H.C. Starck NRC® 4N5 (UNS R05200) Electron Beam Melted Tantalum
Categories: Metal; Nonferrous Metal; Refractory Metal; Pure Element

Material Notes: Applications: NRC® ETA Tantalum metal products are used where purity and or ductility of the tantalum metal is more important than strength or grain size. Consequently, their primary applications are in sputtering, nickel based superalloys, explosion bonding of liners for corrosion resistance, medical, and ordnance applications All grades meet ASTM requirements.

Forms Available: Sheet, Plate, Tube, Rod, Wire and Bar.

Typical Purity: Purity refers to 100% minus total metallic content only, gases are omitted from the calculation. Metallic impurities are measured by GDMS, gases by Leco.

Metallurgical Characteristics: Material is single-phase tantalum. Stress relieve at 1500°F, re-crystallize at 1900°F - 2100°F.

Information provided by H.C. Starck.
