Nb50Ti50
Nb50Ti is a superconducting alloy composed of two elements, niobium and titanium. The content of titanium is generally in the range of 46% to 50% (mass fraction). It is one of the most widely used superconducting materials. This alloy has a high superconducting transition temperature and excellent mechanical properties, and is widely used in various fields requiring superconducting properties.
Physical properties of Nb50Ti

The technology of using two pure metals, niobium and titanium, to form electrodes in appropriate forms, melting them in a vacuum environment and forming ingots. Both niobium and titanium are active, refractory rare metals, and they can form solid solution alloys with each other. The alloy belongs to the type II superconductor and has a high upper critical field (Hc2). When the niobium-titanium solid solution alloy is treated at low temperature, a pinning phase can be precipitated, giving it a high critical current density.
The molten-cast niobium-titanium alloy has uniform composition and low impurity content.
