Molybdenum Plate

Molybdenum Plate is made of high-purity molybdenum material, possessing excellent thermal conductivity, low thermal expansion, and corrosion resistance. They are commonly applied in high temperatures and pressure conditions. Its thickness ranges from 0.09″ to 3″. HM can supply high-precision molybdenum and molybdenum alloy plates with tight tolerances and various specifications.

Molybdenum Plate Specifications

Thickness (inch)	Max. Width (inch)	Max. Length (inch)	Thickness Tolerance (inch)
0.090 – 0.200	30	114	+/- 0.008
0.200 – 0.250	24	84	+/- 2%
0.250 – 0.500	24	42	+/- 2%
>0.500	24	–	+/- 2%

Molybdenum Sheet

Molybdenum Sheet has similar properties to molybdenum plates, but the thicknesses range from 0.004″ to 0.09″. It is better suited for applications requiring lightweight and high strength.

Molybdenum Disc

Molybdenum Discs are available in pure form or coated with materials such as Ruthenium (Ru), Rhodium (Rh), Nickel (Ni), Silver (Ag), Gold (Au), etc. Molybdenum discs serve as crucial contact materials in silicon-controlled rectifier diodes, transistors, and thyristors. Additionally, molybdenum discs are essential heat sink base materials in integrated circuits (ICs), large-scale integrated circuits (LSIs), and hybrid circuits.

Molybdenum Disc Specifications

Dimension:	Diameter: 5-150 mm Thickness: 0.2-12.0 mm Tolerance: ±0.025 mm
Flatness:	<0.005 mm
Parallelism:	<0.01 mm
Roughness:	Ra<0.063 mm
Plating:	Ru, Rh, Ni, Ag, Au, etc.

Molybdenum Plate/Sheet/Disc Production Process

Raw Material: Select high-purity molybdenum powder.
Powder Metallurgy: Mix with binder and compact into a green billet.
Sintering: High-temperature sintering to remove the binder and increase density.
Heat Treatment: Anneal to relieve stress and enhance properties.
Surface Treatment: Clean and polish the surface.
Cutting & Customization: Cut or customize according to requirements.

Molybdenum Plate/Sheet/Disc Processing Method

Sintering
Forging
Rotary Forging
Rolling
Polishing

Molybdenum Plate/Sheet/Disc Surface Finish

Depending on the intended applications, molybdenum plate, sheet, and disc have three main surface finishes as follows:

Black: The surface is “as swaged” or “as drawn”, retaining a coating of processing lubricants and oxides.
Cleaned: The surface is chemically cleaned to remove all lubricants and oxides.
Ground: The surface is centerless ground to remove all coating and to achieve precise dimensions control.

Molybdenum Plate/Sheet/Disc Applications

Aerospace: Molybdenum plates, sheets, and discs can be used to manufacture engines, combustion chambers, and other components.
Chemical Field: Molybdenum plates, sheets, and discs can be used to manufacture parts for high-temperature furnaces, reactors, heat exchangers, and other equipment.
Electronics: Molybdenum plates, sheets, and discs can be used to manufacture electronic devices and heat-dissipation materials. Molybdenum discs are the ideal material for Heat Sink Bases in ICs, LSIs, and Hybrid circuits.
Medical Field: Molybdenum plates and sheets can be used to make radiation protection equipment, containers for transporting radioactive isotopes, etc.

Molybdenum Plate/Sheet/Disc Packaging

The Molybdenum Plate/Sheet/Disc is carefully placed in wooden cases or cartons with additional support from soft materials to prevent any shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
