H.C. Starck Ultra 76 Alloy (Ta 2.5%W)
Categories:	Metal; Nonferrous Metal; Refractory Metal
Material Notes:	Benefits: Significantly improved corrosion resistance in HCl and H₂SO₄ acids. Minimized hydrogen embrittlement rates compared to standard NRC®76 Up to 100 times lower in HCl acid Up to 10 times lower in H₂SO₄ acid Eliminates the need for a separate Pt application step to protect against H embrittlement. Maintains all the excellent mechanical properties of NRC®76. Potential for increased operating temperatures in both HCl and H₂SO₄. Applications: High strength alloy for corrosion applications in heat transfer equipment, vessels, piping, etc., and all applications where tantalum's physical properties are desired at a higher strength level than pure tantalum, and better corrosion resistance in HCl and H₂SO₄ acids. Forms Available: Foil, Sheet, Welded Tubing, Rod, Plate, Wire and Bar. Metallurgical Characteristics: Material is single-phase tantalum with tungsten and platinum group metals in solid solution, stress relieved material at 2000°F, re-crystallized material at 2400°F. Information provided by H.C. Starck.
