Abstract: 
The brittle intermetallic compound Nb3Sn can be produced in multifilamentary form by using ductile precursor materials and a final diffusion heat treatment. The widely used bronze route processed conductors can not explore completely the critical current capabilities of Nb3Sn because of the high amount of CuSn in the conductor cross section. Other processes can achieve higher overall critical current densities like internak Sn routes or Nb tube methods. Despite this fact, bronze route conductors are better suited for most applications. For NMR spectroscopy homogeneous defect free conductors with high "n" values are needed as achievable easily with the hard bronze matrix, whereas the homogeneity of wires produced by other processes tends to deteriorate due to the complex deformation characteristics. For accelerator and fusion applications wires with low magnetization and AC losses can be produced by an appropriate redistribution of the bronze without reducing overall critical current density.
