Molybdenum Metal Bar

Introduction of molybdenum bar:

Our molybdenum flat bar is sintered with high-purity molybdenum powder (≥99.95%), with a high melting point (2620°C), excellent thermal conductivity and low thermal expansion, and is particularly suitable for high temperature, vacuum and corrosive environments. The shapes of our molybdenum bar include round and square; optional materials include pure molybdenum, TZM (titanium zirconium molybdenum alloy) and molybdenum lanthanum alloy, which meet the ASTM B387 standard. The size of molybdenum bar can be customized according to needs.

Advantages of molybdenum metal bar:

1. Our molybdenum metal bar's advanced vacuum sintering + forging process achieves uniform grains and high density, more stable thermal conductivity at high temperatures, and extended service life.

2. Our molybdenum metal bar undergoes cross-batch testing to stabilize the distribution of alloy elements and microstructure, reducing the risks of customers' subsequent processing or high-temperature applications.

3. Our molybdenum metal bar can recommend suitable alloy solutions based on the actual operating temperature, load conditions and corrosive environment of customers.

4. Each of our molybdenum metal bars undergoes ultrasonic flaw detection and full dimensional inspection before leaving the factory to prevent cracks and internal defects from flowing into the downstream.

5. Our molybdenum metal bar complies with EU RoHS and REACH requirements, and third-party test reports or material certificates (MTC) can be provided on demand.

Parameters of pure molybdenum bar:

Process of pure molybdenum bar:

1. Our pure molybdenum bar can provide a variety of process methods according to different customer needs: including sintering, forging, turning and centerless grinding, etc. The diameter range of pure molybdenum bar covers from about 3mm (0.125 inches) to 152mm (6.0 inches), and the length can reach up to 8 meters (26 feet).

2. The surface state of pure molybdenum bar can be selected as black skin (surface with oxide layer, for self-treatment before high temperature use), pickling (remove oxide layer, the surface is cleaner), or bright surface after centerless grinding (Ra≤0.8μm).

Dimensional accuracy of pure molybdenum bar:

1. The diameter tolerance of our molybdenum flat bar can reach ±0.01mm (customized according to needs). And the length and straightness of molybdenum flat bar meet international standards.

2. Our molybdenum flat bar has a dense and uniform organizational structure, ensuring stability at high temperatures and meeting downstream processing and direct assembly requirements.

Application of molybdenum flat bar:

Our molybdenum flat bar can be used in multiple fields, including but not limited to the following industries

1. Our molybdenum flat bar can be used as electric vacuum devices, high-temperature heating elements and supports for vacuum furnaces.

2. Our molybdenum metal rod can be used as fixtures, electrodes and structural parts in the semiconductor and optoelectronic industries.

3. Quartz glass and ceramic kiln electrodes can still conduct electricity stably at high temperatures of 1300°C.

4. Our molybdenum metal rod can be used as rare earth and special alloy industrial electrodes and structural parts.

5. Our molybdenum metal rod can be used as high-temperature resistant samples for experiments in scientific research institutes and universities.

FAQ of molybdenum metal rod:

Q1: What molybdenum alloys can your company provide?

We can supply molybdenum metal rod (Mo ≥99.95%), ferromolybdenum, molybdenum powder, etc., all in accordance with ASTM standards.

Q2: Can we customize molybdenum metal rod according to my drawings or non-standard requirements?

Yes, we have independent machining and sintering workshops to meet the size and processing requirements of special molybdenum metal rods.

Q3: How long is the delivery time of molybdenum metal rods?

The regular sizes of molybdenum bars are in stock; non-standard customization is usually completed and shipped in 2-4 weeks.

Q4: How to remove the black oxide layer on the surface of molybdenum bar?

Molybdenum bar can be treated with strong acid or physically polished, and Hongtuo can also provide grinding surface to reduce the customer's subsequent processing steps.

Q5: Is international transportation safe?

All pure molybdenum bar/bars are fixed with customized wooden boxes + soft packaging to prevent impact and displacement during transportation.
