H.C. Starck, Newton, Mass., introduces the Ultra 76 Plus tantalum alloy, which is designed to combat aggressive hazardous-chemical corrosion in hot concentrated acids. The alloy is based on the Ta2.5W alloy, which improves corrosion resistance by minimizing hydrogen embrittlement, extending equipment life, and reducing operation downtime.
Ultra 76 Plus was designed by H.C. Starck’s Fabricated Products Division. It enables increased concentrations and operating temperatures in HCI, H2SO4, and other acids. It can add value to a multitude of products, from heat exchangers, condensers, and coils, to thermocouple protection sheaths, pumps, distillation columns, boilers, and condensers.
H.C. Starck’s high-tech materials — molybdenum, tungsten, tantalum, niobium, and their alloys — are excellent choices for applications in high temperatures and severe environments. Tantalum, in particular, is widely used in electronics, chemical processes, and biomedical industries, where its alloys provide cost-effective, long service-life solutions for mission-critical components. In addition, it enables users to eliminate separate “Platinum Spot Welding” steps.
