ASTM B708 Tantalum Alloy Plate

Tantalum metal is stable in air at room temperature, when heated above 500 ° C, oxidation is accelerated to produce Ta205. Tantalum has a series of excellent properties such as high melting point, low steam pressure, good cold working performance, high chemical stability, strong resistance to liquid metal corrosion, and large dielectric constant of surface oxide film, and has important applications in high-tech fields such as electronics, metallurgy, steel, chemical industry, cemented carbide, atomic energy, superconducting technology, automotive electronics, aerospace, medical health and scientific research.

Application Advantages

ASTM B708 Tantalum Alloy Plate is a high-performance material engineered for extreme chemical and thermal environments. With its superior corrosion resistance, ductility, and high melting point (over 3000°C), tantalum plate is the preferred choice for critical applications in:

• Chemical Processing: Ideal for acid-resistant linings, reaction vessels, and heat exchangers exposed to hydrochloric, sulfuric, and nitric acids.
• Electronics & Semiconductor: Used in sputtering targets, capacitors, and vacuum system components due to excellent conductivity and purity.
• Medical Equipment: Suitable for surgical implants and instruments thanks to its outstanding biocompatibility.
• Aerospace & Defense: Employed in propulsion systems, high-temperature shields, and structural components.
• Energy & Environmental Engineering: Essential in nuclear energy systems and corrosion-resistant assemblies for clean energy technologies.

Key Advantages:

• Excellent corrosion resistance to most acids
• High melting point and thermal stability
• Superb workability and weldability
• Long service life and minimal maintenance
• Compliance with ASTM B708 standards for quality consistency

Manufacturing & Process Flow

Shaanxi Chuanghui Daye Metal Material Co., Ltd. manufactures tantalum alloy plates through a rigorous and standardized process, ensuring optimal performance and precision:

1. Raw Material Selection: High-purity tantalum and alloying elements (Ta-2.5W, Ta-10W, Ta-Nb) are selected according to ASTM B708.
2. Melting & Refining: Electron beam or vacuum arc melting (EBM/VAM) ensures purity and homogeneity.
3. Forging & Rolling: Hot and cold rolling refines the grain structure, improving mechanical strength and flatness.
4. Annealing: Vacuum annealing enhances ductility and stress relief.
5. Surface Finishing: Grinding, polishing, or chemical cleaning for smooth, contamination-free surfaces.
6. Dimensional Cutting: Precision cutting to specified sizes with strict tolerance control.
7. Inspection & Testing: Each plate undergoes mechanical, dimensional, and non-destructive testing.
8. Packaging: Vacuum sealing and export-grade packing for shipment.

Quality Control & Inspection​​​​​​​​​​​​​​

Quality is embedded into every step of production under our ISO 9001:2015 certified management system.

Our comprehensive inspection program includes:

• Chemical Composition Analysis: Verified by XRF, ICP, or spectrometer to ensure conformity with ASTM B708.
• Mechanical Property Testing: Tensile strength, elongation, and hardness testing to guarantee performance.
• Dimensional Tolerance Check: Accurate to ±0.02 mm, ensuring plate uniformity.
• Surface Quality Control: Visual inspection for flatness, uniform texture, and defect-free surfaces.
• Non-Destructive Testing (NDT): Ultrasonic and eddy current testing for internal flaw detection.
• Final Review: Documentation and quality certification before dispatch.

All tantalum alloy plates are supplied with Mill Test Certificates (EN 10204 3.1) and optional third-party inspection reports (SGS, BV, TUV).

R&D and Customization

Driven by 30+ years of technical experience, our R&D team continues to advance material science in refractory metals. We specialize in:

• Custom Alloy Design: Tailoring Ta-W, Ta-Nb, and Ta-Mo compositions for enhanced strength or corrosion resistance.
• Precision Fabrication: Tantalum plate machining, punching, and deep processing upon request.
• Surface Treatments: Polishing, passivation, or sandblasting to meet client-specific performance needs.
• Dimensional Customization: Thickness range from 0.5 mm to 40 mm, width up to 1200 mm, length up to 3000 mm.
• Joint Development: Collaborative R&D with universities and industrial research centers for cutting-edge applications.
