Product Overview
Low-oxygen medical grade Nitinol powder 15-53 microns is a highly spherical, gas-atomized nickel-titanium alloy powder engineered specifically for powder-bed fusion additive manufacturing of medical devices. With a precisely controlled particle size distribution (D10: 15 μm, D50: ~30 μm, D90: 53 μm) and oxygen content below 500 ppm, this powder delivers excellent flowability (Hall flow < 25 s/50g), high apparent density (> 4.0 g/cm³), and consistent layer spreading — critical parameters for producing dense, defect-free SLM-printed Nitinol components with reliable superelastic and shape memory properties.
Princeton Nitinol is a leading Nitinol powder supplier for medical device additive manufacturing in the United States. Our VIM+EIGA production route ensures batch-to-batch consistency in chemical composition, transformation temperatures, and particle morphology. Every powder lot is fully characterized with: chemical analysis (Ni, Ti, O, C, N, H, Fe), DSC transformation temperature report (Af, As, Ms, Mf) per ASTM F2004, laser diffraction particle size distribution (D10, D50, D90), SEM morphology imaging, Hall flow rate, apparent density, and tap density. Custom particle size cuts and non-standard Af temperatures available on request.

Frequently Asked Questions
Low-oxygen medical grade Nitinol powder 15-53 microns (D10-D90) is optimized for selective laser melting (SLM), direct metal laser sintering (DMLS), and metal injection molding (MIM) of medical devices. The fine, highly spherical particle distribution ensures excellent powder flowability, high packing density, and uniform melting — critical for producing dense, defect-free Nitinol implants with consistent superelastic and shape memory properties. Princeton Nitinol powder is ASTM F2063 and ISO 5832-11 compliant.
Oxygen content directly impacts Nitinol transformation temperatures (Af). Even small increases in oxygen shift Af temperatures, reduce ductility, and degrade superelastic plateau stress. Princeton Nitinol low-oxygen powder (< 500 ppm O) ensures stable, predictable Af temperatures, consistent mechanical properties, and full ASTM F2063 compliance — essential for FDA-regulated medical device manufacturing.
15-53 micron Nitinol powder is the finer grade, optimized for high-resolution SLM/DMLS printing of small, intricate medical devices (stents, heart valve frames, endoscopic components) requiring thin walls and fine surface finish. 45-106 micron powder is the coarser grade, better suited for EBM (electron beam melting), larger MIM components, and applications prioritizing build rate over surface resolution. Princeton Nitinol supplies both grades with consistent particle size distribution.
Princeton Nitinol powder is produced via vacuum induction melting (VIM) followed by electrode induction gas atomization (EIGA) under inert argon atmosphere — a crucible-free process that minimizes oxygen pickup and ensures exceptional chemical homogeneity. The powder is then sieved to precise particle size distributions (15-53 μm or 45-106 μm), with every lot tested for chemical composition, particle size distribution, flow rate, apparent density, and tap density.
