Core Advantages
High-Purity Tantalum Materials
We source only high-grade raw tantalum to ensure excellent purity, consistency, and performance across all product forms — from sheets and wires to custom machined parts.
Advanced Production Technology
Utilizing precision rolling, forging, and CNC machining techniques, we deliver tantalum products with tight tolerances, smooth surfaces, and stable mechanical properties.
Strict Quality Control System
Every batch undergoes rigorous inspections including chemical composition analysis, mechanical testing, and non-destructive evaluation to guarantee compliance with international standards.
Customization for Critical Applications
From medical-grade implants to aerospace-grade components, we support custom orders based on drawings or specifications, meeting exact application needs.
Tantalum Products production process
1. Raw Material Selection
We begin with high-purity tantalum ingots or powder, sourced from certified suppliers to ensure consistent quality and trace elements control.
2. Melting & Purification
Tantalum is melted in a vacuum or electron-beam furnace to remove impurities and achieve desired purity levels, often exceeding 99.95%.
3. Hot Forging & Rolling
The purified tantalum is hot forged and rolled into bars, sheets, or blanks under tightly controlled temperatures to refine grain structure and enhance mechanical properties.
4. Annealing
Material is heat-treated in a vacuum or inert atmosphere to relieve internal stress, improve ductility, and stabilize structure for further processing.
5. Precision Machining
Depending on the final product, tantalum is machined, drawn, or ground to achieve the exact size, shape, and surface finish — including wires, rods, tubes, and custom parts.
6. Final Inspection & Packaging
All finished products undergo dimensional checks, surface inspection, and chemical/physical testing before being safely packaged for export to global customers.
Tantalum Quality Testing
Chemical Composition Analysis (ICP/OES)
To ensure material purity, we use advanced spectrometry methods such as Inductively Coupled Plasma (ICP) or Optical Emission Spectroscopy (OES) to accurately detect and quantify elemental content — confirming compliance with ASTM or customer standards.
Mechanical Property Testing
Tensile strength, yield strength, elongation, and hardness are measured using standardized equipment to validate the mechanical performance of each batch, especially for structural or high-stress applications.
Ultrasonic & Surface Defect Inspection
We conduct ultrasonic testing (UT) and visual inspections to detect internal flaws or surface imperfections, ensuring the integrity of tantalum sheets, rods, and machined parts before final delivery.
Frequently Asked Questions
What are the main grades of tantalum you supply?
We primarily supply Ta1 and Ta2 grades (ASTM designations RO5200 and RO5400), which are widely used for high-purity, high-performance applications across electronics, chemical processing, and medical fields.
Is tantalum resistant to corrosion?
Yes, tantalum offers exceptional corrosion resistance, especially to strong acids such as hydrochloric, sulfuric, and nitric acid, making it ideal for chemical equipment and harsh environments.
Can you provide custom tantalum parts based on drawings?
Absolutely. We specialize in CNC-machined tantalum parts tailored to your specifications or technical drawings. Our team can support prototypes to full-scale production.
