Products Description
Molybdenum foil is a thin strip or foil made of high-purity molybdenum (Mo) material. It has excellent high temperature resistance, corrosion resistance, and electrical and thermal conductivity. It is widely used in electronics, aerospace, nuclear industry and other fields.
Molybdenum foil are formed by rolling the pressed and sintered molybdenum plates. Usually, 2-30mm-thick molybdenum is called molybdenum plate; 0.2-2mm-thick molybdenum is called molybdenum sheet; 0.2mm-thick molybdenum is called molybdenum foil.
Molybdenum plates with different thicknesses need to be manufactured by rolling machines with different models. The thinner molybdenum sheets and molybdenum foils have the better crimp property. When manufactured by a continuous rolling machine with tensile force and supplied in coils, molybdenum sheets and foils are called molybdenum strips.
Specifications
In the rolling process, slight oxidation of surfaces of molybdenum plates can be removed in an alkaline cleaning mode. Alkaline cleaned or polished molybdenum plates can be supplied as relatively thick molybdenum plates according to customer requirements. With better surface roughness, molybdenum sheets and foils do no need polishing in the supplying process, and can be subjected to electrochemical polishing for special needs. We can machine molybdenum plates, and can supply goods in the forms of round and square molybdenum.

Features
High melting point: Molybdenum has a melting point of up to 2620°C, which is suitable for high temperature environments (such as vacuum furnaces, semiconductor equipment).
Good thermal/electrical conductivity: The conductivity is about 30% of copper, but the stability is better at high temperatures.
Low thermal expansion coefficient: It matches glass and ceramics and is suitable for sealing components.
Corrosion resistance: It is resistant to acid and alkali corrosion, but it is easily oxidized at high temperatures (inert gas protection is required).
Applications
1. Electronics industry:
Semiconductor devices (such as heat sinks, sputtering targets).
Vacuum electron tubes, X-ray tube anodes.
2. High temperature field:
High temperature furnace insulation screens, thermal field support parts.
Aerospace engine parts.
3. New energy/nuclear industry:
Nuclear reactor coating materials, solar cell electrodes.
4. Other uses:
Medical equipment (such as radiotherapy collimators), glass melting electrodes.
FAQ
1. What are the main characteristics of molybdenum foil?
High melting point (2620℃), suitable for extreme high temperature environments.
Excellent thermal/electrical conductivity, high temperature stability is better than copper.
Low thermal expansion coefficient, compatible with ceramics and glass.
Corrosion resistant (except high temperature oxidation), need to be used for a long time in an inert gas or vacuum environment.
2. What is the typical thickness and width range of molybdenum foil?
Thickness: 0.01mm (10μm) ~ 0.2mm (ultra-thin foil can reach 5μm).
Width: 1mm ~ 500mm (custom slitting is supported).
Common forms: roll or sheet, the surface can be polished or plated.
3. In which fields is molybdenum foil used most?
Electronics/semiconductors: sputtering targets, vacuum tube components, heat dissipation substrates.
High temperature industry: furnace insulation layer, single crystal silicon growth thermal field components.
Aerospace: rocket nozzle coating, high temperature sensor.
Nuclear energy: Reactor neutron reflector.
4. Why is molybdenum foil prone to brittle cracking? How to avoid it?
Reason: Molybdenum has poor ductility at room temperature and is prone to stress cracking during processing.
Solution:
Heating processing: Stamping or bending at above 200°C.
Slow cutting: Use laser or EDM to reduce mechanical stress.
Annealing: High temperature annealing after processing to eliminate internal stress.
5. Are you a factory or manufacturer?
Yes, we are a factory but generally, we use our trading company to handle the business abroad. It will be convenient to receive the remittance and arrange the shipment.
6. What is the delivery method?
A: Generally, we send cargo by UPS, DHL or FedEx. Also, we can send by sea to seaport or by air to the closest airport.
Why Is Your Product So Cost-Effective?
We cut out the middlemen in the end-to-end manufacturing process. Rather than obtaining semi-finished goods from other suppliers, we obtain our raw material of APT powder directly from its source.
7. Do You Do Spot Quality Checks Or Full Checks?
100% full inspection. Inspectors will check the finished product individually, to ensure they adhere to all parameters. All unqualified products are discarded.
8. How Do You Ensure Your Lead Time?
We have an efficient Order Management System, from material preparation to machining, and finally to a full inspection. Every stage of production is strictly monitored and controlled to give you an accurate delivery time.
9. What is the MOQ of molybdenum foil strip
A: Depends on quantity, generally, no MOQ limit.
10. How to pay for it?
A: A bank transfer (T/T) will be acceptable.
11. What is the delivery time?
A: around 7-20 days which depends on the quantity and production.
12. What is kind of the package?
A: Generally, we use a carton case or plywood case with protective material inside to ensure the save of cargo
13. What is the lead time?
A: from order placed to cargo receiving will take around 10-25 days.
