Manufacturing & Process Flow

Shaanxi Chuanghui Daye Metal Material Co., Ltd. follows a precision-controlled production process to ensure each ASTM B365 Tantalum Alloy Wire meets international standards.
Production steps:

1. Raw Material Selection: Certified tantalum ingots and alloys.
2. Melting: Electron beam or vacuum arc melting to ensure purity and homogeneity.
3. Forging & Rolling: Hot and cold working to achieve the required wire diameter and density.
4. Drawing Process: Multi-stage drawing with annealing for uniform grain structure.
5. Surface Treatment: Polishing and cleaning to remove oxides and impurities.
6. Final Inspection: Dimensional, chemical, and mechanical tests before delivery.

Each stage is monitored under ISO 9001:2015 quality control, ensuring stable performance and dimensional accuracy.
