Review pure-molybdenum flat stock and disc options, or specify TZM separately. Send your dimensions, surface, material condition and quantity for a configuration-specific quotation.
Select a flat-stock or disc geometry, then confirm the grade, manufacturing condition and finished dimensions. Photographs show existing catalogue configurations.
Provide thickness, width and length, together with flatness, surface and machining-allowance requirements. Rolled and polished size references are listed below.
Provide diameter, thickness, flatness, edge details and material condition. Confirm the starting product form and the applicable material and drawing requirements.
| Parameter | Published catalogue reference / RFQ confirmation |
|---|---|
| Material options | Molybdenum (Mo); separately specified TZM alloy. |
| Published pure-Mo option | 99.95% minimum. Confirm the purity basis and required certificate for the offered material. |
| Density reference | 9.8–10.2 g/cm³; confirm the manufacturing route and material state. |
| General flat-stock envelope | Thickness 0.05–40 mm × width 10–800 mm × length 10–2,000 mm. |
| Flat-stock surface options | Rolled, polished, ground or chemically cleaned. |
| Surface appearance references | Shiny, matte, satin or as-rolled; agree the required finish rather than relying on the appearance label alone. |
| Disc envelope | Diameter ≤1,500 mm × thickness 0.1–1.0 mm. Confirm the feasible diameter/thickness combination. |
| Disc condition / finish references | Rolled, cold rolled, turned or ground; agree the required condition and finished surface. |
These dimensions are catalogue enquiry envelopes. The rolled and polished size tables below are separate references and include different length listings. Confirm the actual size combination, quantity, material condition and inspection criteria during quotation.
Specify TZM chemistry and condition separately from pure-Mo purity. ASTM B386/B386M covers plate, sheet, strip, foil and ribbon; ASTM B387/B387M covers bar, rod and wire. For a disc or a finished machined part, confirm the starting form, ordered standard edition and drawing requirements.
Compare the existing catalogue size bands, then state the required dimensions explicitly. “L” is retained from the original table as an unspecified length; it must be confirmed in the quotation.
| Thickness(mm) | Width(mm) | Length(mm) |
|---|---|---|
| 0.05 ~ 0.10 | 150 | L |
| 0.10 ~ 0.15 | 300 | 1000 |
| 0.15 ~ 0.20 | 400 | 1500 |
| 0.20 ~ 0.30 | 650 | 2540 |
| 0.30 ~ 0.50 | 750 | 3000 |
| 0.50 ~ 1.0 | 750 | 5000 |
| 1.0 ~ 2.0 | 600 | 5000 |
| 2.0 ~ 3.0 | 600 | 3000 |
| > 3.0 | 600 | L |
| Thickness(mm) | Width(mm) | Length(mm) |
|---|---|---|
| 1.0 | 50 | 100 |
| 2.0 | 80 | 150 |
| 3.0 | 400 | 600 |
| 4.0-5.0 | 400 | 600 |
| 5.0-10.0 | 600 | 1200 |
| > 10.0 | 600 | 1600 |
The listings describe alternative catalogue configurations. They do not establish stock availability, every possible size combination, or a manufacturing route for each item. For thin rolled stock, also review Molybdenum Sheet & Foil.
The existing Mo-1, Mo-2 and Mo-3 catalogue table is reproduced below. Specify the required chemistry, reporting basis and acceptance limits for the ordered product. These catalogue labels are not an automatic equivalence to an ASTM grade or a lot-analysis certificate.
| Content | Mo | Fe | Ni | Al | Si | Ca | Mg | P | C | O | N | Other |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Mo-1 | 99.95 | 0.005 | 0.002 | 0.002 | 0.003 | 0.002 | 0.001 | 0.001 | 0.005 | 0.003 | 0.001 | - |

For heat shields, trays or support parts, include temperature, dwell, atmosphere, mounting and loading. Review oxidation exposure and the operating cycle for the proposed assembly.
For heat-spreading, semiconductor or vacuum-equipment parts, include dimensions, flatness, cleanliness, surface and contamination requirements.
For glass, ceramics, aerospace testing or research fixtures, send the drawing, material condition, mating components and inspection requirements.
Material selection and the required working or annealed condition depend on the actual design. A high melting point does not establish the allowable component temperature or service life.
Products are identified and protectively packed for storage and transport. State any additional surface protection, cleanliness, inspection record or packaging requirement in your enquiry.
Yes, request TZM explicitly and provide the required alloy chemistry, condition and documents. The pure-Mo purity reference is not the material definition for TZM.
They are separate catalogue references. Confirm the actual thickness, width and length combination and required quantity. An entry marked “L” does not define an ordered length.
No. ASTM B387/B387M covers bar, rod and wire, while ASTM B386/B386M covers flat mill products. For a disc, confirm the starting form, material grade, ordered standard edition and finished drawing requirements.
Provide the product form, material and grade, dimensions, tolerances, surface, flatness, material condition, quantity and drawing revision. Include operating conditions, inspection documents and delivery requirements where relevant.
Review thin rolled product forms and specify thickness, condition and rolling-direction requirements.
For round stock or a rod-based machined part, review diameter, length, material condition and drawing requirements.
Choose a separately defined TZM alloy and product form when its material specification suits the design.
Explore example uses in furnace, process-equipment and research assemblies, then define the requirements of your own component.
Review material naming before specifying the grade, chemistry, product form and condition for a quotation.
Send the material grade, product form, dimensions, quantity and drawing. Add the surface, condition, operating requirements and documents needed for the order.
