Sintavia’s alloy C103 material parameters enable space components with properties that withstand extreme temperatures
November 30, 2022
HOLLYWOOD, Fla.—Sintavia, LLC, has developed proprietary material parameters for alloy C103, a high-performance niobium alloy that is well suited for rocket, jet, and satellite propulsion applications, the company said in a release.
Sintavia is a designer and additive manufacturer of complex mechanical systems for the aerospace and defense industry. Its alloy C103 is reported to offer mechanical properties that include an as-printed density of 99.94 percent and a Z-direction elongation of 32 percent after a standard stress relief cycle.
“Due to its extremely high melting point, niobium is widely recognized as an excellent material for space propulsion applications, specifically reaction control thrusters and attitude control thrusters,” said Sintavia Vice President of Technology Engineering Pavlo Earle, in the release. “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 refractory metal, difficult to print without extensive parameter development, was developed on an EOS GmbH M290 printer. It represents the 29th proprietary material parameter developed by Sintavia for use by its OEM customers in the aviation/aircraft, defense, and space markets, according to the release.
Earle added that Sintavia is currently developing proprietary standards for other refractory materials for use across the aerospace and defense industry. Full performance data for Sintavia’s C103 parameter set can be found on the company’s website: www.sintavia.com/materials-guide/.
