Sintavia, LLC, Hollywood, Florida, USA, has developed proprietary material parameters for alloy C103, a high-performance niobium alloy suited for rocket, jet and satellite propulsion applications. The refractory metal, which can be difficult to additively manufacture, was developed on an M290 AM machine from EOS, and marks the twenty-ninth proprietary material developed by Sintavia for use by its aerospace, defence and space OEM customers.
“Due to its extremely high melting point, niobium is widely recognised as an excellent material for space propulsion applications, specifically reaction control thrusters and attitude control thrusters,” stated Pavlo Earle, Sintavia’s VP of Technology Engineering. “With this development, Sintavia is able to offer its space customers components that embody industry-leading mechanical properties. When combined with Sintavia’s equally best-in-class design and additive production capability, our C103 parameters offer our customers a high-quality and reliable industrial solution for extreme temperature applications.”
The mechanical properties of Sintavia’s C103 include an as-built density of 99.94% and a Z-direction elongation of 32% after a standard stress relief cycle. Full performance data for Sintavia’s C103 parameter set can be found on the company’s website.
