Engineers are looking for higher quality metal alloys to solve design problems. Two examples of current substitution trends: Titanium is replacing copper-nickel alloys in large desalinization plants. In a separate development, metallurgical-bonded, nickel-based alloy clad pipe is replacing conventional corrosion-resistant alloy pipe in sour gas applications. The trends were reported by L. Patrick Hassey, CEO of Allegheny Technologies, in a recent conference call with analysts. Hassey retired on May 1.
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
