BOMO METALS · MADE TO YOUR REQUIREMENTS
Custom Tungsten Crucibles
Drawing-based tungsten crucibles for specified thermal-process requirements. Submit the tungsten grade, internal and external geometry, wall and base details, charge material and operating conditions for a custom quotation.
Tungsten material properties & specification reference
Tungsten is a dense refractory metal with a high melting-point reference. Pure tungsten, tungsten heavy alloys and tungsten carbide are separate material systems; a familiar product shape does not make their properties interchangeable.
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 | Tungsten (W) | Element reference; identify the industrial grade separately |
| Atomic number | 74 | Element identity |
| Density at room temperature | 19.3 g/cm³ | Reference for the element; delivered material depends on grade and condition |
| Melting point | 3414 °C | Element phase-change reference, not a continuous service-temperature rating |
| Common designation in our materials | W1 | 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 tungsten crucibles
A tungsten crucible enquiry should define both the process container and its operating context. Diameter and height alone leave the internal cavity, wall profile, base and installation requirements unresolved. A section drawing is the clearest way to describe the finished geometry.
The tungsten product material describes crucibles processed to drawings. The selected route and achievable requirements depend on the actual material and geometry. The example photograph illustrates an open-cup geometry; its material grade and dimensions are established by the project specification.
Customization options & quotation inputs
| Customization input | What to specify | Details for review |
|---|---|---|
| Tungsten specification | Required grade, chemistry and material standard | Any process-contact or contamination requirements |
| Container geometry | Inner and outer dimensions, height and cavity shape | Wall thickness, base thickness, corners and critical tolerances |
| Installation | Support, rim, lid or mating interfaces where relevant | Furnace drawing, clearances and handling details |
| Acceptance requirements | Surface, cleanliness and requested inspection | Documentation scope and checks agreed before production |
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
Tungsten crucible enquiries relate to a defined heating or material-processing operation. Specify what the container will contact and how it is heated. General tungsten uses such as electrodes or counterweights do not establish a crucible performance specification.
Provide the charge composition, atmosphere, thermal cycle and equipment arrangement. The material melting point must not be used as the crucible working-temperature limit. Compatibility, contamination, geometry and service requirements need a combined review for the particular application.
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.
Tungsten Crucibles questions
Is a tungsten crucible a direct replacement for a molybdenum crucible?
Do not assume a direct replacement. Material, heating behaviour, process contact and assembly requirements differ. Provide the original specification and process conditions so the proposed material can be reviewed.
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 tungsten crucibles quotation
Email your drawing, sketch or initial requirements to sales@bomometals.com. Include the following information where available:
- Section drawing, inner/outer dimensions, wall/base thickness, charge, atmosphere and heating/support arrangement.
- 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.
