Tantalum Rods Tantalum Bars

Tantalum Rods Tantalum Bars – Reliable Solutions for Extreme Environments 

Material Overview

Tantalum, hailed as the “King of Corrosion Resistance,” is a strategic metal for advanced industries and high-tech applications, renowned for its unrivaled corrosion resistance, ultra-high melting point, exceptional biocompatibility, and unique electrical properties:

• Ultimate Corrosion Resistance: Nearly inert at ambient temperatures, resistant to concentrated hydrochloric acid (37%), sulfuric acid (98%), nitric acid, and other aggressive media. Outperforms titanium and platinum, making it the optimal choice for chemical and medical equipment.
• High-Temperature Performance: Melting point of 3017°C, retaining strength and oxidation resistance under extreme heat. Ideal for vacuum furnaces and aerospace engine components.
• Medical-Grade Safety: Compliant with ISO 10993 biocompatibility standards, non-toxic and hypoallergenic, widely used in orthopedic implants and minimally invasive surgical tools.
• Superior Electrical Properties: High dielectric constant and stability, critical for high-end capacitor manufacturing.

Advantages

✔ Unmatched Resistance to Extreme Environments

• Chemical Inertness: Stable in strong acids (HCl, H2SO4, HNO3), molten alkalis, and high-temperature chlorides, with zero risk of crevice corrosion.
• High-Temperature Resilience: Zero oxidation below 1200°C, long-term usability in 1600°C vacuum environments.

✔ Advanced Customization Capabilities

• Precision Dimensions: Diameter 5mm to 150mm, custom lengths (up to 6 meters), tolerances as tight as ±0.02mm.
• Versatile Processing: Forged rods (high density), rolled rods (smooth surface finish), and surface treatments (anodizing/polishing/coatings).
• Material Options: Pure tantalum rods (Ta1, Ta2), tantalum-tungsten alloys (Ta2.5W, Ta10W), tailored for varying strength and temperature requirements.

Key Applications

• Chemical & Energy: Liners for acid reactors, nuclear fuel cladding tubes, electrolysis anodes.
• Medical & Life Sciences: Cranial reconstruction plates, vascular stents, endoscope components.
• Electronics & Semiconductor: High-performance capacitor sputtering targets, semiconductor etching rings.
• Aerospace: Rocket nozzle components, satellite thermal protection substrates.
