Rhodium, the rarest occurring metal.

Renishaw PLC, Gloucestershire, UK, has delivered a crucial saving for a metal additive manufacturing (AM) process that involves rhodium and platinum, two metals that are generally too expensive to use in industrial applications. However, when alloyed, weight loss at high temperatures occurs slower than pure platinum, providing industrial value.

The Curtiss-Wright Engineered Pump Division, Bethlehem, Pennsylvania, Bechtel Plant Machinery, Inc., Monroeville, Pennsylvania, and Sintavia LLC, Fort Lauderdale, Florida, have collaborated to produce the first submarine component using qualified metal additive manufacturing (AM). Sintavia, a manufacturer of critical defense components, supplied an AM impeller that underwent rigorous qualification and testing at Curtiss-Wright’s facility. This partnership aims to expand the use of AM parts in naval defense applications.

Neodymium praseodymium oxide powder produced by MP Materials.

Oak Ridge National Laboratory (ORNL) has played a significant role in advancing the extraction of rare earths in the U.S. Rare earths, especially neodymium and praseodymium, are essential for powerful permanent magnets used in a wide array of industries. The U.S. and allied nations are increasingly concerned about China's dominance in the rare earth market, which produces about 90% of processed rare earths. In response, the U.S., Australia, and Canada are investing heavily in their own production capabilities to secure a stable supply chain.
