. Their availability and acceptance criteria should be agreed in the quotation. For a repeat order, identify changes to the drawing, material or service conditions.
Molybdenum Rods questions
Can a molybdenum rod be quoted as a finished component?
Yes, a drawing-based enquiry can include steps, threads or other defined features. State whether you need a machining blank or a finished part, and mark the dimensions that control fit and function.
Can I request non-standard dimensions?
Yes. Send the required dimensions and mark the tolerances that matter for your application. We review the actual material, geometry and quantity; the photographs are not fixed-size or stock listings.
What are the lead time and documentation options?
Include your required schedule and documents with the enquiry. The inspection scope, production route, quantity and delivery requirements are reviewed before quotation; one lead time is not promised for all custom parts.
Request a molybdenum rods quotation
Email your drawing, sketch or initial requirements to sales@bomometals.com. Include the following information where available:
- Diameter and length; straightness/roundness needs; end details, finish and machining allowance.
- Material grade or standard, drawing revision and component function.
- First-order quantity, expected repeat demand and required inspection or material documents.
- Operating conditions, delivery country and location, and requested schedule.
We review the achievable specification, inspection scope, packaging and quotation terms for your project. A photograph can start the discussion; dimensioned information is needed to define manufacture.
