Excellent mechanical and electrical properties make Niobium-Titanium (NbTi) the preferred conductor for accelerator magnets with operating fields up to 8 T. In order to surpass this threshold, materials with higher critical field are required. Among these, Niobium-Tin (Nb3Sn) is in the most advanced state of development. Nb3Sn wires carry sufficient current densities to sustain coil windings operating in the 15 T range, and can be produced in multi-km lengths with uniform properties. Following extensive R&D programs, Nb3Sn technology is enabling a 10-fold increase of the LHC luminosity, opening the way to its application in future higher energy colliders. The use of High Temperature Superconductors such as YBCO and Bi-2212 is also being actively explored to surpass the intrinsic limits of Nb3Sn. While these materials can in principle support operating fields well above 20 T, many technological challenges need to be addressed to exploit their fundamental properties in practical magnet designs. The most significant achievements to date, remaining issues and future directions are discussed.
