Series: ASM Handbook
Volume: 2
Publisher: ASM International
Published: 01 January 1990

EISBN: 978-1-62708-162-7
... Abstract Niobium-titanium alloys (NbTi) became the superconductors of choice in the early 1960s, providing a viable alternative to the A-15 compounds and less ductile alloys of niobium-zirconium. This can be attributed to the relative ease of fabrication, better electrical properties...
