Products Description
Molybdenum (Mo) is an ideal heating element material for vacuum furnaces, high-temperature sintering furnaces, single crystal growth furnaces and other equipment due to its high melting point (2623°C), low vapor pressure, good high-temperature strength and corrosion resistance.
Molybdenum heating elements for vacuum furnaces are commonly used in high temperature furnaces. Molybdenum can be used in high temperature vacuum furnaces due to its high melting point and high strength at high temperatures.
Molybdenum heating elements can be expected to maintain temperatures up to about 1900°C under appropriate conditions. They are widely used in high temperature resistance furnaces, sapphire growth furnaces, etc. Molybdenum heating elements are used in vacuum furnaces for high temperature treatment, sintering and other material preparation processes.
Due to the high melting point and high temperature resistance of molybdenum, these heating elements are able to continuously provide the required high temperature in a vacuum environment.
Type and Size
Molybdenum heating elements can be welded and sliced. Molybdenum heating elements should be made of one continuous piece of wire, rod, or ribbon. Standard availability is described below. Other sizes and tolerances are available.

Applications and common Types of Molybdenum Heating Elements
(1) Wire heating element
Application: small vacuum furnace, tubular furnace
Specification: diameter 0.5~5mm, spiral or wavy winding
Features: fast heating, but easy to deform at high temperature (support structure required)
(2) Rod/plate heating element
Application: large high-temperature furnace (such as sintering furnace, CVD furnace)
Specification:
Rod: diameter 5~50mm, length up to 2m
Plate: thickness 1~10mm, customized shape (such as U-shaped, W-shaped)
Features: large current carrying capacity, long life, but high cost
(3) Mesh heating element
Application: uniform heating scene (such as photovoltaic single crystal furnace)
Features: uniform heat radiation, but low mechanical strength
FAQ of Molybdenum Heating Elements
Are you a factory or manufacturer?
A: 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.
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?
A: 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.
Do you do spot quality inspection or full inspection?
A: 100% full inspection. Inspectors will check the finished product individually, to ensure they adhere to all parameters. All unqualified products are discarded.
How do you ensure your lead time?
A: 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.
What is the MOQ ?
A: Depends on quantity, generally, no MOQ limit.
How to pay for it?
A: A bank transfer (T/T) will be acceptable.
What is the delivery time?
A: around 7-20 days which depends on the quantity and production.
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
What is the lead time?
A: from order placed to cargo receiving will take around 10-25 days.
