Access a comprehensive, professionally formatted Material Test Certificate according to EN 10204-2004: 3.1 for Tantalum Ta-10W (ASTM B365 UNS R05255). Inspect the exact documentation your QA and engineering teams will receive with every maximum-strength, extreme corrosion-resistant fastener order from Ananka Fasteners.
What's Inside This Tantalum Ta-10W MTC Certificate
This sample mill test certificate mirrors the rigorous QA documentation package standard for our highest-strength Tantalum-Tungsten alloy fasteners, utilized where unparalleled acid resistance must be paired with extreme mechanical stiffness and high-temperature stability.
- Full Traceability: Certified with TC No.: S74/26-XX and corresponding ASTM B365 specifications for tantalum alloy rod and wire.
- Maximum Tungsten Alloying: Detailed breakdowns verifying the heavy 10% nominal Tungsten (W) addition (9.0% - 11.0%). This specific metallurgy creates the strongest commercially available Tantalum alloy.
- Trace Gas Controls: Explicit verification of tightly controlled interstitial elements like Oxygen (O), Nitrogen (N), and Hydrogen (H) to prevent high-temperature embrittlement during processing.
- Mechanical Properties (Annealed): Comprehensive reporting of Tensile Strength (515.50 MPa), Yield Strength (385.20 MPa), Elongation (18.50%), and Hardness (95 HRB). Yield strength is nearly double that of pure Tantalum.
- Quality Compliance: 100% visual inspection carried out and verified free from defects and radioactive contamination.

Technical FAQs — Tantalum Ta-10W MTC Certificate
Why specify Ta-10W over pure Tantalum (R05200)?
Ta-10W (UNS R05255) includes a 10% Tungsten addition, which nearly doubles the yield strength and significantly increases the tensile strength compared to pure unalloyed Tantalum. It is specified when components must operate in extremely corrosive environments but are also subjected to high mechanical stress, pressure, or elevated temperatures that pure Tantalum cannot withstand structurally.
Does the 10% Tungsten addition affect corrosion resistance?
Virtually not at all. Ta-10W retains the identical "glass-like" corrosion resistance to hot, concentrated acids (like hydrochloric, nitric, and sulfuric) as pure Tantalum, while offering vastly superior mechanical properties.
Are the materials free from radioactive contamination?
Yes, the document strictly states that the material is free from radioactive contamination and undergoes a 100% visual inspection to ensure it is free from defects.
