3rd-Party Material Testing of Tantalum
X-medics uses independent ISO 17025 accredited laboratories for material testing of tantalum wire as well as all material used in fabrication tantalum beads / balls / spheres. The independent material testing report is enclosed together with the certificate package supplied by x-medics.
The chemical analysis is performed to ensure that the tantalum materials fulfills the requirements in ASTM F560 / ISO 13782:
Element | R05200 * max % (m/m) |
R05400 ** max % (m/m) |
---|---|---|
Carbon | 0.010 | 0.010 |
Oxygen | 0.015 | 0.03 |
Nitrogen | 0.010 | 0.010 |
Hydrogen | 0.0015 | 0.0015 |
Niobium | 0.10 | 0.10 |
Iron | 0.010 | 0.010 |
Titanium | 0.010 | 0.010 |
Tungsten | 0.050 | 0.050 |
Molybdenum | 0.020 | 0.020 |
Silicon | 0.005 | 0.005 |
Nickel | 0.010 | 0.010 |

*) Electron-beam or vacuum-arc cast tantalum.
**) Sintered tantalum.
***) The percentage of tantalum is determined by difference and need not be determined or certified.
Carbon
Carbon is typically analysed using the Combustion Infrared Detection Method according to ASTM E1019. In this way, carbon presence from trace amounts less than 5 ppm can be detected.
Oxygen and nitrogen
Oxygen and nitrogen contents are typically determined by the Inert Gas Fusion Method according to ASTM E1019. This method shows trace amounts less than 5ppm.
Hydrogen
Hydrogen is typically determined by the Vacuum Hot Extraction method according to ASTM E146.
Iron
Iron is typically analysed by Atomic Absorption (AA) Spectroscopy as described in ASTM E699. Atomic Absorption provides accurate detection of trace metals.
Niobium, Titanium, Tungsten, Molybdenum, Silicon and Nickel
These trace metals are typically determined by Direct Current Plasma Emission Spectroscopy (DCPES) according to ASTM E1097. DCPES is a versatile and efficient method for general testing of metallic content.
