Heeger Materials supplies Molybdenum Plate in pure molybdenum, TZM, and MoLa materials for high-temperature, vacuum, furnace, semiconductor, electronic, tooling, and precision-machining applications.
Standard plate thickness begins above approximately 0.1875", with widths up to 800 mm and lengths up to 3200 mm, depending on material grade, thickness, surface condition, tolerance, and quantity.
Custom cutting, machining, flatness, thickness tolerance, and surface requirements can be reviewed according to customer drawings.


| Material | Key Characteristics | Typical Selection |
|---|---|---|
| Pure Molybdenum | High purity, low thermal expansion, good thermal conductivity | General furnace, vacuum, electrode and machined plate applications |
| TZM Alloy | Higher elevated-temperature mechanical strength than pure Mo | High-load tooling, furnace fixtures and structural components |
| MoLa | Improved high-temperature structural stability compared with pure Mo | Heat shields, furnace assemblies and selected thermal applications |
Material selection depends on operating temperature, atmosphere, mechanical load, machining requirements, and final component geometry.
Molybdenum plates are used for furnace parts, heat shields, tooling, vacuum components, electrodes and high-temperature structures. Key specifications include thickness, width, length, flatness, purity, surface finish and working atmosphere. Molybdenum is useful where strength and stability are needed at elevated temperature.
Compare molybdenum sheets, molybdenum rods and molybdenum crucibles. Broader options are listed under molybdenum products.
What information helps quote molybdenum plates? Please provide thickness, dimensions, quantity, tolerance, surface condition and any drawing or application environment.
Heeger Materials supplies pure molybdenum Type 361, TZM Type 364, and MoLa plate, with other grades available subject to specification and manufacturing capability.
ASTM B386/B386M covers molybdenum and molybdenum-alloy plate, sheet, strip, foil, and ribbon. The current active edition is ASTM B386/B386M-25.
The current plate page defines molybdenum plate as material above approximately 0.1875" thickness, with custom thicknesses available according to grade, dimensions, and quantity.
Current listed capability is up to approximately 800 mm width and 3200 mm length, depending on thickness, alloy, tolerance, and surface requirements.
On the current Heeger Materials product structure, plate is used for thicknesses above approximately 0.1875", while thinner material is directed to the molybdenum sheet product page.

*If the width is <6”, please check the Molybdenum strip/foil. If the thickness is <0.1875”, please check the Molybdenum sheet.
Molybdenum plates are packed in protective wooden cases or other suitable export packaging. Soft separators and supports are used to reduce plate movement, edge impact, surface contact, and transport damage.
Special packaging can be provided for precision-ground, machined, large-format, or tight-flatness plates.

The following sizes represent commonly listed Type 361 molybdenum plate configurations. Current stock, available quantity, surface condition, and lead time should be confirmed before ordering.
