Manufacturing & Process Flow

Shaanxi Chuanghui Daye ensures every tantalum alloy bar is produced with precision and reliability through a controlled, step-by-step manufacturing process:

Raw Material Selection: Certified high-purity tantalum ingots or alloys (Ta-2.5W, Ta-10W, Ta-Nb) sourced from trusted suppliers.
Melting & Refining: Electron Beam or Vacuum Arc Melting (EBM/VAM) to ensure microstructural uniformity and impurity removal.
Forging: Multi-step hot forging enhances density and grain refinement for mechanical strength.
Rolling or Swaging: Precision forming to achieve required diameters and roundness.
Annealing: High-temperature vacuum annealing to relieve stress and improve ductility.
Straightening & Cutting: Bars are straightened and cut to standard or custom lengths with minimal tolerance deviation.
Surface Finishing: Machining, polishing, or pickling for a smooth and clean surface finish.
Inspection & Packaging: Each batch undergoes comprehensive testing and export-standard packing.

Quality Control & Inspection

Quality is our core commitment. Shaanxi Chuanghui Daye operates under an ISO 9001:2015 certified quality management system, ensuring each tantalum alloy bar meets the highest global standards.

Inspection & Testing Procedures:

Chemical Composition Analysis: Verified by ICP-OES or XRF to ensure compliance with ASTM B365/B708.
Mechanical Property Testing: Tensile strength, yield strength, and elongation measured per ASTM standards.
Ultrasonic & Eddy Current Testing: Detects internal flaws and ensures structural integrity.
Dimensional Accuracy Check: Precision measurement with ±0.02 mm tolerance.
Surface Examination: Manual and optical inspection for uniform texture and defect-free surfaces.
Hardness & Microstructure Analysis: Verifies metallurgical consistency and phase purity.

Each shipment is accompanied by a Mill Test Certificate (EN 10204 3.1) and optional third-party inspection reports (SGS, BV, or TUV).
