Abstract
Nb--Sn precursor articles are described that include a Nb alloy article that is at least partially coated with a layer of a Sn alloy, such as a Sn--Cu alloy. The precursor articles described herein have a controlled concentration of the impurity elements As and S in the Sn alloy layer. The concentration of these elements in the Sn alloy layer is less than or equal to 50 ppm by weight. This invention also describes a method for making Nb--Sn precursor articles having a controlled concentration of As and S impurities.
