Manufacturing Process – Electron Beam Vacuum Melting
We adopt Electron Beam Vacuum Melting (EB) as the core melting process for tantalum ingots.
Process Advantages:
● Ultra-high vacuum environment minimizes gas contamination
● Superior removal of oxygen, nitrogen, hydrogen, and metallic impurities
● Highly uniform microstructure and chemical composition
● Enhanced corrosion resistance and service life
● Excellent consistency between batches
This process is particularly critical for applications requiring high purity, long-term stability, and extreme corrosion resistance.
Quality Control
Mill Test Certificates (MTC) are provided for each shipment upon request.
- Chemical composition analysis
- Dimensional and surface inspection
- Mechanical property testing
- Batch traceability and documentation
